Continence following radical retropubic prostatectomy using self-reporting instruments.
PURPOSE: We performed a global self-assessment of continence following radical retropubic prostatectomy (RRP) and determined how this global self-assessment of continence correlates with commonly used definitions of continence. MATERIALS AND METHODS: Between October 2000 and February 2002 all men who underwent RRP were encouraged to complete the University of California-Los Angeles Prostate Cancer Index 3, 6, 12 and 24 months postoperatively. Beginning October 2002 a single question capturing the patient global self-assessment of continence status was added to the postoperative continence assessment. The study design was cross-sectional since only continence surveys submitted between October 2002 through February 2003 were evaluated. Sensitivity, specificity and kappa coefficient was determined for the relationship between the patient global assessment of continence vs the definition of continence based on pad requirement, problem due to incontinence and frequency of incontinence. RESULTS: Continence progressively improved 3 to 24 months following RRP for all continence outcomes. At 24 months following RRP 97.1% of men considered themselves continent, while 97.1%, 94.1% and 97.1% were considered continent using continence definitions, including the requirement of no or 1 pad in a 24-hour interval, no or slight bother due to incontinence and total control or occasional dribbling, respectively. Our 3 definitions of continence derived from responses to the University of California-Los Angeles Prostate Cancer Index had excellent agreement with patient global self-assessment of continence (kappa coefficients between 0.76 and 0.83). CONCLUSIONS: The majority of men achieve continence without invasive intervention following RRP. Final continence status should be ascertained at 24 months. The patient global assessment of continence provides face validity for other definitions of continence based on responses to validated self-administered questionnaires.

Continent urinary diversion and the exstrophy-epispadias complex.
PURPOSE: The use of continent urinary reservoirs has gained wide acceptance, particularly in urinary reconstruction in children with a small capacity or neuropathic bladder. When augmentation cystoplasty is combined with clean intermittent catheterization, patients are often able to achieve continence with low intravesical filling pressures and renal preservation. Often this approach requires fashioning a continent cutaneous stoma, which remains the most challenging aspect of continent urinary reservoirs. We analyzed our experience with continent diversion in patients with exstrophy-epispadias to determine complications and long-term results. MATERIALS AND METHODS: We performed a retrospective database review of 704 cases of exstrophy-epispadias. Medical records were then used to identify those patients who had undergone creation of a continent urinary reservoir. Charts were reviewed to determine initial diagnosis, augmentation technique, continence mechanism, age, preoperative and postoperative bladder capacity, continence status and complications. RESULTS: Of the 91 patients identified (68 male, 23 female) who had undergone continent urinary diversion classic bladder exstrophy was present in 80, cloacal exstrophy in 8, complete male epispadias in 2 and female epispadias in 1. The most common techniques for augmentation and continent diversion were ileocystoplasty (41 patients [45%]) and sigmoid cystoplasty (30 [33%]), respectively. Appendix was used in 67 patients (74%) and variants of the Mitrofanoff procedure using segments of tapered ileum or ureter were used to create a continent stoma in 10 (11%). Bladder neck transection was performed in 59 patients (65%). Mean age at augmentation and continent diversion was 8 years (range 2 to 25), with a mean preoperative bladder capacity of 77 cc (15 to 220). Mean followup was 6 years (range 6 months to 12 years). Of the 91 patients 85 (93%) were continent with clean intermittent catheterization per stoma. Of these 85 patients 13 required anticholinergics and alpha-agonists to achieve continence. Six patients (7%) were incontinent after the procedure. Analysis of bladder capacity measurements after augmentation and continent diversion revealed that mean postoperative volume and mean volume increase were 404 cc (range 250 to 640) and 524%, respectively. The most common complications were bladder stone formation (24 patients [26%]) and stomal stenosis (21 [23%]). Bladder stones recurred in 9 patients and stomal stenosis in 3. Other less common complications were vesicourethral fistula (3 patients) and a small bladder perforation (2). CONCLUSION: Augmentation and continent diversion procedures can increase the functional capacity of the small contracted noncompliant exstrophic bladder, and allow the vast majority of patients to achieve continence and preserve renal function. Bladder calculi and stomal stenosis pose the most significant long-term complications in these patients.

Continent catheterizable channels and the timing of their complications.
PURPOSE: We reviewed our experience with continent catheterizable channels with interest in the timing of conduit related complications. MATERIALS AND METHODS: A retrospective review was performed of the outcome of continent catheterizable channels in all patients between 1998 and 2003 who had undergone construction of an antegrade continence enema and/or a Mitrofanoff procedure using appendix, small bowel or continent cutaneous vesicostomy. We performed a total of 117 such stomas in 37 male and 41 female patients 2.5 to 20 years old (mean age 8.9). For the antegrade continence enema we used appendix in 92% of cases, an ileal Yang-Monti tube in 6% and a cecal tube in 2%. For the continent catheterizable channel we used appendix in 43% of cases, a Yang-Monti tube in 38% and continent cutaneous vesicostomy in 19%. RESULTS: Continence was achieved in 98% of patients. Followup was 6 to 71 months (mean 28.4). There were 27 channel related complications (23%). Stomal stenosis occurred in 7 antegrade continence enema procedures (14%) within 1 to 10 months (mean 6.2) and in 9 continent bladder channels (13%), including 5 continent cutaneous vesicostomies, within 1 to 24 months (mean 9.4) after surgery. False passages occurred in 5 antegrade continence enema procedures (10%) within 1 to 13 months (mean 3.6) and in 4 continent catheterizable channels (6%) within 1 to 13 months (mean 6.5) after surgery. Of patients with stomal stenosis 50% were treated with surgical revision, while the remainder was successfully treated with dilation. Most false passages were managed by catheter drainage alone. Reasons for revision were contained perforation, colovesical fistula and inability to catheterize. Patient noncompliance appeared to have a role in stomal stenosis. CONCLUSIONS: Continent catheterizable stomas help patients achieve bowel and bladder continence. Stomal incontinence after reconstruction is rare. In our experience most stoma related complications occurred in the first year after reconstruction. Experience with more patients and longer followup will help determine whether such problems continue to accumulate with time or whether continent stomas function well with time, particularly after the initial period of healing.

Factors that influence outcomes of the Mitrofanoff and Malone antegrade continence enema reconstructive procedures in children.
PURPOSE: Surgical techniques that provide adequate urinary and fecal continence in children with neurogenic bladder and bowel dysfunction are becoming increasingly used. We reviewed our experience and discuss factors that influence outcome. MATERIALS AND METHODS: Between 1994 and 2000, 65 stomal procedures were performed in 47 patients. For the urinary continent catheterizable channel we used appendix in 60% of cases, a continent bladder tube in 20%, a Yang-Monti tube in 16% and ureter in 4%. For the antegrade continence enema continent catheterizable channel we used appendix in 85% of cases, a Yang-Monti tube in 5% and a cecal tube in 10%. In the 19 patients who underwent simultaneous Mitrofanoff and antegrade continence enema procedures the urinary continent catheterizable channel was appendix in 21%, a Yang-Monti tube in 32% and continent vesicostomy in 47%. Patients were divided into 2 groups based on compliance status. In addition, percentile body weight for age was evaluated. RESULTS: Stomal continence was achieved in 63 of the 65 cases (97%). Of the patients who underwent the antegrade continence enema procedure 95% achieved continence via the rectum. Except for ureter stenosis rates according to continent catheterizable channel type did not differ greatly, namely 19% for appendix, 11% for the Yang-Monti tube, 22% for the bladder tube, 50% for ureter and 0% for the cecal tube. Infectious complications developed in 16 patients and 4 had stones. The rates of infection (p = 0.004), stomal stenosis (p = 0.001) and revision (p = 0.004) were statistically lower in the compliant group and the stone formation rate showed a trend favoring the compliant group (p = 0.11). No significant difference was noted for incontinence. Percentile weight predicted a higher rate of stomal stenosis with the highest rate of stomal stenosis overall in the greater than 100th percentile group. CONCLUSIONS: The Mitrofanoff and antegrade continence enema procedures are reliable and effective. Proper patient selection and surgical technique with a tension-free anastomosis are essential. The choice of tissue for constructing the continent catheterizable channel is not as important as patient compliance, age and possibly body habitus. This report reinforces the importance of careful screening, and rigorous preoperative and postoperative teaching to achieve overall patient success.

A population based analysis of continence outcomes and bladder exstrophy.
PURPOSE: Whereas the literature on bladder exstrophy is replete with outcomes of specific continence surgical procedures in highly select patients, there are no data on the outcomes related to continence for a complete exstrophy population, which is more comprehensive with respect to a variety of surgical procedures performed to achieve continence. To provide urologists and patients with an overview of potential continence outcomes devoid of any selection bias, we report on a comprehensive exstrophy population, focusing on the various procedures required for urinary continence. MATERIALS AND METHODS: We reviewed the charts of all patients with bladder and cloacal exstrophy who underwent a staged repair to achieve urinary continence at a single institution between 1988 and 1998. Urinary continence was then correlated to the types of surgical procedures, and subgroup analysis for predictors of urinary continence was performed. The type of bladder neck reconstruction allowed subgrouping cases into group 1-bladder neck reconstruction only, group 2-bladder neck reconstruction with augmentation and/or appendicovesicostomy and group 3-bladder neck closure. RESULTS: Of the 43 patients identified 26 were male, 4 had cloacal exstrophy and 3 had complex exstrophy variants with ectopic hindgut and spina bifida. Groups 1 to 3 comprised 9, 15 and 19 patients with urinary continence rates of 56%, 67% and 100%, respectively. The age at which patients became continent was delayed in groups 2 and 3 (8.2 and 8.7 years, respectively) compared to group 1 (4.8). Of all the potential variants measured gender was the strongest predictor of continence with 94% of females versus 69% of males achieving it. Of the males those with (57%) compared to those without (83%) a history of bladder neck stenosis or paraexstrophy flaps had worse continence. Repeat bladder neck reconstruction was only successful in 23% of patients. CONCLUSIONS: All patients can be rendered continent but many may achieve this successful outcome by other procedures following initial bladder neck reconstruction. When managing failed bladder neck reconstruction, the type of surgical repair chosen may need to address the need for enhanced bladder storage and the issue of potential bladder augmentation. The advances made in the treatment of the epispadiac urethra may now facilitate clean intermittent catheterization. Earlier recognition of the need for adjunctive storage procedures in addition to bladder neck reconstruction may facilitate the timing of providing enhanced continence, independence and self-esteem, and do so with fewer operative procedures. We speculate that the current complete urethral and bladder repair in newborns will add further to the storage functions of the native bladder tissues and improve the potential of achieving more effective bladder outlet control.

Prospective assessment of patient reported urinary continence after radical prostatectomy.
PURPOSE: Reported urinary continence rates after radical prostatectomy vary. Although modifications of radical prostatectomy meant to improve outcome, such as nerve sparing or bladder neck preservation, are in widespread use, to our knowledge evidence to support these practices based on patient report is scant. We evaluated the potential effects of nerve sparing and bladder neck preservation on urinary continence after radical prostatectomy, and assessed the impact of various urinary continence definitions on the observed outcome. MATERIALS AND METHODS: We prospectively evaluated a cohort of men with prostate cancer who elected surgery with and without nerve sparing, and bladder neck preservation as primary therapy. A total of 482 men completed a brief urinary continence questionnaire preoperatively and postoperatively at a median followup of 18 months. Urinary continence was followed prospectively using the questionnaire and patient reported urinary continence recovery was based on 3 definitions of continence. RESULTS: Median time to continence recovery based on patient reporting was significantly shorter in the nerve sparing than in the nonnerve sparing group when continence was defined as no urinary leakage (5.3 versus 10.9 months, p <0.01). A multivariate model controlling for baseline factors revealed that significant predictors of continence outcome were preoperative continence, patient age, nerve sparing and the interaction of nerve sparing with age (p <0.05). The definition of urinary continence also affected outcome. CONCLUSIONS: The nerve sparing technique of radical prostatectomy was associated with improved recovery of urinary continence in an age dependent manner, whereas bladder neck preservation was not beneficial. Patient age and the sensitivity of the incontinence definitions, as reflected by the associated variable rates of preoperative baseline incontinence, are significant contexts for interpreting urinary function data after radical prostatectomy. These factors may partially explain the variation in continence rates in the literature.

Appendiceal versus ileal segment for antegrade continence enema.
PURPOSE: To assess outcomes after the antegrade continence enema procedure, we present our results with an ileal segment or the appendix in children with severe bowel dysfunction. MATERIALS AND METHODS: A retrospective review of 45 children who had undergone the creation of a continent cecostomy for severe chronic constipation and fecal incontinence was performed. RESULTS: The appendix was used to create the continent cecostomy in 28 patients (group 1) and ileum 17 (group 2). Of 16 patients who underwent simultaneous construction of appendiceal Mitrofanoff neourethra, including continent catheterizable stoma, the appendix was split and used for the cecostomy and neourethra in 11. Overall, acceptable continence was achieved in 39 (87%) patients and total continence 31 (69%). No significant difference was noted in the rate of continence between groups 1 and 2. Nonstomal postoperative complications occurred in 5 patients in group 1 and 3 group 2. Complications that required reoperation related to the continent cecostomy occurred in 10 patients, including stomal stenosis in 8, with 6 group 1 and 2 group 2 (p >0.05), and stricture in 2, with 1 group 1 and 1 group 2. There were 2 patients who had previously undergone colostomy for intractable constipation who were undiverted at the time of the creation of continent cecostomy. Both were continent postoperatively. There were 3 patients, including those 2 who presented with chronic severe constipation of unclear etiology, who underwent colostomy for unrecoverable colonic dys-motility, of whom 1 subsequently required total colectomy. CONCLUSIONS: The creation of a continent cecostomy for antegrade continence enema is a successful management option in children with debilitating fecal incontinence, and may enable undiversion of an existing colostomy. The appendix and ileal segment are viable options for the procedure, with no significant difference noted in continence or complication rates.

Continence and classic bladder exstrophy treated with staged repair.
PURPOSE: Urinary continence rates after reconstruction of the urinary tract for classic bladder exstrophy are variable. We review our experience with procedures required to optimize continence. MATERIALS AND METHODS: We retrospectively reviewed the charts of patients with classic bladder exstrophy undergoing staged reconstruction between 1976 and 2001. Continence was reviewed and associated with the procedures performed. Patients were considered continent if dry for greater than 3 hours with no stress incontinence and dry at night. Partial continence required dryness for 1 to 3 hours, minor stress incontinence and occasional nighttime leakage. Incontinent patients were dry for less than 1 hour, had significant stress incontinence or were wet at night. Patients were followed for a median of 12.5 years. RESULTS: Continence was achieved in 43 of 48 patients (90%), partial continence in 4 (8%) and 1 (2%) remains incontinent. Continence occurred before bladder neck repair in 4 patients. Bladder neck repair alone (without augmentation) was performed in 38 patients at a median of 4.25 years, resulting in continence in 13 patients (34%). However, 6 of these 13 patients later required augmentation. Augmentation was performed in 33 patients, with 30 (91%) attaining continence after this procedure. Of those continent patients 10 void per urethra, and 8 void and use clean intermittent catheterization. Of the patients treated with bladder augmentation 93% required clean intermittent catheterization. CONCLUSIONS: Continence can be achieved in most patients with classic bladder exstrophy. However, augmentation was required in 30 of 43 patients (70%). Bladder neck reconstruction alone resulted in continence in only a third of the cases.

Continent urinary diversions in the exstrophy complex: why do they fail?
PURPOSE: Urinary continence is one of the primary goals in the surgical treatment of the patient with exstrophy. Children with inadequate bladder capacity, noncompliant or neuropathic bladder, or failed bladder neck reconstruction may require creation of a continent urinary reservoir to achieve continence. While initial success rates are excellent, some patients suffer persistent urinary incontinence, severely affecting their quality of life. The reasons for such failure and subsequent management were evaluated. MATERIALS AND METHODS: A retrospective database review was performed in 748 patients with the exstrophy complex. Patients with a history of failed continent urinary diversion with incontinence from the stoma or urethra were identified. Initial diagnosis, number of previous operations, reason for and time interval after surgery when failure occurred, and management strategies were evaluated. RESULTS: Of 92 patients undergoing continent diversion procedures 19 (21%) had failure initially (15 with classic and 4 with cloacal exstrophy). Four of the 19 patients underwent primary surgery at our institution and 15 were referred. The procedure initially performed was an intussuscepted nipple valve in 8 patients, an intussuscepted ileocecal valve in 1 and an ileal or sigmoid reservoir with appendiceal flap valve (Mitrofanoff) in 10. Main reasons for failure included de-intussusception and bladder neck incompetence. Mean followup after continence was achieved was 2.9 years (range 3 months to 10 years). These patients underwent up to 8 operations to achieve continence (mean 5). Most patients (79%) were successfully treated with either 1 (47%) or 2 revisions (32%), while 1 required 3 reoperations. Overall, 89 of 92 patients (97%) are currently continent, including those requiring medications and further surgical procedures, while 3 are still wet. CONCLUSIONS: Most patients with exstrophy with failure of continent urinary diversion have a long complicated surgical history. In this series incontinence from an intussuscepted nipple stoma was mostly due to de-intussusception. In patients with an initial Mitrofanoff stoma all incontinence occurred within the first few months postoperatively. Continence was achieved by either recreation of a Mitrofanoff stoma or bladder neck transection. Patients with a failed continent urinary diversion benefit from careful preoperative evaluation, meticulous surgical execution and persistent attempts to achieve continence.

Preservation of urinary continence and potency after cystoprostatectomy.
Between 1980-1989 a total of 349 patients underwent one-stage radical cystoprostatectomy and an orthotopic bladder substitution. 278 patients underwent the Camey I bladder replacement and in 71 patients a detubularized ileal loop was utilized (Camey II). 75 patients underwent a potency-sparing cystectomy (32 patients of the Camey I and 43 patients of the Camey II groups). All patients were followed at least one year and had continence and potency assessment. Among the patients who underwent the Camey I procedure, 66% achieved daytime continence and 21% night-time continence 6 months after surgery. One year after surgery 86% of patients had normal continence during the day and 47% was continent during the night. 14% of patients had episodes of day-time incontinence one year after surgery. Among the patients who underwent the Camey II bladder replacement 86% achieved day-time continence and 59% night-time continence 6 months after surgery. At one year after surgery 91% was continent during the day, 72% was dry during the night and only 9% had episodes of diurnal incontinence. Potency was achieved in 24 of 32 patients (75%) with the Camey I bladder substitution, and in 34 of the 43 patients (79%) with the Camey II bladder substitution. Our data demonstrate that excellent rates of continence and potency are achievable in the post-cystectomy population. Patients with the Camey II bladder replacement achieve continence earlier than patients with the Camey I bladder substitution. Diurnal continence is slightly better after the Camey II procedure, one year after surgery, but the difference is not statistically significant. Nocturnal continence is significantly better with the Camey II bladder substitution.

Does detubularization improve continence in bladder replacement?
Camey in the seventies promoted bladder replacement. In 1987, the French Association of Urology gave us the opportunity to review 729 Tubularized Ileocystoplasty (Camey operation) [1]. The day time continence was excellent or acceptable (mild stress incontinence) on 91% of the patients, the night time continence was excellent (no pads, no leakage) or acceptable (one pad or less than 3 wakes at night) for 44% of the patients (56% had to use a device). Since 1985, the detubularization attempted to improve the continence rate. Today, the review of the literature shows that day time continence has not changed and the night time continence improved less than 20% arising from 44% to 60%. Bladder replacement after prostatocystectomy has been proved to be superior to continent urinary diversion in patients whose urethral and external sphincter can be preserved. Day time continence is excellent in tubularized and detubularized bowel reservoirs. Night time continence, in 30 to 50% of patients, remains an unresolved problem also in detubularized low pressure reservoirs, even if they are of great capacity. The literature is therefore too optimistic when describing night time continence in 85% of the patients. These results are stated in spite of the absence of sensitivity in the neobladder, the loss of reflexic increase in sphincteric activity during bladder filling, and the low sphincteric tonus during sleeping. These optimistic results are due to lack of unanimous criteria for evaluating continence after bladder replacement and not taking into consideration as continence failure the abundant although not frequent nighttime incontinence. In order to improve continence, muscle reeducation and artificial sphincter implantation are the most adequate solutions.(ABSTRACT TRUNCATED AT 250 WORDS)

Does a continence educational brochure promote health-seeking behavior?
OBJECTIVE: This study reviewed whether participants who were given a continence education package, which included a Continence Educational Brochure (CEB), and who indicated that they were bothered by incontinence symptoms changed health-seeking behaviors about their incontinence problem because of being given the brochure. METHOD: This study used a descriptive and exploratory design. Participants were given the CEB and asked to read the information. They were also asked to complete a continence questionnaire and mail this back to the research team. Participants who indicated that they were bothered by a continence problem and consented to being interviewed were telephoned 2 to 3 months later. They were asked questions to determine their actions and progress in relation to managing their continence problem and whether the CEB had influenced their behavior. SETTING AND SUBJECT: A total of 631 participants (352 females, 55.8%; 279 males, 44.2%) from 4 rural and regional settings in Victoria, Australia, participated. Of this sample, 111 participants (78 females, 70.3%; 33 males, 29.7%) who reported that they were bothered by a continence problem were interviewed 3 months after being given the CEB. RESULTS: Two thirds of the total sample of participants (n=111) sought help for their continence problem. Approximately 70.3% (n=78) continued to have a continence problem. Of this group, 84.6% were still bothered by the continence problem and 65.4% had taken action to treat their incontinence. Forty-nine participants (44.1%) indicated that they had discussed the issue of bladder or bowel problems with someone directly because of this study or the information contained in the brochure. More than 94% of participants who remembered the CEB indicated that they believed the brochure would be helpful if given to other people. CONCLUSIONS: These findings suggest that the CEB prompted individuals to discuss their continence problem and in fewer cases to seek professional help. Given these findings, distribution of a continence education package is advocated as a continence health promotion strategy.

Malone antegrade continence enema for adults with neurogenic bowel disease.
PURPOSE: We describe the outcomes of adults with neurogenic bowel disease who underwent a Malone antegrade continence enema procedure with or without concomitant urinary diversion. MATERIALS AND METHODS: Consecutive adult patients with neurogenic bowel disease who underwent an antegrade continence enema procedure (continent catheterizable appendicocecostomy for fecal impaction) were retrospectively reviewed. RESULTS: Of the 7 patients who underwent an antegrade continence enema synchronous urinary procedure (ileal conduit, augmentation ileocystoplasty with continent catheterizable abdominal stoma or augmentation ileocystoplasty) was also performed in 6. Mean patient age was 32 years and mean followup was 11 months. Of the 7 patients 6 who self-administered antegrade continence enemas regularly were continent of stool per rectum and appendicocecostomy, using the appendicocecostomy as the portal for antegrade enemas. All 6 compliant patients reported decreased toileting time and improved quality of life. Preoperative autonomic dysreflexia resolved postoperatively in 3 patients. All urinary tracts were stable. In 4 patients 5 complications occurred, including antegrade continence enema stomal stenosis requiring appendicocutaneous revision (1), antegrade continence enema stomal stenosis requiring dilation (1), superficial wound infection (1), small bowel obstruction requiring lysis of adhesions (1) and urinary incontinence (1 who underwent continent urinary diversion). CONCLUSIONS: Patients with neurogenic bladder and bowel disease may benefit from antegrade continence enema performed synchronously with a urinary procedure. Antegrade continence enema may be indicated alone for neurogenic bowel. Patient selection is important.

Attempted nerve sparing surgery and age have a significant effect on urinary continence and erectile function after radical cystoprostatectomy and ileal orthotopic bladder substitution.
PURPOSE: We assessed factors influencing urinary continence and erectile function after radical cystoprostatectomy and ileal orthotopic bladder substitution. MATERIALS AND METHODS: Of 381 consecutive men undergoing radical cystoprostatectomy and ileal orthotopic bladder substitution between April 1985 and June 2003, 331 (87%) met the inclusion criteria and were enrolled in the analysis. Kaplan-Meier models and multivariate analysis applying Cox regression were used to evaluate factors influencing postoperative urinary continence and erectile function. RESULTS: In univariate analysis, attempted nerve sparing and age younger than 65 years were significantly associated with better daytime (p = 0.002 and p = 0.007, respectively) and nighttime continence (p = 0.036 and p = 0.005, respectively). In multivariate analysis the rate of daytime continence was significantly higher in patients with attempted nerve sparing (hazards ratio [HR] 1.4, 95% confidence interval [CI] 1.05-1.87) and nighttime continence was significantly better in patients younger than 65 years (HR 1.39, 95% CI 1.07-1.8). Daytime continence was significantly better (p <0.0001) and was achieved more quickly than nighttime continence (p <0.0001). The time to achieve daytime continence was shorter for patients with attempted nerve sparing (p = 0.012). In multivariate analysis erectile function recovered significantly more often in patients with attempted nerve sparing (HR 2.59, 95% CI 1.24-5.39) and in those younger than 65 years (HR 2.98, 95% CI 1.83-4.85). CONCLUSIONS: After radical cystoprostatectomy and ileal orthotopic bladder substitution, attempted nerve sparing and age younger than 65 years are associated with improved urinary continence. Attempted nerve sparing has the greatest impact on daytime continence and age has the greatest impact on nighttime continence. Attempted nerve sparing and younger age are both associated with more frequent recovery of erectile function.

Restoration of posterior aspect of rhabdosphincter shortens continence time after radical retropubic prostatectomy.
PURPOSE: Prolonged postoperative incontinence is a major drawback of RRP. Age, scars in the rhabdosphincter, nonnerve sparing surgery and postoperative sphincter insufficiency can cause temporary or definitive urinary incontinence. We believe that sphincter deficiency is the main cause of early incontinence. Urinary leakage results from the shortening of anatomical and functional sphincter length due to caudal retraction of the urethral sphincteric complex and disruption of the median posterior fibrous raphe. We describe a modification of the Walsh RRP that overcomes caudal retraction, reconstructs the posterior fibrous raphe and decreases time to continence. The primary study end point was early continence rate assessment. Long-term continence (1 year) and erectile function assessment were secondary end points. MATERIALS AND METHODS: To avoid caudal retraction of the urethrosphincteric complex, before completing the vesicourethral anastomosis the posterior semicircumference of the sphincter is joined to the residuum of Denonvilliers' fascia and fixed to the posterior bladder wall 1 to 2 cm cranial and dorsal to the new bladder neck. Vesicourethral anastomosis is subsequently performed with care taken not to involve the neurovascular bundles. A total of 161 patients with clinically confined disease underwent modified RRP (group 1). They were compared with a historical series of 50 patients who underwent standard RRP (group 2). Early continence was defined as no pad use but patients using 1 diaper were also considered continent. Continence, assessed prospectively as the number of pads daily, was evaluated 3, 30 and 90 days, and 1 year after catheter removal. The continence state was assessed by a multivariate logistic model. Erectile function was evaluated using the International Index of Erectile Function questionnaire preoperatively and after 18 months in patients younger than 65 years who underwent nerve sparing surgery. RESULTS: In group 1, 116 (72%), 127 (78.8%) and 139 patients (86.3%) were continent 3, 30 and 90 days after catheter removal compared with 7 (14%), 15 (30%) and 23 (46%), respectively, in group 2. One-year continence rates were 96% and 90%, respectively. Erectile function was similar in groups 1 and 2 (46% and 42%, respectively). Multivariate analysis showed that continence was significantly influenced by operation type, stage and patient age. CONCLUSIONS: Careful reconstruction of the posterior aspect of the rhabdosphincter markedly shortens time to continence.
