Evolution of the presentation and pathologic and biochemical outcomes after radical prostatectomy for patients with clinically localized prostate cancer diagnosed during the PSA era.

OBJECTIVES: To demonstrate the evolution of the clinical presentation and pathologic and biochemical outcomes for patients with clinically localized prostate cancer treated with radical prostatectomy during the prostate-specific antigen (PSA) era. METHODS: One thousand fifty-nine consecutive men treated with radical prostatectomy from January 1989 to December 2000 comprised the study cohort. A chi-squared metric was used to compare the proportions of patients during three intervals (1989 to 1992, 1993 to 1996, and 1997 to 2000) by categories of PSA level, biopsy Gleason score, clinical T stage, percent positive biopsy cores, age, and risk group, as well as pathologic T stage, Gleason score, margin status, and lymph node status. Actual 2-year PSA recurrence-free survival rates are reported for patients with a minimal follow-up of 24 months, stratified by the interval and preoperative risk group. RESULTS: There was a significant shift in the preoperative characteristics toward younger patients (P <0.0001) with nonpalpable disease (P <0.0001), lower PSA levels (P <0.0001), fewer percent positive biopsies (P <0.0001), and lower preoperative risk group classification (P <0.0001). Pathologically, a significant downward stage migration was found toward organ-confined disease (P <0.0001) and improvement in surgical margin status (P <0.001). The actual 2-year PSA recurrence-free survival rates improved during the three intervals spanning the PSA era from 60% to 78% and 82% (P <0.0001). CONCLUSIONS: With the introduction of serum PSA as a screening tool, we have noted an evolution toward a lower pathologic stage, grade, and improved PSA outcome. These findings provide further support that serum PSA screening increases the proportion of patients potentially curable after radical prostatectomy.

Questionnaire-based outcomes of urinary incontinence and satisfaction rates after radical prostatectomy in a national study population.

OBJECTIVES: To assess the incidence of incontinence and the associated quality of life in men younger than 65 years of age after radical prostatectomy. METHODS: The TRICARE/CHAMPUS database was searched to identify 1000 patients who underwent radical prostatectomy within 2 years before study initiation. All patients were younger than 65 years of age at the time of surgery and had at least 18 months of postoperative follow-up. An eight-part questionnaire focusing on continence after surgery was mailed to the study population. Respondents reported on voiding dysfunction, degree of incontinence, satisfaction with continence, and lifestyle impact of incontinence. RESULTS: A total of 674 eligible patients (78%) completed the survey. Any amount of pad use or changing of underwear to keep dry was reported by 31.7%, leakage once per day occurred in 16.8%, and leakage more than once per day in 9.2%. Severe urgency or urge incontinence occurred in 17.4% and was the primary cause of incontinence in one third of patients with incontinence. Only 8.9% of patients used two or more pads per day, and severe incontinence (more than four pads per day) occurred in 2.7%. Incontinence-corrective surgery was used by 4.9% of patients. Overall, 83.3% of patients reported satisfaction with their continence after surgery, and 12% considered postoperative incontinence to be a problem. CONCLUSIONS: The results of this questionnaire-based outcomes evaluation of a large national sample of prostatectomy patients younger than 65 years of age demonstrate that incontinence rates in this younger population are similar to those in the Medicare population and may be more representative of the national experience than single-center reports.

Preoperative cardiopulmonary risk assessment as predictor of early noncancer and overall mortality after radical prostatectomy.

OBJECTIVES: To evaluate the capability of the preoperative cardiopulmonary risk assessment to predict early noncancer and overall mortality after radical prostatectomy for clinically localized prostate cancer. METHODS: In 444 consecutive radical prostatectomy patients, the American Society of Anesthesiologists Physical Status classification and the presence of cardiac insufficiency (New York Heart Association classification), angina pectoris (Canadian Cardiovascular Society classification), diabetes, hypertension, history of thromboembolism, and chronic obstructive or restrictive pulmonary disease were assessed. Kaplan-Meier time-event curves and Mantel-Haenszel hazard ratios were estimated for noncancer (other deaths were censored) and overall mortality. Cox proportional hazard models were used to analyze possible combined effects of risk factors. RESULTS: During an average follow-up of 4.7 years, 36 patients died: 15 of noncancer causes, 14 of prostate cancer, 6 of other cancers, and 1 in a car accident. The comorbidity scores for American Society of Anesthesiologists Physical Status classification, New York Heart Association classification, and Canadian Cardiovascular Society classification and combinations between the latter two scores were significantly associated with early noncancer mortality in a dose-response pattern. Furthermore, patients with chronic obstructive pulmonary disease were at increased risk. The association with overall mortality was less strong. CONCLUSIONS: The preoperative cardiopulmonary risk assessment may be used as a predictor of early noncancer and overall mortality after radical prostatectomy and should be evaluated further as a source of prognostic information in surgical oncology.

Using the percentage of biopsy cores positive for cancer, pretreatment PSA, and highest biopsy Gleason sum to predict pathologic stage after radical prostatectomy: the Center for Prostate Disease Research nomograms.

OBJECTIVES: To develop probability nomograms to predict pathologic outcome at the time of radical prostatectomy (RP) on the basis of established prognostic factors and prostate biopsy quantitative histology. METHODS: Using information from the database of the Center for Prostate Disease Research (CPDR), univariate and multivariate analyses were performed on 1510 men who had undergone transrectal ultrasound and biopsy for diagnosis and had radical prostatectomy as primary therapy, with variables of age, race, clinical stage, pretreatment prostate-specific antigen (PSA), biopsy Gleason sum, and percentage of biopsy cores positive for cancer (total number of cores positive for cancer divided by the total number of cores obtained). The percentages of biopsy cores positive were grouped as less than 30%, 30% to 59%, and greater than or equal to 60%. The three most significant variables were used to develop probability nomograms for pathologic stage. RESULTS: PSA, biopsy Gleason sum, and percentage of cores positive were the three most significant independent predictors of pathologic stage. The assigned percentage of biopsy core-positive subgroups along with pretreatment PSA and highest Gleason sum were used to develop probability nomograms for pathologic stage. CONCLUSIONS: Pretreatment PSA, highest biopsy Gleason sum, and the percentage of cores positive for cancer are the most significant predictors for pathologic stage after radical prostatectomy. On the basis of these findings, CPDR probability nomograms were developed to predict pathologic outcome at the time of RP.

Limited value of bone scintigraphy and computed tomography in assessing biochemical failure after radical prostatectomy.

OBJECTIVES: To define the utility of bone scan and computed tomography (CT) in the evaluation of patients with biochemical recurrence after radical prostatectomy. METHODS: A retrospective analysis of the Center for Prostate Disease Research database was undertaken to identify patients who underwent radical prostatectomy between 1989 and 1998. Patients who developed biochemical recurrence (two prostate-specific antigen [PSA] levels greater than 0.2 ng/mL) and underwent either bone scan or CT within 3 years of this recurrence were selected for analysis. The preoperative clinical parameters, pathologic findings, serum PSA levels, follow-up data, and radiographic results were reviewed. RESULTS: One hundred thirty-two patients with biochemical recurrence and a bone scan or CT scan were identified. Of the 127 bone scans, 12 (9.4%) were positive. The patients with true-positive bone scans had an average PSA at the time of the bone scan of 61.3 +/- 71.2 ng/mL (range 1.3 to 123). Their PSA velocities, calculated from the PSA levels determined immediately before the radiographic studies, averaged 22.1 +/- 24.7 ng/mL/mo (range 0.14 to 60.0). Only 2 patients with a positive bone scan had a PSA velocity of less than 0.5 ng/mL/mo. Of the 86 CT scans, 12 (14.0%) were positive. On logistic regression analysis, PSA and PSA velocity predicted the bone scan result (P <0.001 each) and PSA velocity predicted the CT scan result (P = 0.047). CONCLUSIONS: Patients with biochemical recurrence after radical prostatectomy have a low probability of a positive bone scan (9.4%) or a positive CT scan (14.0%) within 3 years of biochemical recurrence. Most patients with a positive bone scan have a high PSA level and a high PSA velocity (greater than 0.5 ng/mL/mo).

Influence of body weight and prostate volume on intraoperative, perioperative, and postoperative outcomes after radical retropubic prostatectomy.

OBJECTIVES: To determine the influence of body weight and prostate volume on surgical outcomes after radical retropubic prostatectomy. METHODS: Between January 1994 and July 2000, 1024 men underwent radical retropubic prostatectomy by a single surgeon. Information was collected on body weight, prostate volume, operative time, estimated blood loss, allogenic transfusion rate, intraoperative complications, perioperative complications, postoperative complications, surgical margin status, and length of hospital stay. Postoperative continence and erectile function were assessed from self-administered questionnaires. RESULTS: Body weight was not significantly related to operative time (P = 0.09), estimated blood loss (P = 0.12), allogenic transfusion rate (P = 0.49), intraoperative complications (P = 0.37), perioperative complications (P = 0.84), postoperative complications (P = 0.44), positive margin rate (P = 0.07), length of hospital stay (P = 0.27), postoperative continence (P = 0.72), or postoperative erectile function (P = 0.92). The prostate volume was significantly and directly related to the estimated blood loss (P = 0.02), allogenic transfusion rate (P = 0.01), and length of hospital stay (P = 0.01). The prostate volume was significantly and inversely related to the positive surgical margin rate (P = 0.03). The prostate volume was not significantly related to the operative time (P = 0.12), intraoperative complications (P = 0.68), perioperative complications (P = 0.73), postoperative complications (P = 0.14), postoperative continence (P = 0.23), or postoperative erectile function (P = 0.90). CONCLUSIONS: No clinically relevant risks were associated with increasing body weight. Intraoperative bleeding resulting in higher transfusion rates represented the only clinically significant outcome that was adversely impacted by prostate volume. In the hands of experienced surgeons, radical retropubic prostatectomy can be performed in heavy men and in men with large prostates with excellent outcomes.

Modified Denis technique: a simple solution for maximal hemostasis in suprapubic prostatectomy.

OBJECTIVES: To describe our experience with a modified Denis technique for hemostasis in suprapubic prostatectomy. METHODS: We reviewed the charts of 78 patients who underwent suprapubic prostatectomy using a modified Denis technique between September 1996 and June 2001. After adenomectomy, we performed a bladder neck removable partition purse-string suture, and the prostatic fossa was drained. Patients were followed up for hemorrhagic complications and bladder neck strictures for 12 months. RESULTS: The mean intraoperative hemorrhage amount was 264 mL (range 160 to 510). The postoperative irrigating fluid volume was 2000 mL (range 500 to 4500), and the bladder irrigation duration was 24 hours in 70 patients (89.8%) and 48 hours in 8 patients (10.2%). Postoperative hemorrhage, measured by the prostatic fossa drain, was 0 mL in 48 patients and had a mean value of 55 mL (range 10 to 90) in 30 patients. No hemorrhagic complication was noted. None of our patients had transfusion, bladder clot formation, or late hemorrhage. One case (1.3%) of bladder neck stricture developed. CONCLUSIONS: This modified Denis technique is very effective and easy to perform and to learn. It has solved all our hemorrhagic problems in suprapubic prostatectomy.

Evaluation of complications and results in a contemporary series of 300 consecutive radical retropubic prostatectomies with the anatomic approach at a single institution.

OBJECTIVES: To evaluate the complications and results of radical retropubic prostatectomy with the anatomic approach, at our center, to allow a comparison with published studies and precise patient counseling. METHODS: We reviewed the charts and records of the follow-up visits of all patients who consecutively underwent radical retropubic prostatectomy for clinically intracapsular prostate cancer between March 1997 and February 2002. RESULTS: The pathologic stage was pT0 in 4 patients (1.3%), pT2a in 83 (27.7%), pT2b in 116 (38.7%), pT3a in 52 (17.3%), pT3b in 38 (12.6%), and pT4 in the remaining 7 (2.4%). Extracapsular disease extension was present in 97 specimens (32.3%); it was associated with positive margins in 64 patients (21.3%). Intraoperative and postoperative complications were recorded in 19 patients (6.3%). Immediate surgical repair was necessary in 3 cases (1%) and delayed in 5 (1.7%). A stricture of the vesicourethral anastomosis was observed in 2 patients (0.7%). At a median follow-up of 29 months (range 6 to 57), a total of 262 patients (88.8%) was continent; 26 patients (8.8%) had stress incontinence, and 7 were incontinent (2.3%). Of 262 patients, 128 (48.2%) achieved continence within the first day of catheter removal. CONCLUSIONS: Radical retropubic prostatectomy is associated with low complication rates; with the anatomic approach, a limited incidence of incontinence is attainable, consistent with major referral centers.

Familial prostate cancer cases before and after radical prostatectomy do not show any aggressiveness compared with sporadic cases.

OBJECTIVES: To compare the clinical and biologic features at diagnosis between sporadic and familial clinically localized prostate cancer (CaP), and to compare the prognosis of familial with that of sporadic cases after radical prostatectomy in southwestern Europe. METHODS: Eighty-five sporadic (one case of CaP) and 37 familial (two or more CaP cases in the family) patients with clinically localized CaP undergoing radical prostatectomy were compared regarding preoperative (mean age, clinical status, mean prostate-specific antigen level, and mean Gleason score at diagnosis) and postoperative (pT, pN, and pathologic Gleason score) parameters using the Student t test, Fisher's exact test, and the chi-square test. The biochemical relapse-free survival for each group was compared using the Kaplan-Meier method and the log-rank test. RESULTS: The mean follow-up was about 51.8 months (range 1 to 156) in the sporadic group and 35 months (range 1 to 96) in the familial group. No specific preoperative and postoperative clinical or biologic feature was associated with familial CaP. Biochemical relapse occurred in 40.5% (15 of 37) of cases when the proband had a positive family history of CaP versus 32.9% (28 of 85) in the sporadic cases (P = 0.42). Biochemical relapse-free survival curves did not display any difference (P = 0.46) between familial and sporadic CaP. CONCLUSIONS: In this population, the outcome after radical prostatectomy is similar in those with and without a family history. Thus, the natural history of CaP seems to follow the same path whether the triggering point is inherited or acquired for this subset of patients during this period.

Zonal location of prostate cancer: significance for disease-free survival after radical prostatectomy?

OBJECTIVES: To analyze the zonal location of prostate cancer as a possible predictive feature of progression-free survival after radical prostatectomy. METHODS: Prostate cancers were divided into three groups according to the percentage of cancer volume (70% or more, 31% to 69%, and 30% or less) located in the transition zone (TZ). In a total of 307 patients, 5-year progression-free probabilities were estimated for different clinical and pathologic tumor characteristics using the Kaplan-Meier method. With emphasis on the percentage of cancer volume located in the TZ, univariate and multivariate analyses were performed to calculate their prognostic significance in predicting progression-free probability. RESULTS: Prostate cancer with 70% or more, 31% to 69%, and 30% or less of the cancer volume in the TZ was found in 17.3%, 6.8%, and 75.9% of the patients, respectively. Patients with tumors with 70% or more of the cancer volume in the TZ had a significantly (log-rank P = 0.0402) greater rate of biochemical cure than those with 30% or less (82.1% versus 66.2%). The increasing percentage of cancer volume located in the TZ was significantly (P = 0.0258) associated with a greater progression-free probability in univariate analysis, but did not retain independent significance (P = 0.5748) in multivariate analysis. Instead, pathologic stage (P <0.0001), lymph node involvement (P = 0.0189), and Gleason score on prostatectomy specimen (P = 0.0023) were independent prognosticators. CONCLUSIONS: The location of prostate cancer in the TZ was associated with a greater overall biochemical cure rate after radical prostatectomy. However, it was not an independent prognosticator on multivariate analysis. Therefore, the knowledge about zonal location of prostate cancer offers no advantage over the well-established prognostic factors in predicting disease recurrence.

Comparison of the American Society of Anesthesiologists Physical Status classification with the Charlson score as predictors of survival after radical prostatectomy.

OBJECTIVES: To compare the American Society of Anesthesiologists Physical Status (ASA) classification with the Charlson score in the radical prostatectomy setting. The ASA classification is a widely accepted way to evaluate perioperative risk. At present, the Charlson score is probably the most frequently used comorbidity measure to predict long-term survival after radical prostatectomy. METHODS: A total of 444 consecutive patients were enrolled in this study. The ASA classification was obtained from the anesthesia chart, and the Charlson score was assigned based on conditions noted during the preoperative cardiopulmonary risk assessment or mentioned on the discharge document. Kaplan-Meier time-event curves and Mantel-Haenszel hazard ratios were estimated for comorbid (noncancer) and overall survival. RESULTS: After a mean follow-up of 5.9 years, both classifications were able to predict comorbid and overall survival in dose-response patterns. The ASA classification was superior in terms of a clearer discrimination of the survival curves (lower P values, higher hazard ratios). Both classifications identified a high-risk group (ASA 3 and Charlson score 2 or more), but only the ASA classification sufficiently defined a low-risk group (ASA 1). CONCLUSIONS: In experienced hands, the ASA classification is a promising tool to improve the classification of prognostic comorbidity in the radical prostatectomy setting and may be used as an alternative to the Charlson score.

Efficacy and cost-effectiveness of autologous blood predeposit in patients undergoing radical prostatectomy procedures.

OBJECTIVES: To assess the efficacy and cost-effectiveness of preoperative autologous blood donation (PAD) in radical prostatectomy procedures. METHODS: A retrospective 3-year review was performed of transfusion outcomes in radical prostatectomy procedures. Cost, benefits, and cost-effectiveness were established using a previously published Markov decision analysis model. RESULTS: Three hundred eighty-four (97%) of 394 patients predonated 3.5 +/- 0.6 (mean +/- SD) autologous blood units. Of these, 2.1 +/- 1.2 units (60%) were retransfused. Forty-two (11%) of 394 patients also received allogeneic blood. Autologous blood donors received only 0.2 +/- 0.6 allogeneic blood units, compared with 1.4 +/- 1.4 (p < 0.05) units transfused to patients who did not predonate. The net costs of PAD ranged from $83 to $303 per procedure. The life-expectancy benefit of PAD ranged from 0.05 to 0.07 days. The overall cost-effectiveness of PAD was estimated to be $1,813,000 per quality adjusted life-year saved. However, PAD was significantly more cost-effective for 2 unit donations ($531,000 per quality adjusted life-year saved). CONCLUSIONS: We conclude that autologous blood donation is an effective blood conservation strategy in elective radical prostatectomy. However, the cost-effectiveness of this practice compares unfavorably with that reported for other medical interventions. Alternative and more cost-effective strategies to reduce the need for allogeneic blood in this setting must be developed.

Impact of bladder neck preservation during radical prostatectomy on continence and cancer control.

OBJECTIVES: To assess the effect of preservation of the bladder neck and other factors on the rate of postoperative urinary continence and cancer control after radical prostatectomy. METHODS: Prospective analysis of clinical and pathologic findings in 206 consecutive patients undergoing radical prostatectomy with a surgical technique that emphasizes preservation of periurethral supporting tissue, urethral length, incorporation of the posterior periurethral fascia into the vesicourethral anastomosis, and preservation of the bladder neck. RESULTS: Uni- and multivariate statistical analysis demonstrated that patient age (p = 0.033) and vesical neck contracture (p = 0.047) were predictive of incomplete return of urinary control. Preservation of the vesical neck had no impact on return of continence, but was associated with a trend to a lower incidence of vesical neck contractures. A positive bladder neck margin occurred in 6.8% of surgical specimens and was associated with a higher grade, more advanced local stage, and other positive margins in all cases. The rate of local recurrence or prostate-specific antigen (PSA)-only failure was similarly independent of whether the vesical neck was preserved or resected and reconstructed. CONCLUSIONS: Age greater than 65 and occurrence of a vesical neck contracture are adverse predictors for return of urinary continence after radical prostatectomy. Preservation of the bladder neck does not have an impact on return of urinary control but may be associated with a lower risk of vesical neck contracture. Preservation of the bladder neck does not compromise cancer control as assessed by local or PSA-only failure rates.

Value of preoperative PSA in predicting pathologic stage of patients undergoing salvage prostatectomy.

OBJECTIVE: To evaluate the relationship of prostate-specific antigen (PSA) levels and pathologic stage in patients with prostate cancer treated with radiation therapy and undergoing salvage radical prostatectomy. METHOD: Retrospective analysis of preoperative PSA levels and final pathology in 24 men undergoing salvage prostatectomy following prior radiation therapy. RESULTS: Although preoperative PSA values were significantly higher in patients with positive surgical margins, preoperative PSA levels failed to predict the presence of absence of extracapsular extension, seminal vesicle involvement, or lymph node metastasis. CONCLUSION: Our results suggest that PSA is not a reliable method of accurately predicting the pathologic stage of patients who are candidates for salvage radical prostatectomy.

Maintaining quality of care and patient satisfaction with radical prostatectomy in the era of cost containment.

OBJECTIVES: To determine the effect of shortened hospital stay after radical retropubic prostatectomy on costs, adverse surgical outcomes, and patient satisfaction. METHODS: The effect of changes in preoperative counseling, perioperative care, and analgesic management on hospital length of stay; mean cost per case and cost per hospital day; and 30-day complication, hospital readmission, and mortality rates were analyzed for a consecutive sample of 374 patients undergoing radical prostatectomy between July 1989 and November 1995. Satisfaction with length of stay, analgesic regimen, and surgical outcome was assessed in a random subset of 150 patients by anonymous questionnaire. RESULTS: Length of stay (LOS) was shortened from a median 7 to 2 nights after surgery during the study (P < 0.0001), whereas the acute complication, 30-day readmission, and 30-day mortality rates remained constant. Reducing LOS resulted in a 43% decrease in mean cost per case while mean cost per day increased by 22% to 35%. Overall patient satisfaction was high, with 83.5% of patients rating LOS as "just right" and 89.2% reporting they were "satisfied" or "very satisfied" with their pain control after surgery. CONCLUSIONS: Shortened LOS after radical retropubic prostatectomy can be accomplished safely and can meet with high levels of patient satisfaction while significantly reducing hospital-related costs. The potential for further incremental reductions in cost with reductions in LOS to less than 2 nights appears to be small, and future efforts at cost reduction for this procedure should center on decreasing the intensity of care during hospitalization.

Irradiation for locally recurrent carcinoma of the prostate following radical prostatectomy.

OBJECTIVES: To evaluate the outcome of patients treated with irradiation (RT) for isolated, clinically apparent local tumor recurrence following prostatectomy for carcinoma of the prostate (CaP). METHODS: Between May 1979 and July 1992, 35 patients received external-beam RT as sole salvage therapy for post-prostatectomy locally recurrent CaP. Patient outcome was evaluated through retrospective medical record review with respect to clinical and prostate-specific antigen-based (that is, biochemical) control rates, as well as disease-free (clinical and biochemical) and overall survival estimates. Chronic RT-induced morbidity was also examined, and pre-RT disease characteristics were evaluated for their association with disease outcome. RESULTS: With median follow-up of 5.2 years (range 1.7 to 12.1) in survivors (30 patients), 19 patients (54%) had clinical (local, 1 patient [3%]; metastatic, 7 patients [20%]) or biochemical only (11 patients [31%]) relapse. The 8-year clinical relapse-free and any relapse-free (clinical or biochemical) rates were 80% and 56%, respectively, whereas the overall survival estimate was 97%. A chronic complication(s) of treatment was noted in 15 patients (43%) but spontaneously resolved in all but 6 (17%); persistent complications were mild and associated with rectal (grade 1 to 2, 14%) and lymphatic (3%) systems. The interval between prostatectomy and local tumor recurrence, the pre-RT prostate-specific antigen serum level, the pathologic stage, and tumor differentiation may be associated with disease outcome. CONCLUSIONS: External-beam RT resulted in excellent local tumor control without serious long-term morbidity in most patients. Although this study could not define an optimal management strategy (for example, symptomatic measures only, RT, or hormonal therapy), these results provided outcome measures, in relationship to pre-RT tumor-related factors, that may be valuable for clinical decision-making.

Retrograde leak point pressure for evaluating postradical prostatectomy incontinence.

OBJECTIVES: To evaluate a technique of measuring the retrograde leak point pressure (RLPP) for assessing men with postradical prostatectomy stress urinary incontinence (SUI). METHODS: We measured RLPP in adult men by retrograde infusion of the distal urethra while simultaneously recording intraurethral pressure. The reproducibility of this test, and its dependence on urethral infusion rate, bladder volume, and anterior urethral catheter position, were evaluated. RLPP and abdominal leak point pressure (ALPP) measurements were performed in postradical prostatectomy patients. RLPP was compared with ALPP and with severity of incontinence determined by pad usage. RESULTS: Repeated RLPP measurements were not significantly different and did not change with bladder volume up to half capacity or with the location of the catheter in the anterior urethra. The differences between RLPP measurements with infusion rates of 2, 4, and 8 mL/min were also not significant. Twenty-seven men were evaluated 6 to 108 months after surgery. Of these, 22 (81%) demonstrated SUI. Mean RLPP in men without SUI (79.2 +/- 14 cm H2O) was significantly higher than in men with SUI (51.9 +/- 13 cm H2O, P < 0.01). In men with SUI, ALPP and RLPP were significantly correlated, and ALPP (49.8 +/- 24 cm H2O) was not significantly different from RLPP (51.9 +/- 13 cm H2O) Pad use and RLPP were also significantly related. CONCLUSIONS: RLPP measurements are reproducible and simple to perform. The pressure at which leakage occurs is easily identifiable as the plateau pressure. RLPP correlates significantly with the lowest of multiple ALPP measurements in men with SUI. This technique represents a reliable urodynamic alternative for evaluating men with postradical prostatectomy SUI.

Urethral catheter removal prior to hospital discharge following radical prostatectomy.

OBJECTIVES: To investigate the feasibility of early catheter removal following radical prostatectomy. METHODS: Fifty-eight consecutive patients underwent radical prostatectomy, with intent of early catheter removal. Catheter removal was based on postoperative cystograms performed on postoperative day (POD) 3 or 4. Charts were retrospectively reviewed and patients were contacted by phone and specifically questioned regarding continence and bladder control. RESULTS: Fifty-one patients (87.9%) had a cystogram performed on POD 3 or 4. In 43 patients (74.1%), the catheter was successfully removed prior to hospital discharge. Eight patients experienced either early or late complications (excluding incontinence); these included 3 patients with a superficial wound infection, 2 patients with hematuria requiring reinsertion of a urethral catheter, 1 patient with a spontaneous pneumothorax, 1 patient who developed a deep vein thrombosis and lymphocele, and 1 patient with a bladder neck contracture. Urinary continence was reported as excellent to good in 86% of the patients at a mean follow-up of 17.4 months. Three patients (5%) underwent placement of an artificial urinary sphincter. CONCLUSIONS: Catheter removal prior to hospital discharge after radical prostatectomy is feasible without any increase in morbidity.
