The relevance of preoperative cystometrography in patients with benign prostatic hyperplasia: correlating the findings with clinical features and outcome after prostatectomy.

Preoperative water cystometrograms in 437 patients with benign prostatic hyperplasia (BPH) were examined in a retrospective study. The cystometrographic results were analyzed regarding the preoperative clinical features: patient age, presence or absence of urinary incontinence, history of urinary retention and rate of residual urine. The prognostic value in improvement in voiding difficulty and postoperative urinary incontinence was also analyzed at 1 and 6 months after elective prostatectomy. Subjective symptoms of the patients were the primary reasons for prostatectomy, the majority of which were performed by a single competent resectionist (K. T.) who evaluated the outcome but was blinded to the cystometric findings. Of these patients 263 (60.2%) had detrusor instability (group 1), while 174 did not (group 2). Vesical denervation supersensitivity to bethanechol chloride was noted in 47 of 375 patients (12.5%). The difference in clinical features was significant between the 2 groups, with group 1 showing older patient age (p < 0.01), and a greater incidence of urinary incontinence (p < 0.001) and retention (p < 0.001). The difference between groups 1 and 2 in mean bladder capacity (p < 0.01), compliance (p < 0.01) and a greater positive rate of vesical denervation supersensitivity (p < 0.001) was also significant. The clinical and cystometrographic parameters studied worsened with advancing patient age. Although the majority of the patients (94.7%) were relieved of obstructive symptoms after transurethral prostatectomy (6 months later), 113 (25.9%) were not at 1 month. Compared to 324 patients with early improvement (74.1%), those without improvement at 1 month were characterized by older age (p < 0.01), greater prevalence of preoperative incontinence (p < 0.05), retention (p < 0.01), greater residual rate (p < 0.05), a less compliant bladder (p < 0.01) and a higher positive rate of vesical denervation supersensitivity (p < 0.05). Cystometrographic findings, however, had no relevance to late (6 months) outcome of voiding difficulty. On the other hand, postoperative incontinence was noted in 100 patients (22.9%) at 1 month after transurethral prostatectomy, with the majority having episodes similar to those experienced preoperatively (70.0%) as well as detrusor instability (87.0%). They also were older (p < 0.01), and had a less compliant bladder (p < 0.01) and a higher positive rate of vesical denervation supersensitivity (p < 0.01) than did continent patients. Only 18 elderly patients (4.1%) remained incontinent 6 months later, all with a less compliant (p < 0.01) and more unstable (p < 0.01) bladder initially. The genesis of this detrusor dysfunction was believed to be aging in male patients, in whom BPH evolves and progresses. In conclusion, preoperative cystometrography in patients with BPH is valuable in that it correlated well with the clinical features and it can predict to some extent the outcome of obstructive symptoms and urinary incontinence after transurethral prostatectomy.

Radical prostatectomy as a monotherapy for locally advanced (stage T3) prostate cancer.

Within a prospective protocol initiated in 1977, 100 patients with locally extensive prostate cancer (stage T3, 1982 tumor, nodes and metastasis classification) were treated by pelvic node dissection and radical prostatectomy as monotherapy. Adjuvant treatment was not given until disease progression. Radical prostatectomy, except for 3 young patients with a single micrometastasis, was not done if positive lymph nodes were found at frozen section. Six patients had positive lymph nodes at permanent sections but not at frozen section. Average followup was 43.9 months (range 1 to 155 months). Histological grade was determined according to the Mostofi system. Progression was determined biochemically (prostate specific antigen elevation) and clinically by evidence of metastatic disease, either histologically proved or evidenced as new hot spots on bone scan or chest x-rays. Of the 100 patients 41 did not undergo radical prostatectomy: 39 because of positive lymph nodes and 2 because of evidence of a stage pT4 tumor at surgical exploration. Of those 59 patients who underwent radical prostatectomy 9 had positive lymph nodes, while 2 had stage pT4, 39 stage pT3 and 9 stage pT2 tumors. Only 1 of the 9 patients with lymph node metastases is free of biochemical or clinical progression. Disease also progressed in both stage pT4, 27 of 39 stage pT3 and none of the 9 stage pT2 cases. A total of 22 patients was free of clinical or biochemical progression. Clinical progression was evidenced in approximately half of the cases as distant and local progression. Data on stage T3 disease were compared to those of 129 patients with stages T0 to T2 disease. There was a significant difference in interval to clinical progression for these 2 groups (p = 0.001). However, if grade 3 cases were excluded from the stage T3 group, this difference disappeared. Prognostic factors analyzed were pretreatment and posttreatment grade, pretreatment prostate specific antigen and prostatic acid phosphatase levels, positive margins, seminal vesicle invasion and nodal status. The analysis allows one to identify groups of patients who may benefit and others who certainly do not benefit from radical prostatectomy in this disease category. In the latter group effective adjuvant treatment is urgently indicated.

The value of laparoscopic lymphadenectomy in conjunction with radical perineal or retropubic prostatectomy.

A total of 76 men with clinically localized prostate cancer underwent surgical treatment at our institution during an 11-month period. Of the patients 26 underwent staging laparoscopic pelvic lymph node dissection followed by radical perineal prostatectomy (group 1), 24 underwent laparoscopic pelvic lymph node dissection and radical retropubic prostatectomy (group 2), and 26 underwent standard open lymphadenectomy and radical retropubic prostatectomy (group 3). Group 1 patients experienced statistically significantly less average blood loss (576 +/- 360 cc) than either group 2 (1,275 +/- 686.8) or 3 (1,100 +/- 459, p < 0.001). Hospital stay was also significantly less in group 1, with a mean of 4.6 +/- 1.9 days compared to 9.6 +/- 4.6 and 7.25 +/- 2.06 days for groups 2 and 3, respectively (p < 0.001). Our study supports the combination of laparoscopic pelvic lymph node dissection and radical perineal prostatectomy as a potentially less morbid approach to the surgical treatment of prostate cancer. However, no benefit was found for laparoscopic staging in patients before radical retropubic prostatectomy.

The effect of intermittent pneumatic compression devices on intraoperative blood loss during radical prostatectomy and radical cystectomy.

Intermittent pneumatic compression devices are a widely used, effective and presumed risk-free method of deep venous thrombosis prophylaxis, presumably by increasing peak venous blood velocity, and stimulating local and systemic fibrinolysis. We investigated whether intermittent pneumatic compression devices had any effect on intraoperative blood loss or transfusion during radical pelvic urological surgery. To our knowledge no previous study has addressed these issues. Records were reviewed for patients undergoing radical retropubic prostatectomy or radical cystectomy with diversion from 1985 to 1990. A total of 91 cases was reviewed: 38 radical retropubic prostatectomies and 53 radical cystectomies with diversion (34 male and 19 female patients). There were 59 patients with intermittent pneumatic compression devices (29 radical retropubic prostatectomies and 30 radical cystectomies with diversion) and 32 without intermittent pneumatic compression devices (9 radical retropubic prostatectomies and 23 radical cystectomies with diversion). Intraoperative blood loss and transfusions were calculated for each group with and without intermittent pneumatic compression devices. No clinically apparent lower extremity deep venous thrombosis or pulmonary embolus was diagnosed in any patient. For the group with intermittent pneumatic compression devices mean intraoperative blood loss was 2,541 ml. (range 700 to 8,850) versus 1,807 ml. (range 450 to 5,100) without a device, for a statistically significant difference of 734 ml. (p = 0.005). When 5 patients with excessive intraoperative blood loss (more than 5,000 ml.) were excluded the statistically significant difference was maintained. When comparing radical retropubic prostatectomy and radical cystectomy with diversion, with and without intermittent pneumatic compression devices, blood loss was greater for the group with a device for each procedure. Differences in intraoperative blood loss were independent of sex or tumor stage. Intraoperative transfusions were increased by approximately 0.6 units per patient with the device. Our study suggests that intermittent pneumatic compression devices may increase blood loss during a radical pelvic operation.

Is tumor volume an independent predictor of progression following radical prostatectomy? A multivariate analysis of 185 clinical stage B adenocarcinomas of the prostate with 5 years of followup.

Tumor volume has been shown to be proportionate to Gleason grade, capsular penetration, seminal vesicle invasion, lymph node metastases and capsular margins of resection. Because these variables are often interrelated, it is crucial to determine which of these parameters provides independent prediction of prognosis in prostate cancer. The current study analyzed 185 men who underwent radial retropubic prostatectomy for clinical stage B adenocarcinoma of the prostate. Patients with seminal vesicle invasion or lymph node metastases were excluded, since these findings are almost invariably associated with progression. All patients were followed for a minimum of 5 years after radical prostatectomy. Only 2 men received postoperative adjuvant therapy. At 5 years after radical prostatectomy 58 men (31%) experienced progression, defined by either an elevated postoperative serum prostate specific antigen level, local recurrence or distant metastases. Although by themselves capsular penetration, tumor volume and per cent of the prostate involved by tumor predicted progression, in a stepwise regression analysis they did not provide independent prognostic information. In this multivariate analysis Gleason score was the best predictor of progression (p < 0.0001); surgical margin was the only other variable that enhanced prediction, although it was less influential than grade (p = 0.018). This strong predictability provided by Gleason score was all the more impressive given the relatively few patients in our study with either low or high grade tumor. Although an accurate preoperative assessment of tumor volume remains desirable for the management of patients with prostate cancer, our study demonstrates that measurement of tumor volume in radical prostatectomy specimens need not be performed as part of the routine pathological analysis of radical prostatectomy specimens, since it does not provide additional information beyond that of Gleason score and the status of capsular margins.

Radical prostatectomy: the pros and cons of the perineal versus retropubic approach.

Radical prostatectomy is frequently recommended for the treatment of localized adenocarcinoma of the prostate. The use of the perineal versus the retropubic approach is mostly dependent upon the experience of the individual surgeon. This study was performed to evaluate the short-term differences between the 2 operations. Between 1988 and 1989, 173 patients were identified with organ confined prostate cancer (stage A or B) who were treated with radical prostatectomy. Of this total population 122 patients underwent radical perineal prostatectomy (group 1) and 51 patients underwent radical retropubic prostatectomy (group 2). The median estimated blood loss for group 1 was 565 cc and for group 2 it was 2,000 cc (p less than 0.001). Group 1 received a median of 0 units of blood during hospitalization, while group 2 received a median of 3 units of blood (p less than 0.001). The total operative time was slightly shorter for group 1 but the anesthesia time was similar for both patient populations. There was no difference in the incidence of positive surgical margins, and in in-hospital and long-term complication rates between the 2 groups. In light of these significant findings it is our belief that the radical perineal prostatectomy is an excellent approach for the treatment of adenocarcinoma of the prostate.

Further study of the increased mortality following transurethral prostatectomy: a chart-based analysis.

Previous studies using large administrative databases found an elevated relative risk of reoperation and death after transurethral resection of the prostate compared to open prostatectomy. To investigate whether differences in case-mix unmeasured by administrative data explained this finding, we reviewed the charts of 485 patients who had undergone prostatectomy (236 open and 249 transurethral) at the Health Science Centre, Winnipeg, Manitoba, Canada between 1974 and 1980. Data from patient histories, physical examinations and laboratory evaluations were abstracted and used to control for case-mix in models comparing the rates of reoperation and mortality after transurethral versus open prostatectomy. Several models were specified. In all models the relative risk of dying after transurethral prostatectomy remained elevated (1.36 to 1.89), as did the risk for reoperation (3.62). A prospective trial is needed to establish the relative safety and effectiveness of transurethral and open prostatectomy.

Post-prostatectomy urinary incontinence: response to behavioral training.

Urinary incontinence after prostatectomy can be psychologically and socially disabling. We reviewed our experience with 27 patients who were incontinent between 5 and 198 months after either radical retropubic, total perineal or transurethral prostatectomy. These patients were entered into our bladder behavior clinic, which was administered by nursing staff with physician supervision. Patients were strongly encouraged to discontinue the incontinence devices, and were then evaluated for the type and extent of incontinence. Perineal exercises were demonstrated in detail, tested for their correct use via simultaneous rectal and abdominal examination, and applied to the pattern of incontinence. Patients were evaluated frequently for compliance and their progress was followed with instruction repeated as needed. Pharmaceutical agents were not used. Among the 24 patients evaluable over-all improvement in the number of incontinent episodes was 56.6% (p less than 0.001). Two patients (8.3%) achieved total continence, 10 (42%) improved greatly, 4 showed moderate improvement and 8 (33%) showed essentially no change. Transurethral and perineal prostatectomy patients improved by 74 and 61%, respectively, versus only 33% in the radical retropubic group (p = 0.14). In addition, patients who previously underwent transurethral resection before total prostatectomy did worse (18%) than did those who did not (67%). We conclude that a significant number of patients who are incontinent after prostatectomy (especially those without a prior transurethral resection) can improve dramatically with a behavioral training program that provides a strong support system.

Prostate specific antigen and local recurrence after radical prostatectomy.

We evaluated the location of recurrent disease in 63 patients with carcinoma of the prostate who had abnormal levels of prostate specific antigen (greater than 0.4 ng./ml., Tandem-R assay) 6 to 240 months after radical prostatectomy but who were otherwise considered to be without evidence of disease. The evaluation involved physical examination including digital rectal examinations by 3 urologists, isotopic bone scans, computerized tomography scans of the abdomen and pelvis, cystoscopy, and random needle biopsies of the urethrovesical anastomotic area. In 6 patients metastatic disease to the bone and/or lymph nodes was found and local prostate cancer was discovered in 5. Among 57 patients without evidence of disease by the usual methods of evaluation needle biopsies of the anastomosis revealed local disease in 42%. No local disease was discovered in 30 post-radical prostatectomy patients with normal prostate specific antigen levels. There was a wide range of transrectally palpable contours after radical prostatectomy in patients with and without elevated prostate specific antigen levels. We conclude that prostate specific antigen but not digital rectal examination is an excellent early indicator of possible local recurrence after radical prostatectomy. Whether the prevalence of local disease after radical prostatectomy using prostate specific antigen levels and needle biopsies of the anastomosis is greater than heretofore has been appreciated will require further study.

The effect of radiation therapy after radical prostatectomy in patients with elevated prostate specific antigen levels.

We analyzed the effects of pelvic radiation therapy given to patients who had an elevated prostate specific antigen level after radical prostatectomy. Among men who previously received adjuvant radiation therapy and had appropriately stored serum 15 had elevated prostate specific antigen levels after radical prostatectomy but before radiation therapy. After radiation therapy the prostate specific antigen level decreased by more than 50% in 80% and to female levels in 53% of the patients. We also prospectively treated 29 men who had increasing levels of prostate specific antigen 9 to 95 months after radical prostatectomy but who were otherwise without evidence of disease by the usual criteria. However, 19 of the patients had local disease as evidenced by random needle biopsy of the urethrovesical anastomosis. Complications of radiation therapy were minimal and maximal prostate specific antigen decrease occurred by 6 months after treatment. In 82% of the patients prostate specific antigen levels decreased by more than 50% and in 43% they decreased to female levels. Female levels were achieved after radiation therapy given many years postoperatively even in stage D1 cancer patients but some of the patients subsequently had increasing prostate specific antigen levels. These data suggest that local-regional disease may be the only site of disease persistence after radical prostatectomy in some of the patients who subsequently have distant metastasis. We conclude that radiation therapy after radical prostatectomy can cause elevated prostate specific antigen to decrease to undetectable levels in many patients but the durability and ultimate therapeutic value of this effect are unknown.

Role of nerve-sparing radical prostatectomy for clinical stage B2 prostate cancer.

To examine the role of nerve-sparing radical prostatectomy in patients with clinical stage B2 prostate cancer we reviewed the first 77 such patients in our series since we adopted the nerve-sparing technique. A total of 47 patients (61%) underwent bilateral and 26 (34%) underwent unilateral nerve-sparing prostatectomy, while in 4 (5%) both neurovascular bundles were resected. Among the patients followed for 12 months 27 of 41 (66%) treated with bilateral and 7 of 19 (37%) treated with unilateral nerve-sparing prostatectomy had potency preserved. With the strict clinicopathological criteria of organ-confined tumor, that is intracapsular tumor with negative surgical margins and undetectable postoperative prostate specific antigen levels, complete tumor excision was achieved in 17 patients (36%) treated with bilateral and 7 of 26 (27%) treated with unilateral nerve-sparing prostatectomy. All patients in whom both neurovascular bundles were resected had pathological stage C or D1 disease. Of the 24 patients who had complete tumor excision by the strict criteria only 15 (19.5% of the 77 preoperatively potent patients) had potency preserved. Of these patients 19 had microscopically positive margins without seminal vesicle invasion (pathological stage C1) with undetectable postoperative prostate specific antigen levels. In addition, 4 patients had seminal vesicle involvement with negative surgical margins and undetectable postoperative prostate specific antigen levels. If these patients also are considered as having complete tumor excision, there was an over-all complete tumor excision rate of 61% (47 of 77), of whom 25 (32% of the 77 patients) had preservation of potency. Ten patients with clinical stage B2 tumor whose potency was preserved had histological and serological evidence of incomplete tumor excision. Of 53 patients with pathological stage C1 disease 9 (17%) had margins positive only in the regions of the neurovascular bundles. Preoperative prostate specific antigen and acid phosphatase levels, and findings on transrectal ultrasonography failed to predict accurately which patients had extracapsular tumor extension. Patients with poorly differentiated tumors and/or bulky disease on rectal examination had a higher incidence of extracapsular extension and positive margins. We conclude that in the majority of potent patients with clinical stage B2 prostate cancer not all of the goals of nerve-sparing radical prostatectomy are realized.(ABSTRACT TRUNCATED AT 400 WORDS)

Morbidity of radical perineal prostatectomy following transurethral resection of the prostate.

Radical prostatectomy in patients who have had prior transurethral resection of the prostate has been reported to result in significant morbidity. From 1974 to 1982, 30 patients who had had previous transurethral resection of the prostate underwent radical perineal prostatectomy for localized prostatic cancer. Operative time and blood loss were similar to a group of patients who had not had prior transurethral resection of the prostate. Over-all, 3 patients (10 per cent) had total incontinence and 3 (10 per cent) had stress incontinence requiring a pad or device. No patient undergoing radical prostatectomy less than 4 weeks or more than 4 months after transurethral resection of the prostate had postoperative incontinence. When radical perineal prostatectomy was performed between 4 weeks and 4 months after transurethral resection of the prostate the incidence of incontinence was 50 per cent. Five patients experienced prolonged perineal urinary drainage, all but 1 of whom healed spontaneously. Of the 6 patients with incontinence 3 had prolonged drainage. No patient had a rectal injury and there was no operative mortality. Two patients died without cancer and 1 has evidence of disease recurrence. We conclude that radical prostatectomy may be performed safely with acceptable morbidity following transurethral resection of the prostate and that if 4 weeks has elapsed since resection it might be advantageous to wait 4 months before performing radical surgery to lessen the risk of incontinence.

Sexual potency after radical prostatectomy.

Systematically acquired data on preservation or loss of sexual potency after radical prostatectomy have not been reported frequently. Our retrospective study is based on a review of the hospital records of 62 patients who underwent radical prostatectomy between 1968 and 1978. No notation as to preoperative potency was found in the records of 74 per cent of the patients. Of 14 patients who affirmed preoperative potency 6 (43 per cent) reported normal erections and resumption of sexual intercourse postoperatively. The mean of these 6 men was significantly less than the group as a whole (p les than 0.01). It is urged that an adequate sexual history be elicited before any prostatic operation, and certainly in advanced of radical prostatectomy. It is suggested that sexual potency may be retained after radical prostatectomy far more often than has been presumed previously. Thus, urologists should be aware of the sexual interests and competency of their aging male patients, and encourage continuation of sexual activity after radical prostatectomy.

Analysis of the mechanism of discrepant nuclear morphometric results comparing preoperative biopsy and prostatectomy specimens.

OBJECTIVES: To explore the mechanism for the differing nuclear morphometric results between needle biopsy and surgical specimens of the prostate. METHODS: In experiment 1, a comparison of mean nuclear area (MNA), volume-weighted mean nuclear volume (MNV), and form factor (FF) for prostatic epithelial cells was performed between preoperative needle biopsy and prostatectomy specimens from 5 patients with benign prostatic hyperplasia (BPH). In experiment 2, a scheduled, sequential ex vivo needle sampling from the enucleated prostates (at 0, 2, 6, and 24 hours after surgical resection) was also performed for 7 patients with BPH. The prostatectomy specimens were left unfixed for 2 hours until the second needle sampling was done. Nuclear morphometric parameters were measured on the needle-sampled as well as on the prostatectomy specimens. RESULTS: MNA, MNV, and FF of BPH cells measured on preoperative biopsy specimens were smaller than those of surgical specimens in all 5 of the cases. The results of nuclear morphometry on the materials obtained by ex vivo needle sampling of prostates before and during fixation revealed that the MNA, MNV, and FF for BPH cells of 0-hour specimens were significantly smaller than those for needle samples at 2, 6, and 24 hours after surgical resection as well as those for prostatectomy specimens. CONCLUSIONS: The present study provided further evidence that the ischemic damage caused by delayed fixation could result in a substantial change of the nuclear morphology of prostate cells. An immediate start, as well as a rapid completion, of the fixation procedure seems critical for an accurate nuclear morphometry of prostatectomy specimens.

Prognostic significance of Gleason score 3+4 versus Gleason score 4+3 tumor at radical prostatectomy.

OBJECTIVES: To determine the clinical significance of Gleason score 3+4 versus 4+3 on radical prostatectomy. METHODS: Of 2390 men who underwent radical prostatectomy by a single surgeon, 570 had Gleason score 7 tumors without lymph node metastasis, seminal vesicle invasion, or tertiary Gleason pattern 5. Patients were evaluated for biochemical recurrence (prostate-specific antigen progression) and distant metastases. RESULTS: Eighty percent of patients had Gleason score 3+4, 20% had 4+3. The rate of established extraprostatic extension at radical prostatectomy for Gleason score 3+4 and 4+3 tumors was 38.2% and 52.7%, respectively (P = 0.008). With a mean follow-up of 4.6 years for men without progression, Gleason score 4+3 tumors had an increased risk of progression independent of stage and margin status (P <0.0001). The 5-year actuarial risk of progression was 15% and 40% for Gleason score 3+4 and 4+3 tumors, respectively. The mean time to progression was 4.4 years for Gleason score 3+4 tumors and 3.2 years for Gleason score 4+3 tumors. We stratified the patients into four prognostic groups on the basis of organ-confined status, margin status, and Gleason score (3+4 versus 4+3). The 5-year actuarial risk of progression was 10%, 35%, 45%, and 61%, with 10-year progression rates of 29%, 42%, 69%, and 84%, for the four groups. 3.9% of patients with Gleason score 3+4 and 10. 5% with Gleason score 4+3 tumors developed metastatic disease within a mean of 5.7 and 5.6 years, respectively. A Gleason score of 4+3 versus 3+4 was predictive of metastatic disease (P = 0.002) but not local recurrence. CONCLUSIONS: Gleason score 7 tumors are heterogeneous in their biologic behavior. The differences in prognosis for patients with Gleason scores 3+4 and 4+3 tumors at radical prostatectomy are significant. Although the assessment of the percentage of pattern 4 at radical prostatectomy is not likely to be reproducible, the distinction between Gleason score 3+4 and 4+3 should be easier for pathologists to perform.

Anastomotic strictures following radical prostatectomy: insights into incidence, effectiveness of intervention, effect on continence, and factors predisposing to occurrence.

OBJECTIVES: To examine the incidence, effectiveness of intervention, effect on continence, and factors predisposing to the occurrence of anastomotic strictures following radical retropubic prostatectomy. METHODS: Between January 1994 and June 1999, 753 radical retropubic prostatectomies were performed by a single surgeon. Anastomotic strictures were managed by dilatation followed by a self-catheterization regimen. Dilatations were repeated unless more than three dilatations were required over a 9-month interval. A control group representing a randomly selected group of men who did not develop anastomotic strictures was identified. The largest width of the midline vertical abdominal scar was measured. RESULTS: Of the 753 radical retropubic prostatectomies, 36 (4.8%) developed an anastomotic stricture. The mean time interval between the surgical procedure and diagnosis of the stricture was 4.22 months. Of the 26 cases of anastomotic strictures with at least 1-year follow-up, 24 (92.3%) were managed successfully by dilatations alone. No baseline characteristics before surgery were associated with the development of a stricture. The maximal scar width was the only factor that was associated with the development of a stricture in this study. Men with a maximal scar of greater than 10 mm were eight times more likely to develop strictures than men with smaller scars. The percentage of men who required protective pads 1 year following radical retropubic prostatectomy in the control and stricture groups was 12.5% and 46.2%, respectively. CONCLUSIONS: Anastomotic strictures are relatively rare following radical prostatectomy and have a negative effect on the development of continence. Most men are successfully managed with dilatations alone. The development of anastomotic strictures in some men appears to be related to a generalized hypertrophic wound-healing mechanism.

Routine cystoscopy before radical prostatectomy: is it justified?

OBJECTIVES: The extent of the required preoperative workup of patients who are candidates for radical prostatectomy is still controversial. Traditionally, cystoscopy has been reserved only for those patients who present with hematuria. However, several investigators have reported significant incidental cystoscopic findings among these patients and advocated the routine use of cystoscopy before radical prostatectomy. In view of the conflicting recommendations, we elected to assess the role of routine cystoscopy in a series of patients with prostate cancer at our institute. METHODS: We retrospectively reviewed the cystoscopic findings of 225 consecutive patients with organ-confined prostate carcinoma scheduled for radical prostatectomy. Rigid cystoscopy was performed before surgery either in an outpatient setting or on the operating table just before the operation. RESULTS: Significant cystoscopic findings were noted in 3 (1.3%) of 225 patients. These included a bladder stone in 1 patient, superficial bladder tumor in 1 patient, and a post-sphincteric urethral polyp containing prostatic adenocarcinoma in a third patient. This polyp was resected transurethrally and the patient was treated thereafter with irradiation because of local extension. None of the 3 patients had microscopic hematuria on urinalysis to suggest the findings. Cystoscopy was uneventful in all patients, apart from occasional mild hematuria. CONCLUSIONS: These results show that the treatment of patients who were candidates for radical prostatectomy was affected by the findings of preoperative cystoscopy in less than 1% of the cases. We believe that in view of the low yield of cystoscopic findings in these patients, in an era in which cost effectiveness is a major issue, the routine use of cystoscopy before radical prostatectomy is not justified.

Prospective patient-reported continence after laparoscopic radical prostatectomy.

OBJECTIVES: To perform a prospective study using confidential patient-completed questionnaires about their urinary habits before and after laparoscopic radical prostatectomy. Published reports on urinary continence after radical prostatectomy vary depending on the definitions of urinary continence and methods of data collection. METHODS: From May 1998 to February 2000, 228 men underwent laparoscopic radical prostatectomy for clinically localized prostate cancer. The patients were given questionnaires before surgery and at 1, 3, 6, and 12 months postoperatively. RESULTS: Before surgery, no patient reported incontinence. At 1, 3, 6, and 12 months postoperatively, perfect diurnal urinary control (no pads, no leakage at all) was reported in 9.9%, 28.6%, 57.4%, and 56.8% of patients, respectively. No pads were used in 18.8%, 58.4%, 68.9%, and 78.4% at 1, 3, 6, and 12 months, respectively. No patient reported use of more than 1 pad daily at 6 months of follow-up. CONCLUSIONS: Continence after laparoscopic radical prostatectomy is comparable to the results after traditional radical retropubic prostatectomy. Ongoing use of the laparoscopic route for treating clinically localized prostate cancer is warranted.
