[Minimal prostatic adenocarcinomas in the biopsy treated with radical prostatectomy].

FUNDAMENTALS: Valuation about clinical pathologyc facts of patients having undergone a radical prostatectomy due to a minimal prostate adenocarcinoma shown at the biopsy. METHODS: Retrospective analysis of patients having undergone a radical prostatectomy due to a minimal prostate adenocarcinoma shown at the biopsy in front of the remaining radical prostatectomies. RESULTS: In 20 patients (7.6%) out of the 260 having undergone a radical prostatectomy between 1992 and 2004 the biopsy was informed as "minimal adenocarcinoma". These patients ranged 58 to 73 years with PSA levels from 5.2 to 17.1 ng/ml. Everyone except one were clinically T1c. At the definitive pathological study the Gleason was 6, 4, 3 and 2 in 3, 3, 8 and 4 patients respectively, with one having a minimal adenocarcinoma not graded and another one with a PIN ?. 3 showed only 1 focus with a tumoral volume less than 5% of the tissue (84.2% with significant tumor or multifocal). The final staging was 1 pT0 (PIN ?), 7 pT2a, 11 pT2b and 1 pT3a (62.5% bilaterals). Relating to the remaining patients under prostatectomy, patients with minimal adenocarcinoma presented significative differences in Gleason sum (p < 0.029) and staging (p = 0.02); no in PSA mean (p = 0.243). SUMMARY: Minimal adenocarcinomas of the prostate at the biopsy are significant but do present lower staging and grading in relation with the rest of patients.

The University of Massachusetts technique of radical retropubic prostatectomy.

A modified technique of radical retropubic prostatectomy is described which takes advantage of combining the antegrade dissection of prostate described by Skinner and the early control of prostatic vasculature as publicized by Walsh. Integration of both techniques of radical retropublic prostatectomy has resulted in improved exposure and minimal blood loss. The average blood loss with this technique was 500 ml in contrast to the average blood loss of 1100 ml while performing over 300 radical retropubic prostatectomies by the standard technique. The average operating times have been 150 minutes. Because of improved exposure and reduced blood loss, it is easy to teach this technique of radical prostatectomy to the surgeon in training (resident or the registrar) without any compromise to the primary goal of surgery which is to remove all tumour. No intra-operative complications were encountered during the performance of this modified technique of radical retropubic prostatectomy.

Sociodemographic factors associated with prostatectomy utilization and concordance with the physician data query for prostate cancer (United States).

OBJECTIVES: Data from the California Cancer Registry were used to model the effect of race/ethnicity, census-derived socioeconomic status (SES), age, year, and stage at diagnosis on prostatectomy utilization in men diagnosed with prostate cancer from 1990 through 1993. Treatment received was compared with the National Cancer Institute's Physician Data Query (PDQ) to evaluate concordance. METHODS: Odds ratios (OR) and 95% confidence intervals (CI) were estimated to assess the likelihood of (a) receiving a prostatectomy and (b) receiving a treatment in concordance with the PDQ. Non-concordance was defined as a prostatectomy performed on a patient who was either diagnosed with AJCC stage III or IV prostate cancer, or was older than 70 years. All other treatments were considered compliant with the PDQ. RESULTS: Regardless of the stage at diagnosis, men who were younger and lived in a neighborhood with higher income and education levels were the most likely to receive a prostatectomy as opposed to other treatments. Black men were the least likely to be treated with prostatectomy (OR = 0.6, CI = 0.5-0.6), and the differential was evident within all income levels examined. With respect to the PDQ, black men were 1.4 times more likely to receive concordant treatment than white men (OR = 1.4, CI = 1.3-1.5). CONCLUSIONS: California black men are receiving less aggressive treatment (that is more concordant with the PDQ) when diagnosed with prostate cancer.

The impact of prostatectomy and brachytherapy in patients with localized prostate cancer.

PURPOSE: to compare urinary incontinence and erectile dysfunction symptoms reflecting quality of life and the willingness to undergo treatment again in patients treated by radical retropubic prostatectomy and low dose radiation (LDR) brachytherapy. MATERIALS AND METHODS: from July 1992 to November 2001, 158 patients with clinical localized prostate cancer were treated by radical retropubic prostatectomy with or without nerve sparring or LDR brachytherapy. To all the 158 patients we mailed a self-reporting questionnaire with 5 questions to access sexual function, 4 questions for urinary continence, and 2 for the satisfaction with the treatment and willingness to undergo treatment again. Patients had no form of adjuvant radiation therapy, or neoadjuvant or adjuvant androgen suppression therapy. A total of 56 patients (43%), 34 of the prostatectomy and 22 patients of the brachytherapy group answered the questionnaire. Questionnaire results were independently analyzed by someone else not involved with patients' treatment. RESULTS: patients self-reported some degree of erectile dysfunction in 84.8% (p = 0.01) in the group treated by prostatectomy and 23.07% (p = 0.86) in the brachytherapy group. Urinary incontinence occurred in 17.6% in the group treated by prostatectomy (p = 0.01) and in 9.5% (p = 0.52) in the brachytherapy group. Urinary incontinence and impotence significantly affected treatment satisfaction. However, considering satisfaction with the treatment and willingness to undergo treatment again, 88.2% of patients would elect surgery again and 95.5% brachytherapy again.

Use of a validated quality of life questionnaire to assess sexual function following laparoscopic radical prostatectomy.

Wide variations exist in the methods for evaluating potency following radical prostatectomy. We describe our technique of laparoscopic radical prostatectomy (LRP), present our methods for assessing the return of potency following LRP, and discuss the relevant literature. Sexual function was assessed pre- and postoperatively using the Expanded Prostate Cancer Index Composite questionnaire (EPIC). Sexual function subscale scores (SFSS) were reported as a percentage of preoperative baseline sexual function. The EPIC was also used for single-question assessment of successful intercourse. We also reviewed the literature on prospective health-related quality of life results following LRP and open radical retropubic prostatectomy. Only patients reporting preoperative intercourse were analyzed. Of these, 72 and 35% undergoing bilateral and unilateral nerve sparing (NS) reported postoperative intercourse at 12 months (P=0.01). Mean SFSS at 12 months was 61 and 57% of baseline after bilateral and unilateral NS, respectively (P=0.71). Following NS procedures, 74% of patients < or =58 years of age and 41% of patients >58 years of age reported successful intercourse at 12 months (P=0.015). Mean SFSS was 64 and 52% of baseline function (P=0.249) at 12 months for patients < or =58 and >58 years of age, respectively. In patients <58 years of age who underwent bilateral NS surgery, 82% reported intercourse at 12 months. In conclusion, return of sexual function following NS LRP in our experience is comparable to reports from centers of excellence in open prostatectomy. Standardizing data collection using validated quality of life instruments can provide both surgeon and patient with a realistic forecast of relative return to normal sexual function following prostatectomy.

Treatment outcome by risk group after radical prostatectomy in Japanese men.

BACKGROUND: North American investigators have suggested the usefulness of risk-group stratification based on prostate-specific antigen (PSA), clinical stage and biopsy Gleason score for predicting the biochemical outcome of prostate cancer after radical prostatectomy. There have been no reports of the application of this stratification to early biochemical outcome after radical surgery in Japanese men. METHODS: The study population consisted of 178 men treated with radical retropubic prostatectomy and bilateral pelvic lymph node dissection at Kitasato University Hospital (n = 110) and Kurashiki Central Hospital (n = 68) between October 1992 and May 1999. Pathologic and biochemical outcomes after radical prostatectomy were analyzed based on risk-group stratification. Risk groups were further analyzed according to detailed pathologic findings at biopsy. RESULTS: The median follow-up period for the 178 patients after radical surgery was 41.5 months (range, 2.0--82.0 months; mean, 40.9 months). Fifty-eight patients experienced PSA failure at a median of 8.0 months following surgery (range, 0.0--58.0). Risk-group stratification distinctly defined groups of pathologic findings in the radical prostatectomy specimens. The proportion of patients with PSA failure for low, intermediate and high-risk groups were 9.5%, 23.9% and 56.9%, respectively (P < 0.0001). Use of the number of cores with cancer and maximum cancer length in biopsy cores failed to improve risk stratification for PSA outcome in all risk groups. CONCLUSIONS: Risk-group stratification based on preoperative variables may significantly improve a physician's ability to counsel patients about PSA outcome after radical prostatectomy. Further improvement in risk stratification may call for use of variables other than the pathologic information in biopsy cores.

Medically and economically appropriate follow-up schedule for prostate cancer patients after radical prostatectomy.

BACKGROUND: Our goal was to determine the optimal frequency and method of follow-up after radical prostatectomy to minimize medical cost without adversely affecting patients. METHODS: Two hundred and twenty-one patients who underwent a radical prostatectomy with or without adjuvant androgen deprivation from 1989 to 1999 were selected for the study. Eighty percent of the patients received postoperative androgen deprivation. Tumor recurrence was strictly defined as detectable serum prostate specific antigen (PSA) and/or clinical findings such as local tumor detection or bone metastasis. Thirty of 221 patients experienced tumor recurrence. Risk of tumor recurrence, procedures for detection of recurrence, and PSA doubling time after biochemical failure were analyzed. RESULTS: None of the 30 patients who were examined showed definitive local recurrence or metastatic sites on the imaging study at the time of initial PSA detection, and there were no observed recurrences in the absence of detectable serum PSA. In patients who showed elevated PSA within 12 months after radical prostatectomy, PSA levels rapidly increased with doubling times ranging from 1.2 to 13.7 months. Excluding those patients, the doubling time of PSA levels ranged from 2.8 to 31.5 months. CONCLUSIONS: Prostate specific antigen screening is sufficient to detect treatment failure after radical prostatectomy, irrespective of adjuvant hormone therapy. Based on the calculated doubling time, the longest advisable interval between checks of PSA levels is estimated to be four months within the first year after radical prostatectomy, and biannually or annually thereafter. Continuously elevated PSA levels or clinical symptoms indicate surveys for local recurrences and distant metastases.

Pathological findings of radical prostatectomy specimens in Japanese men diagnosed on single core positive prostate biopsy in eight with a Gleason score less than 4.

BACKGROUND: The objective of the present study was to analyze the pathological findings of radical prostatectomy specimens diagnosed on single core positive prostate biopsy in eight systematic transrectal ultrasonography (TRUS)-guided biopsies with a Gleason score </= 4. METHODS: Between January 1993 and March 2001, 975 patients underwent TRUS-guided prostate biopsy, and 32 patients were diagnosed as having prostate cancer based only on one positive core with a Gleason score </= 4. In this study, 14 of the 32 patients who underwent radical prostatectomy without any neoadjuvant therapies were enrolled, and the pathological findings of their radical prostatectomy specimens were evaluated. RESULTS: The clinical stage of the 14 patients was T1c in 10 and T2 in four. Cancer was detected in the prostate apex in seven patients, the middle in two, the base of the peripheral zone (PZ) in three, the lateral horn of the PZ in one and the transitional zone (TZ) one. Pathological stage of the 14 patients was pT2a in four, pT2b in six, pT3a in three and pT3b one. Gleason score of the radical prostatectomy specimens in 11 patients was also </= 4. Of the 10 patients diagnosed with cT1c, extraprostatic disease was found in only one radical prostatectomy specimen. All three patients whose cancer was detected from the base of the PZ showed pT3 disease. During the median follow-up period of 47.5 months, all patients were alive with no evidence of disease. CONCLUSION: The prognosis of patients who were diagnosed with one core positive prostate biopsy with a Gleason score </= 4 is generally favorable; however, advanced disease tended to be observed in patients who were diagnosed with cT2a and/or whose cancer was detected from the base of PZ.

The role of cystoscopy before radical prostatectomy.

OBJECTIVE: To determine the role of pre-operative cystoscopy in men undergoing radical prostatectomy for clinically localized adenocarcinoma of the prostate. PATIENTS AND METHODS: One hundred men undergoing radical prostatectomy for clinically localized adenocarcinoma of the prostate were evaluated for coexisting bladder pathology from a retrospective review of their charts and records. RESULTS: Four of 100 men undergoing radical prostatectomy for clinically localized prostate cancer were found to have synchronous bladder tumours. Two of these had superficial low-grade transitional cell carcinoma (TCC), one had a poorly differentiated invasive TCC and the last was found to have an inverted papilloma during radical retropubic prostatectomy. The patient with invasive disease died before the initiation of definitive therapy. The other three men are free of disease 2 years after diagnosis and treatment. CONCLUSION: Because of the low cost and minimal morbidity of pre-operative flexible cystoscopy, we recommend that this procedure be performed on the operating table before prostatectomy. In patients with gross or microscopic haematuria, a significant history of smoking, a prior history of urothelial malignancy or symptoms of bladder outlet obstruction, cystoscopy would be best performed before surgery in an out-patient setting.

The effect of prostatectomy on symptom severity and quality of life.

OBJECTIVE: To determine the effectiveness of prostatectomy in reducing symptom severity and bother and in improving disease-specific and general quality of life. PATIENTS AND METHODS: A prospective, cohort study was performed in National Health Service and private hospitals in the Northern, Wessex, Mersey, and South-West Thames Health Regions which comprised 5276 men undergoing prostatectomy recruited by 101 of the 106 (96%) surgeons (specialist and non-specialist) performing prostatectomy during a 6-month period. Patients were assessed using the American Urological Association (AUA) Symptom Index Score, the AUA symptom bother score, disease-specific and generic quality-of-life scores, the occurrence of adverse events (urinary incontinence, erectile impotence and retrograde ejaculation) and three global (general) questions on the results of their treatment. The outcome was assessed 3 months after surgery. RESULTS: Prostatectomy was effective in reducing both symptoms (initial mean score 20.1 reduced to 7.4, P < 0.001) and symptom bother (initial mean score 14.4 reduced to 4.3, P < 0.001). Not all men experienced a good reduction in symptoms; 121 (3.9%) were worse, 301 (9.6%) were the same, and 721 (23%) experienced only slight improvement. The type of operation, grade of principal operator and use of pre-operative investigations were not associated with the extent of symptomatic improvement. Changes in symptom severity were highly correlated with changes in bothersomeness++ and disease-specific quality of life but not with generic quality of life. A third of men who were continent before surgery reported some incontinence 3 months later, although only 6% found it a problem. Two-thirds of men experienced retrograde ejaculation and 31% experienced some erectile impotence following surgery. CONCLUSIONS: Prostatectomy is effective in reducing symptoms in most men. Men who experience a substantial reduction in symptoms were more likely to report a favourable outcome. The study confirmed that approximately one-third of men reported an unfavourable result 3 months after their operation.

Treatment-seeking behaviour and stated preferences for prostatectomy in Spanish men with lower urinary tract symptoms.

OBJECTIVES: To determine whether men in the community with lower urinary tract symptoms sought treatment, would choose to have a prostatectomy, and the factors that might influence their decision. SUBJECTS AND METHODS: The study was a cross-sectional population survey using interviewers in the autonomous community of Madrid and comprised 2002 men aged > or = 50 years. The main outcome measures were self-reported International Prostate Symptom Scores (IPSS), treatment-seeking behaviour and the patients' stated preference for prostatectomy. RESULTS: The response rate among eligible subjects was 68.1%; overall, 38.2% of men sought medical advice for their lower urinary tract symptoms. Whether a man sought medical advice was related to symptom severity, 'bothersomeness', interference in daily activities and his perception of the future; of these, bothersomeness and interference in activities were more likely to determine whether or not a man consulted his doctor. Most men in the sample (84.9%) reported that they would choose a prostatectomy, although this value depended on whether they had had a previous prostatectomy, were younger, and on the content of the information presented. Men were more likely to report that they would accept surgery if their doctor recommended it and less likely when presented with information on the outcomes of treatment. CONCLUSION: Many Spanish men with lower urinary tract symptoms do not seek medical advice for their symptoms, although most stated that they would accept a prostatectomy on the recommendation of their doctor. Further research should examine whether reported patient preferences correspond to actual behaviour and what is the most appropriate type of information to give to potential patients.

Effect of radical retropubic prostatectomy on erectile function, evaluated before and after surgery using colour Doppler ultrasonography and nocturnal penile tumescence monitoring.

OBJECTIVE: To assess the effect of radical retropubic prostatectomy on erectile function, by evaluating objectively patients' erectile function before and after surgery. PATIENTS AND METHODS: The study comprised 126 patients with clinically localized prostate cancer who were scheduled to undergo radical retropubic prostatectomy. After giving informed consent for the study, 123 patients underwent intracavernosal injection tests, colour Doppler ultrasonography and nocturnal penile tumescence monitoring before and after surgery. RESULTS: From the intracavernosal injection tests and nocturnal penile tumescence monitoring, 21 patients (17%) were evaluated as having normal erectile function before surgery. After radical retropubic prostatectomy, nine (43%) of these 21 potent men had preserved erectile function. In eight patients whose neurovascular bundles were preserved, five were potent after surgery. The cause of erectile function after surgery was a neurogenic disorder in seven and a related vascular disorder in five. CONCLUSION: From objective tests of erectile function on patients scheduled to undergo radical prostatectomy, 17% had normal erectile function. However, even after nerve-sparing radical retropubic prostatectomy, the proportion retaining potency was unsatisfactory. Although a neurological disorder was the main cause of erectile dysfunction after surgery, vascular disorders were also important.

Prognostic significance of the diameter of perineural invasion in radical prostatectomy specimens.

We assessed whether the quantification of cancer invasion into the perineural space influences the prognosis of patients treated with radical prostatectomy. We conducted a retrospective study of clinical and pathologic features in 640 consecutive patients with clinical stage Tla-T3bNXM0 prostate cancer who were treated with radical retropubic prostatectomy by the same surgeon between 1989 and 1995. None had received preoperative hormonal therapy or radiotherapy. Detailed pathologic analysis, including the presence and maximum diameter of perineural invasion (PNI), was performed by 2 pathologists. Treatment failure was defined as either a serum prostate-specific antigen (PSA) level > 0.4 ng/mL and rising or initiation of adjuvant therapy. The median follow-up time was 48 months (range, 1 to 111 months). Overall, PNI was detected in 477 patients (75%). The progression-free 5-year probability rate after prostatectomy for patients with PNI was 70% +/- 3% compared with 94% +/- 2% for patients without PNI (P <.001). The mere presence of PNI was not an independent predictor of progression in a Cox proportional hazards analysis when the other established prognostic factors (serum PSA level, pathologic stage, surgical margin, and tumor volume) were considered. However, the increasing diameter of the largest focus of PNI was strongly associated with other established prognostic factors and the probability of progression after radical prostatectomy. Although little adverse effect in patients with PNI < 0.25 mm was seen 5 years after surgery, those with a PNI diameter of 0.25 to 0.5 mm were significantly (P <.001) less likely to remain free of progression; only 36% of those with PNI of 0.5 to 0.75 mm (P <.001) and 14% of those with PNI > or =0.75 mm (P =.002) were free of progression. In a Cox proportional hazard analysis, the PNI diameter was an independent predictor of prognosis. These results support that the measurement of the PNI diameter, easily recorded from prostatectomy specimens, could add important information to the prognosis of prostate cancer patients. Controversy regarding the significance of PNI may result from the lack of quantitative assessment of PNI in previous studies.

Salvage radical prostatectomy: refinement of an effective procedure.

Salvage radical prostatectomy has undergone significant refinement over the past decade. This update on salvage radical prostatectomy will review improvements in patient selection, modifications in surgical technique, and compare the efficacy of salvage prostatectomy with that of salvage cryotherapy and brachytherapy. When performed by experienced surgeons, the procedure has a low rate of serious side effects and with modifications to surgical techniques; the risk for specific complications such as incontinence and bladder-neck contracture can be reduced or eliminated. The biochemical outcome after salvage prostatectomy appears superior to the biochemical outcome after salvage cryotherapy or brachytherapy. Salvage radical prostatectomy may cure approximately 50% of well-selected patients.

Perineal complications following radical perineal prostatectomy.

PURPOSE: Radical perineal prostatectomy has recently attracted renewed interest and wider acceptance as an alternative route to the retropubic approach. While presumed lower morbidity is one reason for perineal prostatectomy we evaluated our patients for complications that are specific for the perineal approach. PATIENTS AND METHODS: We have retrospectively analyzed 412 patients who underwent perineal prostatectomy from 10/1996 to 12/2000. Patients for the perineal approach were selected on the base of preoperative PSA (10 ng/ml) and biopsy Gleason score (< 7) without the need for simultaneous lymphadenectomy. A cystogram was performed routinely on day 7 p. o. and the catheter removed when patent anastomosis was confirmed. Intra-, peri- and postoperative complications were recorded and evaluated. RESULTS: Intraoperative complications encompassed 22 cases of rectal injury (5.5 %) with standard primary 2-layer closure, however 4 patients subsequently developed a stool fistula and 3 required a colostomy. Hematoma in the prostatic fossa was diagnosed in 21 patients (5.2 %) and was removed surgically due to infection or increasing size in 4 patients. In 6.5 % of the patients acute urinary retention occurred after catheter removal (91 % after 7 days), while 4.2 % showed urinary extravasation via the perineal wound. Both incidents healed uneventfully with prolonged catheterization in all except 2 cases with concomitant hematoma in whom open fistula closure with a tunica vaginalis graft was performed. The rate of perioperative transfusion was 6.4 %, transient paresthesia and weakness of the leg were observed in 3 patients. CONCLUSIONS: Radical perineal prostatectomy seems to be a procedure with a low rate of complications and surgical reinterventions. However, the spectrum of observed complications is different to that of retropubic prostatectomy and requires specific management.

Laparoscopic radical retropubic prostatectomy combined with approaches through a small open incision.

PURPOSE: The laparoscopic technique is now applied to radical prostatectomy. However, even in laparoscopic prostatectomy, we need a small open wound to remove the prostate from the abdomen. We have developed a modified technique of extraperitoneal laparoscopic radical prostatectomy, exploiting this small open wound as a route for surgical manipulations as well. Here, we described our technique and its initial outcomes. PATIENTS AND METHODS: An extraperitoneal retropubic space was developed with finger manipulations through a 3- to 5-cm long suprapubic incision. Three or four trocar ports were set up. A specially designed abdominal wall-lifter was applied to create an endoscopic working space. The surgeons worked using open or endoscopic manipulations through the suprapubic incision or the trocar ports. From October 2000 to August 2001, 11 patients with prostate cancer underwent this surgery. RESULTS: We completed surgery endoscopically without major complications except in one case in which we could not identify a bleeding source. Surgical time ranged from 229 to 469 min. Blood loss ranged from 550 to 3797 ml including urine spilled in the surgical field. Urinary continence returned in 10 cases at 1 to 8 months after surgery. One patient still needed pads at 3 months after surgery. CONCLUSION: Our technique allowed us to avoid insufflation of the abdomen with gas and intraperitoneal surgical intervention that are disadvantages of conventional laparoscopic prostatectomy, offering the same advantages as conventional laparoscopic prostatectomy.

[Quality of life following radical prostatectomy].

PURPOSE: To investigate quality of life in prostate cancer patients after radical retropubic prostatectomy. MATERIALS AND METHODS: 401 men who underwent radical prostatectomy between January 1995 and September 1999 at our clinic were asked for information concerning daily life activities, overall satisfaction, voiding ability and sexual activity in standardized questionnaire. RESULTS: The average follow-up was 36 months, 72 % (n = 289) of our patients replied. In 53 (18%) of the men who replied to our questionnaire, the nerve-sparing technique had been used. At the time our patients were questioned, 202 (70%) did not use any pads, and 211 (73%) were satisfied or very satisfied with the outcome. Of these patients 98% would undergo a radical prostatectomy again. 13% (n = 37) of our patients reported limited satisfaction, 14% (n = 41) were not satisfied with their postoperative status. However, 69% of this latter group would nevertheless decide to have a radical prostatectomy again. Of the patients who underwent the nerve-sparing technique, 68% (n = 36) reported sufficient erections for sexual intercourse, four of them under medication with sildenafil. Patients who underwent the nerve-sparing technique reported better results in daily life activities, general health status, IPSS-score and continence. While age at the time of radical prostatectomy did not influence life quality, we found substantial correlation with the postoperative tumor stage. CONCLUSIONS: Our results underline the importance of early prostate cancer detection, not only regarding a lower recurrence rate, but also because of a better postoperative quality of life.

Variations in morbidity after radical prostatectomy.

BACKGROUND: Recent studies of surgery for cancer have demonstrated variations in outcomes among hospitals and among surgeons. We sought to examine variations in morbidity after radical prostatectomy for prostate cancer. METHODS: We used the Surveillance, Epidemiology, and End Results-Medicare linked data base to evaluate health-related outcomes after radical prostatectomy. The rates of postoperative complications, late urinary complications (strictures or fistulas 31 to 365 days after the procedure), and long-term incontinence (more than 1 year after the procedure) were inferred from the Medicare claims records of 11,522 patients who underwent prostatectomy between 1992 and 1996. These rates were analyzed in relation to hospital volume and surgeon volume (the number of procedures performed at individual hospitals and by individual surgeons, respectively). RESULTS: Neither hospital volume nor surgeon volume was significantly associated with surgery-related death. Significant trends in the relation between volume and outcome were observed with respect to postoperative complications and late urinary complications. Postoperative morbidity was lower in very-high-volume hospitals than in low-volume hospitals (27 percent vs. 32 percent, P=0.03) and was also lower when the prostatectomy was performed by very-high-volume surgeons than when it was performed by low-volume surgeons (26 percent vs. 32 percent, P<0.001). The rates of late urinary complications followed a similar pattern. Results for long-term preservation of continence were less clear-cut. In a detailed analysis of the 159 surgeons who had a high or very high volume of procedures, wide surgeon-to-surgeon variations in these clinical outcomes were observed, and they were much greater than would be predicted on the basis of chance or observed variations in the case mix. CONCLUSIONS: In men undergoing prostatectomy, the rates of postoperative and late urinary complications are significantly reduced if the procedure is performed in a high-volume hospital and by a surgeon who performs a high number of such procedures.
