Long-term bladder, colorectal, and sexual functions after radical radiotherapy for urinary bladder cancer.

PURPOSE: To describe bladder, colorectal, and sexual dysfunctions among long time survivors after radical radiotherapy for urinary bladder cancer, and compare the results with a healthy control group. MATERIALS AND METHODS: We identified 261 patients who had received radical radiotherapy for bladder cancer in the period 1994-2001. Patients were treated with a CT-based three-field technique with 60 Gy in 2 Gy fractions, 5 fractions/week. Sixty-two patients were alive and candidates for the study. For comparison, 185 controls were selected from the Danish National Register. Information was collected in an interview based on the LENT SOMA tables and questions concerning changes in daily life following radiotherapy. RESULTS: Fifty-three patients (85%), median age 77 years (range 51-84) entered the study. Median follow-up time was 29 months (range 18-103 months). There were 63 controls (34%). Fourteen percent of the patients reported that radiotherapy had moderate to severe impact on their present bladder function. Compared with the control group, significantly more patients had dysuria, and urethral stenosis, and were using bladder catheter. Twenty-nine percent of the patients reported moderate to severe impact on their present bowel function. Significantly more patients had diarrhoea, fecal urgency and fecal incontinence, and were using antidiarrhoea medication and sanitary pads. Twenty-five percent of the patients reported moderate to severe impact on their present sexual function. Impotence and lack of sexual desire were significantly higher among the male patients. CONCLUSIONS: Following radical radiotherapy, most patients had a well functioning bladder, whereas 14% reported moderate to severe bladder dysfunctions. Due to the presence of bowel in the treatment field, radiotherapy is associated with considerable long-term intestinal side effects. Moreover, radiotherapy may result in sexual dysfunctions.

Initial results of salvage laparoscopic radical prostatectomy after radiation failure.

PURPOSE: We evaluated the feasibility of laparoscopic radical prostatectomy for recurrence after irradiation. MATERIALS AND METHODS: Since 2000, 7 patients with biological failure after irradiation (5 external beam radiation and 2 brachytherapy), and no metastasis on computerized tomography and bone scan underwent a transperitoneal laparoscopic radical prostatectomy according to the Montsouris technique. The left index finger was placed in the rectum to control the prostatorectal dissection. We call this procedure "finger assisted laparoscopy." RESULTS: Average operating time was 190 minutes (range 170 to 210), average blood loss was 387 cc (range 50 to 1,100) and no patient was transfused. Bladder catheter was removed after an average of 13 days because of the slower tissue healing after irradiation. No death or intraoperative complication occurred. There was no conversion to open surgery. Average postoperative stay was 6.4 days. Average followup was 11.2 months. Of the 7 patients 5 are continent (no pad day or night) and 2 have stress incontinence. All patients are impotent. No patient had urethral stenosis or lymphocele. Prostate specific antigen is lower than 0.1 ng/ml in 5 patients and higher in 2. CONCLUSIONS: Laparoscopic salvage radical prostatectomy after irradiation is feasible with no more morbidity than an open procedure. A longer followup is mandatory to evaluate its usefulness.

Anatomical and functional changes in the lower urinary tract following spontaneous vaginal delivery.

OBJECTIVE: To assess the incidence of urinary incontinence in pregnancy and after spontaneous vaginal delivery and its relation with changes in the static and dynamic function of the pelvic floor. DESIGN: The second part of a prospective longitudinal study. SETTING: University Hospital Groningen and Martini Hospital Groningen, the Netherlands. POPULATION: A cohort of 62 women before and after spontaneous vaginal delivery at term and 27 nulliparous non-pregnant controls. METHODS: Urinary incontinence was measured by a questionnaire and by a 24 hour pad test. The position and mobility of the urethrovesical junction were measured by perineal ultrasound and related to simultaneously measured abdominal pressure changes. Serial investigations were done at 38 weeks of gestation and at 6 weeks and 6 months after delivery. MAIN OUTCOME MEASURES: Urinary incontinence and its relation with the position of the urethrovesical junction at rest and with the mobility of the urethrovesical junction during Valsalva and during coughing, indicated by the displacement/pressure coefficient and with obstetric variables. RESULTS: After delivery, reported urinary incontinence was reduced from 26% at 38 weeks of gestation to 16% and 15% at 6 weeks and 6 months after delivery, respectively. Even lower rates were measured by the 24 hour pad test, which revealed a decrease from 14% at 38 weeks to 10% and 5% at 6 weeks and 6 months postpartum, respectively. Six weeks and six months after delivery, the angle of the urethrovesical junction at rest was significantly increased compared with the non-pregnant control women. Compared with the antenatal measurements, the displacement/pressure coefficients during coughing and during the Valsalva manoeuvre were significantly increased six weeks after delivery. Six months after delivery, only the coefficient for coughing was still significantly greater than the antenatal value and the value in the non-pregnant control group. No relations were found between urethrovesical junction measurements and obstetric variables and subjective or objective urinary incontinence parameters. CONCLUSION: Although pregnancy and spontaneous vaginal delivery significantly increased the degree of bladder neck descent during coughing, urinary incontinence, quite common during pregnancy, occurs less frequently postpartum.

[Recovery of urinary incontinence after retropubic radical prostatectomy. Results in 100 patients].

AIM OF THE STUDY: To shorten the time to recovery of full urinary continence after radical retropubic prostatectomy and to increase the postoperative continence rate. MATERIALS AND METHODS: One hundred and five consecutive patients were submitted to radical retropubic prostatectomy for prostate cancer, with curative intent, focusing our attention on three steps of the operation. First, to achieve a complete control of bleeding from the dorsal vein complex and to perform a minimal touch dissection of the urethral stump; second, to perform a conservative dissection of the bladder neck, and, third, to implement a vascular type, watertight, vesico urethral anastomosis. Continence was assessed 24 hours after catheter removal and at monthly follow up visits until full recovery and graded as dry if no dropping was visible and the patient was able to interrupt the urinary stream during micturition; stress incontinence, if any dropping was observed during abdominal strain between micturitions; and wet, if uncontrollable dropping occurred, and the number of pads needed per day recorded. RESULTS: At a median follow-up time of 18 months, range 6 to 30, a total of 87 of 100 evaluable patients (87%) resulted as dry; 10 patients (10%) resulted as having a variable degree of stress incontinence needing one to three pads per day, and 3 patients (3%) resulted as wet. In 41 of the 87 dry patients (47.1%) continence was achieved within the first day from catheter removal, and in a median time of 4 weeks, range 2 to 16 in the remaining 46 patients (52.9%). CONCLUSIONS: The results of total continence rate of the present study seem to compare to the recent literature except for the time to full recovery which is shorter; it is difficult to identify the contribution of each single surgical step.

A pilot study of factors influencing bowel function after colorectal anastomosis.

PURPOSE: This study was undertaken to assess subjective bowel function after anterior resection and to search for clinical characteristics that might affect the functional results. METHODS: A total of 70 patients answered a questionnaire concerning bowel function a median of 65 months after anterior resection, and 40 patients responded to the same questionnaire a median of 60 months after colonic resection. RESULTS: Median frequency of bowel movement per 24 hours was two (range, 0.2-9) after rectal resection and one (range, 0.4-6) after colonic resection (P < 0.001). Incontinence for loose stools (P < 0.01), need to wear a pad (P < 0.05), and need to return to the toilet after defecation (P < 0.05) was more common in the rectal resection group. In the latter group, advanced age, use of descending or transverse colon for anastomosis, and large amount of intraoperative bleeding was associated with fecal incontinence (P < 0.05). Preoperative radiotherapy was correlated with a high bowel frequency (P = 0.003). CONCLUSIONS: These data indicate that alterations of subjective bowel function frequently observed after colorectal anastomosis may be affected by both surgical technique and adjuvant radiotherapy.

Rectal hypersensitivity worsens stool frequency, urgency, and lifestyle in patients with urge fecal incontinence.

PURPOSE: Rectal sensory mechanisms are important in the maintenance of fecal continence. Approximately 50 percent of patients with urge incontinence have lowered rectal sensory threshold volumes (rectal hypersensitivity) on balloon distention. Rectal hypersensitivity may underlie the heightened perception of rectal filling; however, its impact on fecal urgency and incontinence is unknown. This study was designed to investigate the impact of rectal hypersensitivity in patients with urge fecal incontinence. METHODS: Prospective and retrospective audit review of all patients (n = 258) with an intact native rectum referred to a tertiary colorectal surgical center for physiologic investigation of urge fecal incontinence during a 7.5-year period. Patients with urge fecal incontinence who had undergone pelvic radiotherapy (n = 9) or rectal prolapse (n = 6) were excluded. RESULTS: A total of 108 of 243 patients (44 percent) were found to have rectal hypersensitivity. The incidence of anal sphincter dysfunction was equal (90 percent) among those with or without rectal hypersensitivity. Patients with urge fecal incontinence and rectal hypersensitivity had increased stool frequency (P < 0.0001), reported greater use of pads (P = 0.003), and lifestyle restrictions (P = 0.0007) compared with those with normal rectal sensation, but had similar frequencies of incontinent episodes. CONCLUSIONS: Urge fecal incontinence relates primarily to external anal sphincter dysfunction, but in patients with urge fecal incontinence, rectal hypersensitivity exacerbates fecal urgency, and this should be considered in the management and surgical decision in patients who present with fecal incontinence.

Management of recurrent rectal prolapse.

PURPOSE: Many operations have been described for the management of rectal prolapse. Despite an overall recurrence rate of greater than 15 percent, few reviews address how to deal with this problem. This report summarizes our experience with recurrent rectal prolapse and includes suggestions for reoperative management of failed repairs from both abdominal and perineal approaches. PATIENTS AND METHODS: Fourteen patients (3 male) ranging in age from 22 to 92 (mean, 68) years underwent operative correction of recurrent rectal prolapse. Average time from initial operation to recurrence was 14 (range, 6-60) months. Initial operations (before recurrence) were as follows: perineal proctectomy and levatorplasty (10), anal encirclement (2), Delorme's procedure (1), and anterior resection (1). Operative procedures performed for recurrence were as follows: perineal proctectomy and levatorplasty (7), sacral rectopexy (abdominal approach; 3), anterior resection with rectopexy (2), Delorme's procedure (1), and anal encirclement (1). Average length of follow-up was 50 (range, 9-115) months. RESULTS: No further episodes of complete rectal prolapse were observed during this period. Preoperatively, three patients were noted to be incontinent to the extent that necessitated the use of perineal pads. The reoperative procedures failed to restore fecal continence in any of these three individuals. One patient died in the postoperative period after anal encirclement from an unrelated cause. CONCLUSION: Surgical management of recurrent rectal prolapse can be expected to alleviate the prolapse, but not necessarily fecal incontinence. Perineal proctectomies can be safely repeated. Resectional procedures may result in an ischemic segment between two anastomoses, unless the surgeon can resect a previous anastomosis in the repeat procedure. Nonresectional procedures such as the Delorme's procedure should be strongly considered in the management of recurrent rectal prolapse if a resectional procedure was performed initially and failed.

Treatment of stress incontinence by vaginal cones: short- and long-term results and predictive parameters.

OBJECTIVE: To evaluate prospectively the short- and long-term results of treatment with vaginal cones for women with urinary stress incontinence and to assess predictive parameters. PATIENTS AND METHODS: Fifty women (mean age 49 years, range 28-76) with differing severities of stress incontinence (mean parity 2.4 and mean 60-min pad-test 20.7 g) were treated with cones for 15 min twice a day for 8 weeks. Treatment results were evaluated immediately after and at a mean of 3 years after the treatment. Parameters were analysed to determine those with predictive value for a successful outcome. RESULTS: Physiotherapy was assessed as being successful, i.e. a complete cure or a reduction of > 50% of the original severity, in seven patients (14%), while in 43 patients (86%) the treatment failed. After 3 years, 13 (30%) reported that the treatment was successful, 27 (61%) reported failure and four (9%) underwent surgery for stress incontinence. Those with lesser amounts of urinary loss and those with less frequent incontinence would be most likely to benefit from treatment with vaginal cones. CONCLUSION: The treatment had a low success rate and we recommend that the vaginal cones should be used only for those with a slight or moderate degree of stress incontinence.

Vaginal flap reconstruction of the urethra and vesical neck in women: a report of 49 cases.

PURPOSE: A retrospective study was done to evaluate the results of a 1-stage urethral reconstruction in women. MATERIALS AND METHODS: Of 49 consecutive women who presented with anatomical damage to the urethra or vesical neck 48 underwent urethral and/or vesical neck reconstruction with vaginal flaps. A Martius labial fat pad flap was used in 47 patients, a gracilis flap in 1 and an anterior bladder tube in 1. In 41 patients the anti-incontinence procedure consisted of a fascial pubovaginal sling placed over the labial fat pad flap without tension. In 5 patients a modified Pereyra operation was done and 1 underwent a Kelly plication. Followup ranged from 1 to 11 years. RESULTS: Postoperatively continence was obtained in 42 of 49 patients (87%). The initial procedure failed in 7 patients and a secondary procedure was successful in 6. Of the 5 initial patients who underwent a modified Pereyra operation 3 had postoperative stress incontinence and all were cured subsequently by a pubovaginal sling. CONCLUSIONS: A 1-stage vaginal flap reconstruction and pubovaginal sling procedure is effective in women with extensive vesical neck and/or urethral damage.

Post-robotic prostatectomy urinary continence: characterization of perfect continence versus occasional dribbling in pad-free men.

OBJECTIVES: To review and characterize two groups of men who report being pad-free after robot-assisted laparoscopic prostatectomy (RLRP): those with occasional incontinence and those with complete control. METHODS: The study included 106 out of a total of 195 men who underwent RLRP. Inclusion requirements were adequate follow-up and no-pad continence status. All patients completed self-administered American Urological Association symptom score (AUAss) and continence questionnaires and underwent measurement of peak urinary flow rates, postvoid residual volumes, and voided volumes (VV) before and 3 months after surgery. All data and standard clinical characteristics were entered prospectively into an electronic database. RESULTS: Two distinct groups reported wearing no pads: the "perfect" group (n = 32) reported never leaking, and the "imperfect" group (n = 74) reported occasional leakage but did not wear pads. Preoperatively, the "imperfect" group was older (62.2 versus 59 years) and had more urinary symptoms (all P < 0.05). Postoperatively, the "imperfect" group took longer to achieve a pad-free status (median 39.8 versus 19.3 days), had larger prostates (mean 50.9 versus 43.2 g), had lower VV (324 versus 405 mL), and more urinary symptoms (AUAss 7.4 versus 4.3; all P < 0.05). CONCLUSIONS: Sixty-nine percent of men who attain "pad-free continence" after RLRP have occasional urinary leakage. Preoperatively, these men are characteristically older and have larger prostates, AUAss, and bother scores. Postoperatively, the "imperfect" group takes longer to achieve pad-free status and has smaller bladder capacities and more urinary symptoms. These results suggest that an overactive detrusor is the likely contributing etiology.

Pubovaginal fascial sling for all types of stress urinary incontinence: long-term analysis.

PURPOSE: There is a lack of consensus regarding indications and long-term efficacy of the many surgical techniques for treating stress incontinence. Historically pubovaginal sling has been reserved for cases of intrinsic sphincter deficiency or prior surgical failure. Transvaginal needle and retropubic suspensions have been used mainly for sphincteric incontinence unassociated with intrinsic sphincter deficiency. We report the long-term results of pubovaginal sling for all types of stress incontinence. MATERIALS AND METHODS: A total of 251 consecutive women with all types of stress incontinence who underwent pubovaginal fascial sling by a single surgeon were retrospectively and prospectively reviewed. Patients were evaluated preoperatively with history, physical examination, standardized symptom questionnaire, voiding diary, pad test, uroflow, post-void residual urine, video urodynamics and cystoscopy. Postoperatively women with at least 1-year followup were assessed by an independent third party (J. R.) who had no prior knowledge of them, and who recorded the parameters of the questionnaire, examination with a full bladder, voiding diary, pad test, uroflow and post-void residual urine. RESULTS: Overall stress incontinence was cured or improved in 92% of the patients with at least 1-year followup (median 3.1 years, range 1 to 15). The majority of patients with postoperative incontinence had de novo (3%) or persistent (23%) urge incontinence. Permanent urinary retention developed in 4 patients (2%). CONCLUSIONS: Fascial pubovaginal sling is an effective treatment for all types of stress incontinence with acceptable long-term efficacy.

Porcine small intestinal submucosa as a percutaneous mid-urethral sling: 2-year results.

OBJECTIVE: To report the 2-year follow-up results on patients treated with a novel minimally invasive outpatient procedure for placing a mid-urethral sling, using porcine small intestinal submucosa (SIS). PATIENTS AND METHODS: Thirty-four women with urodynamic evidence of stress urinary incontinence (SUI, 19) or of SUI with a positive cough test (15) were treated. A curved ligature carrier was used to create a tract between bilateral suprapubic stab incisions and a 2-cm mid-urethral vaginal incision. A suture secured to each end of the SIS sling was placed through the eyelet of the ligature carrier. Extraction was used to position the sling at the mid-urethra, providing a backboard of support that was remodelled with ingrowth of the patient's autologous tissue. RESULTS: SUI was reportedly cured in 27 of the 34 women (79%) at the 2-year follow-up; three (9%) of those with no complete resolution were pleased with their results, because the improvement allowed them to wear an average one or fewer pads per day. One patient developed de novo urge incontinence. Three patients (9%) developed suprapubic inflammation at 10, 21 and 45 days after surgery; all resolved, but one had a recurrence of SUI. No prolonged retention, erosion or other complications were noted. CONCLUSIONS: Early results with the percutaneous mid-urethral placement of SIS are promising and potentially comparable with those after using synthetic minimally invasive slings.

Revision rate after artificial urinary sphincter implantation for incontinence after radical prostatectomy: actuarial analysis.

PURPOSE: We determined the actuarial revision rate for artificial urinary sphincters implanted in patients who were incontinent after radical prostatectomy. MATERIALS AND METHODS: We reviewed the records of 70 consecutive patients who were incontinent after radical prostatectomy and who underwent primary artificial urinary sphincter implantation at the University of Michigan between 1984 and 1999. Questionnaires were mailed to all patients with an indwelling device, and telephone calls were placed to those who did not respond to the mailing. Information about surgical revision and current continence status was obtained from chart review and questionnaire response. The Kaplan-Meier curves for actuarial freedom from operative revision were constructed. RESULTS: Of the 66 patients with available postoperative data 24 (36%) required reoperation at a mean followup of 41 months. The 5-year actuarial rate for freedom from any operative revision was 50%, and the corresponding rate for cuff revision was 60%. A single operative revision did not predispose the patient to further revision. Questionnaire data indicated a continence rate of 80% (range 0 to 2 pads). CONCLUSIONS: Approximately half of the patients who were incontinent after radical prostatectomy may expect to undergo operative revision within 5 years after artificial urinary sphincter implantation. Despite this high reoperation rate, an excellent level of continence is maintained.

Physiotherapy for persistent postnatal stress urinary incontinence: a randomized controlled trial.

OBJECTIVE: The aim of this study was to compare the effectiveness of multimodal supervised physiotherapy programs with the absence of treatment among women with persistent postnatal stress urinary incontinence. METHODS: This was a single-blind randomized controlled trial. Sixty-four women with stress urinary incontinence were randomly assigned to 8 weeks of either multimodal pelvic floor rehabilitation (n = 21), multimodal pelvic floor rehabilitation with abdominal muscle training (n = 23), or control non-pelvic floor rehabilitation (n = 20). The primary outcome measure consisted of a modified 20-minute pad test. The secondary outcome measures included a Visual Analog Scale describing the perceived burden of incontinence, the Urogenital Distress Inventory, the Incontinence Impact Questionnaire, and pelvic floor muscle function measurements. RESULTS: Two patients dropped out, leaving 62 for analysis. At follow-up, more than 70% of the women in the treatment groups (14/20 in the pelvic floor and 17/23 in the pelvic floor plus abdominal group) were continent on pad testing compared with 0% of women in the control group. Scores on the pad test, Visual Analog Scale, Urogenital Distress Inventory, and Incontinence Impact Questionnaire improved significantly in both treatment groups (all P <.002), whereas no changes were observed in the control group. Pelvic floor muscle function, however, did not improve significantly in either active group. CONCLUSION: Multimodal supervised pelvic floor physiotherapy is an effective treatment for persistent postnatal stress urinary incontinence.

The male sling for post-prostatectomy incontinence: mean followup of 18 months.

PURPOSE: We review our experience with 42 consecutive patients undergoing the bone anchored male sling procedure. MATERIALS AND METHODS: A retrospective chart review was performed, and complete data and followup were available in 38 of the 42 patients. Success was defined as wearing 1 thin pad or less per day, or social continence. Variables such as severity of incontinence, age, detrusor overactivity, previous artificial urinary sphincter, history of radiation and intraoperative flow pressures were analyzed for success and risk of failure. RESULTS: With a mean followup of 18 months (range 6 to 26), 39.5% (15 of 38) were considered a success (socially continent). A statistically significant trend in the degree of preoperative incontinence predicting success was identified. Social continence in mild, moderate and severe cases was achieved in 67%, 50% and 0%, respectively (p =0.001/95% CI). Only 15.8% of patients were completely dry and not wearing pads. Significant perineal pain was reported in the early postoperative period but resolved in all patients. Infection occurred in 3 patients with erosion found in 1. CONCLUSIONS: Although these results are not as encouraging as previous reports, carefully selected patients with mild to moderate incontinence are good candidates for the male sling. Patients with a history of radiation, previous artificial urinary sphincter or severe incontinence should be counseled about the higher risk of treatment failure. Patients should be informed of the possibility of progressive failure with time and the occurrence of significant perineal pain in the early postoperative period.

Long-term effect of pelvic floor muscle exercise 5 years after cessation of organized training.

OBJECTIVE: To evaluate clinically and urodynamically the effect of pelvic floor muscle exercise on genuine stress incontinence 5 years after cessation of a structured training program. METHODS: All 23 women who had participated in a 6-month intensive pelvic floor muscle exercise regimen participated in the follow-up study. Mean age was 50.7 years (range 30-70). The assessment included history by interview, use of subjective rating instruments (leakage index and social activity index), vaginal palpation, measurement of pelvic floor muscle strength by use of vaginal pressure measurement, cystometry, urethral pressure profiles during cough, and pad test with standardized bladder volume. RESULTS: Three of 23 women had been treated surgically. Sixteen (70%) were exercising the pelvic floor muscles once a week or more. This included two of the women treated surgically. Of the 20 women not treated surgically, 70% were satisfied and did not want further treatment. Fifteen of 20 (75%) did not show any visible leakage during cough, and 11 had positive closure pressure during cough. There was a statistically significant increase in the scores of the leakage index and the pad test (P < .05) but not on the social activity index (P = .09). Pelvic floor muscle strength was reduced from a mean of 22 cm H2O (95% confidence interval [CI] 17-26.9) to 19.1 (95% CI 13.2-24.9) (P = .113) during the 5-year period. CONCLUSION: There was a significant increase in incontinence measured by pad test and leakage index 5 years after cessation of organized pelvic floor muscle exercise. However, 75% showed no leakage during stress test, and 70% were satisfied with the condition. Seventy percent were exercising the pelvic floor muscles at least once a week, and pelvic floor muscle strength was maintained.

Periurethral fat injection in the treatment of recurrent genuine stress incontinence.

PURPOSE: We evaluated the efficacy, safety and mechanism of periurethral fat injection in the treatment of recurrent genuine stress incontinence. MATERIALS AND METHODS: Periurethral fat injections were performed in 26 patients for the treatment of recurrent genuine stress incontinence. A complete urogynecological study, including a 1-hour pad test, urodynamic studies and chain urethrocystography were done in each case and were repeated at least 3 months after operation. Each patient was followed for at least 12 months. RESULTS: Of 26 patients 13 (50%) were dry after operation and 4 (15.4%) showed improvement and were satisfied with the results of the operation, giving a total success rate of 65.4%. There were 6 cases of immediate postoperative minor complications (23%). Average volume of injected fat was 14.8 +/- 4.8 cc, which did not affect the success rate. Preoperative and postoperative chain urethrocystographic values for bladder neck descent in reference to the pubosacral tip line showed no statistical difference between successfully and unsuccessfully treated groups. Urodynamic studies in all cases showed no differences relating to operation. However, minimal urethral resistance increased from 0.122 +/- 0.061 to 0.205 +/- 0.134 (p = 0.023) in the treatment success group. This change was not demonstrated in the treatment failure group. CONCLUSIONS: Periurethral fat injection for the treatment of recurrent genuine stress incontinence is a simple technique that works by the increment of urethral resistance. It has an acceptable success rate without financial outlay for the injected material.

Is HCl duloxetine effective in the management of urinary stress incontinence after radical prostatectomy?

INTRODUCTION: Up to 70% of patients who undergo radical prostatectomy complain about urine leakage, but persistent stress incontinence 1 year after surgery affects <5% of them. HCl duloxetine is a dual serotonin and norepinephrine reuptake inhibitor that relieves the symptoms of stress urinary incontinence. The purpose of this study was to evaluate the efficacy of HCl duloxetine in the management of urinary incontinence after radical prostatectomy and its impact in urodynamic parameters such as maximal urethral closure pressure (MUCP), abdominal leak point pressure (ALPP) and retrograde leak point pressure (RLPP). MATERIAL AND METHODS: The study included 18 men with stress urinary incontinence 12 months after radical prostatectomy. All underwent a pad test to quantify the degree of urine loss and a urodynamic evaluation before and after a three month treatment with HCl duloxetine. The intrinsic sphincter was evaluated by ALPP and RLPP and the striated sphincter by MUCP. RESULTS: At the pretreatment evaluation the mean ALPP was 52.1 cm H(2)O, the mean MUCP was 52.5 cm H(2)O and the mean RLPP was 43.1 cm H(2)O. After 3 months of HCl duloxetine treatment the mean ALPP was 59.1 cm H(2)O, the mean MUCP was 67.3 cm H(2)O and the mean RLPP was 45.1 cm H(2)O. There was a statistically significant correlation among RLPP, MUCP and ALPP before treatment. After HCl duloxetine treatment there was significant correlation between RLPP and ALPP. CONCLUSION: The use of HCl duloxetine results in mild increase of MUCP and in significant reduction of urine loss. Its action on the extrinsic sphincter does not provide a complete treatment option for postprostatectomy incontinence.
