Radical prostatectomy, sparing of the seminal vesicles, and painful orgasm.

INTRODUCTION: Erectile dysfunction has been widely investigated as the major factor responsible for sexual bother in patients after radical prostatectomy (RP); painful orgasm (PO) is one element of this bother, but little is known about its prevalence and its effects on sexual health. AIM: This study aims to investigate the prevalence of PO and to identify potential risk factors. MAIN OUTCOME MEASURES: A total of 1,411 consecutive patients underwent open (radical retropubic prostatectomy) or robot-assisted laparoscopic RP between 2002 and 2006. The patients were asked to complete a study-specific questionnaire. METHODS: Of a total of 145 questions, 5 dealt with the orgasmic characteristics. The questionnaire was also administered to a comparison group of 442 persons, matched for age and area of residency. RESULTS: The response rate was 91% (1,288 patients). A total of 143 (11%) patients reported PO. Among the 834 men being able to have an orgasm, the prevalence was 18% vs. 6% in the comparison group (relative risk [RR] 2.8, 95% confidence interval [CI] 1.7-4.5). When analyzed as independent variables, bilateral seminal vesicle (SV)-sparing approach (RR 2.33, 95% CI 1.0-5.3, P = 0.045) and age <60 years were significantly related to the presence of PO (95% CI 0.5-0.9, P = 0.019). After adjustment for age, bilateral SV-sparing still remained a significant predictor for occurrence of PO. CONCLUSIONS: We found that PO occurs significantly more often in patients undergoing bilateral SV-sparing RP when compared with age-matched comparison population.

Pad use and patient reported bother from urinary leakage after radical prostatectomy.

PURPOSE: To better understand clinically significant definitions of urinary incontinence we investigated the relationship between urinary leakage and patient reported bother from urinary leakage. MATERIALS AND METHODS: A consecutive series of 1,411 men who underwent radical prostatectomy at Karolinska University Hospital, Stockholm, Sweden, from 2002 to 2006 were invited to complete a study specific questionnaire with questions on pad status, urinary leakage and bother from urinary leakage. RESULTS: Questionnaires were received from 1,179 men with a followup of greater than 1 year (median 2.2). Results showed that even a small amount of urinary leakage resulted in a high risk of urinary bother. Of 775 survivors 46 (6%) reporting 0 pads indicated moderate or much bother compared to 38 of 123 (31%) who reported using a security pad. When comparing the 2 groups, the risk of bother from urinary leakage was more than 5 times higher in the safety pad vs the 0 pad group (RR 5.2, 95% CI 3.5-7.7). As the number of pads increased, we noted a higher bother risk. Cross-tabulation of pad use and urinary leakage revealed wide variation in pad requirements despite the same answer to urinary leakage questions. CONCLUSIONS: If the definition of continence is based on pad use, for example safety pads, a certain number of men who report moderate or much bother from urinary leakage will be defined as continent. Our results also show that for each stated rate of urinary leakage men prove to have a major variation in the pad requirement.

Orgasm-associated urinary incontinence and sexual life after radical prostatectomy.

INTRODUCTION: Involuntary release of urine during sexual climax, orgasm-associated urinary incontinence, occurs frequently after radical prostatectomy. We know little about its prevalence and its effect on sexual satisfaction. AIM: To determine the prevalence of orgasm-associated incontinence after radical prostatectomy and its effect on sexual satisfaction. METHODS: Consecutive series, follow-up at one point in calendar time of men having undergone radical prostatectomy (open surgery or robot-assisted laparoscopic surgery) at Karolinska University Hospital, Stockholm, Sweden, 2002-2006. Of the 1,411 eligible men, 1,288 (91%) men completed a study-specific questionnaire. MAIN OUTCOME MEASURE: Prevalence rate of orgasm-associated incontinence. RESULTS: Of the 1,288 men providing information, 691 were sexually active. Altogether, 268 men reported orgasm-associated urinary incontinence, of whom 230 (86%) were otherwise continent. When comparing them with the 422 not reporting the symptom but being sexually active, we found a prevalence ratio (with 95% confidence interval) of 1.5 (1.2-1.8) for not being able to satisfy the partner, 2.1 (1.1-3.5) for avoiding sexual activity because of fear of failing, 1.5 (1.1-2.1) for low orgasmic satisfaction, and 1.4 (1.2-1.7) for having sexual intercourse infrequently. Prevalence ratios increase in prostate-cancer survivors with a higher frequency of orgasm-associated urinary incontinence. CONCLUSION: We found orgasm-associated urinary incontinence to occur among a fifth of prostate cancer survivors having undergone radical prostatectomy, most of whom are continent when not engaged in sexual activity. The symptom was associated with several aspects of sexual life.

Age at surgery, educational level and long-term urinary incontinence after radical prostatectomy.

OBJECTIVE: To identify predictors for long-term urinary leakage after radical prostatectomy. PATIENTS AND METHODS: A consecutive series of 1411 patients who underwent radical prostatectomy (open surgery or robot-assisted laparoscopic surgery) at Karolinska University Hospital between 2002 and 2006 were invited to complete a study-specific questionnaire. Urinary leakage was defined as use of two or more pads per day. RESULTS: Questionnaires were received from 1288 (91%) patients with a median follow-up of 2.2 years. Age at surgery predicts in an exponential manner long-term urinary incontinence at follow-up with an estimated relative increase of 6% per year. Among the oldest patients, 19% had urinary incontinence compared with 6% in the youngest age group, translating to a prevalence ratio of 2.4 (95% confidence interval [CI], 1.5-8.1). Low educational level, as compared with high, yielded an increased age-adjusted prevalence ratio of 2.5 (95% CI, 1.7-3.9). Patients who had undergone salvage radiation therapy had an increased prevalence of urinary incontinence (2.5; 95% CI, 1.6-3.8), as did those with respiratory disease (2.4; 95% CI, 1.3-4.4). Body mass index, prostate weight, presence of diabetes or previous transurethral resection did not appear to influence the prevalence of urinary incontinence. CONCLUSIONS: In this series, a patient's age at radical prostatectomy influenced, in an exponential manner, his risk of long-term urinary incontinence. Other predictors are low educational level, salvage radiation therapy and respiratory disease. Intervention studies are needed to understand if these data are relevant to the prevalence of urinary leakage if a radical prostatectomy is postponed in an active monitoring programme.

Surgery-related complications in 1253 robot-assisted and 485 open retropubic radical prostatectomies at the Karolinska University Hospital, Sweden.

OBJECTIVES: To quantify complications to surgery in patients treated with robot-assisted radical prostatectomy (RARP) and open retropubic radical prostatectomy (RRP) at our institution. Radical prostatectomy is associated with specific complications that can affect outcome results in patients. METHODS: Between January 2002 and August 2007, a series of 1738 consecutive patients underwent RARP (n = 1253) or RRP (n = 485) for clinically localized prostate cancer. Surgery-related complications were assessed using a prospective hospital-based complication registry. The baseline characteristics of all patients were documented preoperatively. RESULTS: Overall, 170 patients required blood transfusions (9.7%), 112 patients (23%) in the RRP group compared with 58 patients (4.8%) in the RARP group. Infectious complications occurred in 44 RRP patients (9%) compared with 18 (1%) in the RARP group. Bladder neck contracture was treated in 22 (4.5%) patients who had undergone RRP compared with 3 (0.2%) in the RARP group. Clavien grade IIIb-V complications were more common in RRP patients (n = 63; 12.9%) than in RARP patients (n = 46; 3.7%). CONCLUSIONS: The introduction of RARP at our institution has resulted in decreased number of patients with Clavien grade IIIb-V complications, such as bladder neck contractures, a decrease in the number of patients who require blood transfusions, and decreased numbers of patients with postoperative wound infections.

Erectile function after robotic nerve sparing and semi-sparing of the neurovascular bundles.

We set out to present potency results after bilateral, unilateral, and semi-sparing of the neurovascular bundles after robotic prostatectomy. Two hundred and twenty-five consecutive robotic-assisted laparoscopic radical prostatectomies were performed by one surgeon (NPW) from the start of our robotic program in January 2002 until December 2005. Patient demographics, operative, and postoperative data were prospectively entered into a database. We have functional data for 183, 150, and 109 patients followed for 3, 6, and 12 months, respectively. Of 49 preoperatively potent patients 36 (73%, 95% CI 59-85%) had erections sufficient for intercourse at 12 month follow-up. If bilateral nerve sparing was performed, 13 (87%, 95% CI 59-85%) of the patients showed a return of potency sufficient for intercourse. In preoperatively potent patients who did not undergo a traditional nerve sparing due to a high-risk disease, semi-sparing of the neurovascular bundles showed a return of potency in 10 (53%, 95% CI 29-76%). After one-year follow-up, 66 of 71 (93%, 95% CI 84-98%) had no need for protective pads and two (3%) used more than one pad a day. In the first 100 patients there were 24 (24%) positive surgical margins and for the last 125 patients there were 18 (14%). Based on these data, we hypothesize that certain subgroups, e.g., men wanting to preserve their sexual potency but having a tumor that hinders a traditional nerve-sparing approach, may be particularly helped by robot-assisted laparoscopic surgery as compared with other techniques.

Karolinska prostatectomy: a robot-assisted laparoscopic radical prostatectomy technique.

OBJECTIVE: The last decade has witnessed an increasing trend towards minimally invasive management of prostate cancer, including laparoscopic and, more recently, robot-assisted laparoscopic prostatectomy. Several different laparoscopic approaches have been continuously developed during the last 5 years and it is still unclear which technique yields the best outcome. We present our current technique of robot-assisted laparoscopic radical prostatectomy. MATERIAL AND METHODS: The technique described has evolved during the course of >400 robotic prostatectomies performed by the robotic team since the robot-assisted laparoscopic radical prostatectomy program was introduced at Karolinska University Hospital in January 2002. SURGICAL PROCEDURE: Our procedure comprises several modifications of previously reported ones, and we utilize fewer robotic instruments to reduce costs. An extended posterior dissection is performed to aid in the bladder neck-sparing dissection. In nerve-sparing procedures the vesicles are divided to avoid damage to the erectile nerves. In order to preserve the apical anatomy the dorsal venous complex is incised sharply and is first over-sewn after the apical dissection is completed. CONCLUSIONS: Our technique enables a more fluent dissection than previously described robotic techniques. Minimizing changes of instruments and the camera not only cuts costs but also reduces inefficient operating maneuvers, such as switching between 30 degrees and 0 degrees lenses during the procedure. We present a technique which in our hands has achieved excellent functional and oncological results.
