Restoration of posterior aspect of rhabdosphincter shortens continence time after radical retropubic prostatectomy

PURPOSE: Prolonged postoperative incontinence is a major drawback of RRP. Age, scars in the rhabdosphincter, nonnerve sparing surgery and postoperative sphincter insufficiency can cause temporary or definitive urinary incontinence. We believe that sphincter deficiency is the main cause of early incontinence. Urinary leakage results from the shortening of anatomical and functional sphincter length due to caudal retraction of the urethral sphincteric complex and disruption of the median posterior fibrous raphe. We describe a modification of the Walsh RRP that overcomes caudal retraction, reconstructs the posterior fibrous raphe and decreases time to continence. The primary study end point was early continence rate assessment. Long-term continence (1 year) and erectile function assessment were secondary end points. MATERIALS AND METHODS: To avoid caudal retraction of the urethrosphincteric complex, before completing the vesicourethral anastomosis the posterior semicircumference of the sphincter is joined to the residuum of Denonvilliers' fascia and fixed to the posterior bladder wall 1 to 2 cm cranial and dorsal to the new bladder neck. Vesicourethral anastomosis is subsequently performed with care taken not to involve the neurovascular bundles. A total of 161 patients with clinically confined disease underwent modified RRP (group 1). They were compared with a historical series of 50 patients who underwent standard RRP (group 2). Early continence was defined as no pad use but patients using 1 diaper were also considered continent. Continence, assessed prospectively as the number of pads daily, was evaluated 3, 30 and 90 days, and 1 year after catheter removal. The continence state was assessed by a multivariate logistic model. Erectile function was evaluated using the International Index of Erectile Function questionnaire preoperatively and after 18 months in patients younger than 65 years who underwent nerve sparing surgery. RESULTS: In group 1, 116 (72%), 127 (78.8%) and 139 patients (86.3%) were continent 3, 30 and 90 days after catheter removal compared with 7 (14%), 15 (30%) and 23 (46%), respectively, in group 2. One-year continence rates were 96% and 90%, respectively. Erectile function was similar in groups 1 and 2 (46% and 42%, respectively). Multivariate analysis showed that continence was significantly influenced by operation type, stage and patient age. CONCLUSIONS: Careful reconstruction of the posterior aspect of the rhabdosphincter markedly shortens time to continence.     

The impact of open radical retropubic prostatectomy on continence and lower urinary tract symptoms: a prospective assessment using validated self-administered outcome instruments

PURPOSE: We determined the impact of radical retropubic prostatectomy on continence and lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: Between October 2000 and August 2002, 500 men with clinically localized prostate cancer underwent radical retropubic prostatectomy by a single surgeon, and completed the UCLA Prostate Cancer Index and American Urological Association (AUA) symptom index at baseline, 3, 6, 12 and 24 months after radical prostatectomy. Univariate analysis was performed to identify factors predisposing the early return of continence. RESULTS: A total of 100%, 98.3%, 97.1%, 94.2% and 98.6% of patients filled out the UCLA Prostate Cancer Index and AUA symptom index at baseline, and 3, 6, 12 and 24 months, respectively. Based on protective pad requirement or frequency of incontinence 100%, 90.9%, 87.2%, 92.1% and 98.5% vs 98.8%, 80.6%, 91.2%, 95.2% and 98.5% of men were continent at baseline, 3, 6, 12 and 24 months after surgery, respectively. Age, severity of lower urinary tract symptoms, Gleason score, nerve sparing status, blood loss or presence of benign prostatic tissue in the apical soft tissue margin did not predict early return of continence. All of the individual urinary symptoms captured by the AUA symptom score showed significant improvement after radical retropubic prostatectomy. Radical prostatectomy was associated with a mean 5.4 unit decrease in AUA symptom score (40% decrease) in men with baseline moderate/severe LUTS (AUA symptom score 8 or greater). CONCLUSIONS: The majority of men regain continence after radical retropubic prostatectomy and maximal continence is achieved by 24 months. No factors were identified that predicted early return of continence in our cohort of men undergoing radical prostatectomy. Radical prostatectomy has a clinically significant impact on improving LUTS.     

Open versus laparoscopic radical prostatectomy: a prospective comparison of postoperative urinary incontinence rates

PURPOSE: We compared the 12-month postoperative urinary incontinence rates of open radical retropubic and laparoscopic radical prostatectomy. MATERIALS AND METHODS: This prospective study included all men with clinically localized prostate cancer scheduled for radical prostatectomy (open retropubic or laparoscopic) at the University of Alberta between October 1999 and July 2002. Preoperative evaluation included a 24-hour pad test, fluid volume voiding diary and International Prostate Symptom Score questionnaire. Postoperative evaluation included a 24-hour pad test at 3 and 12 months, as well as a voiding diary and International Prostate Symptom Score questionnaire at 3, 6, 9 and 12 months. RESULTS: A total of 239 patients met the eligibility criteria and consented to participate (172 open radical retropubic prostatectomy, 67 laparoscopic radical prostatectomy). Of the patients 87% (148) treated with open radical retropubic prostatectomy and 88% (57) of those treated with laparoscopic radical prostatectomy completed 12-month followup (p = 0.50). According to 24-hour pad testing 13% of those treated with open radical retropubic prostatectomy and 17% of those treated with laparoscopic radical prostatectomy remained incontinent at 1 year (p = 0.26). There was no difference in 24-hour pad weight, urinary symptom score and urinary quality of life at 1 year between the open and laparoscopic groups overall, or when stratified according to 12-month continence status. The majority of subjects in both groups described mild symptoms and a general satisfaction with urinary quality of life. CONCLUSIONS: Based on objective and subjective measures, there were no differences in urinary functional outcomes 1 year after open radical retropubic prostatectomy or laparoscopic radical prostatectomy. Urinary incontinence was found to affect a similar proportion of patients who underwent open (13%) and laparoscopic (17%) radical prostatectomy 12 months postoperatively.     

腹腔镜前列腺癌根治术中保留神经血管束的疗效观察（附17例报告）

目的评价腹腔镜下前列腺癌根治术(LRP)中保留神经血管束(NVB)的临床意义。方法2005年8月—2008年3月,对17例局限性前列腺癌患者行LRP,术前临床分期T1b3例,T1c8例,T2b2例,T2c3例,T3a1例。术中采用保护尿道膜部括约肌和双侧前列腺旁神经血管束,重建膀胱颈部充分外翻后,间断、无张力行膀胱颈尿道吻合。结果17例手术均获成功,无一例中转开放。手术平均时间290min(190～370min),出血量平均360ml(200～640ml)。其中2例术中因处理阴茎背血管复合体(DVC)不当出现较大出血,分别为600ml和640ml,均未输血。术后随访6～37个月,全部患者排尿通畅,无肿瘤复发。14例术后6个月内恢复尿控能力,2例在术后9个月内恢复,1例术后12个月后尚存在轻度尿失禁。14例患者在术后12月内可以充分或部分勃起,3例不能勃起。结论LRP中保留双侧NVB,保护尿道膜部括约肌,能有效减少根治术后患者尿失禁及勃起障碍的发生。     

Impact of unilateral sural nerve graft on recovery of potency and continence following radical prostatectomy: 3-year longitudinal study

PURPOSE: We conducted a 3-year longitudinal study assessing the impact of unilateral sural nerve graft on recovery of potency and continence following radical prostatectomy. MATERIALS AND METHODS: A total of 113 patients undergoing radical retropubic prostatectomy were classified into 3 groups according to the degree of nerve sparing, that is unilateral nerve preservation with contralateral sural nerve graft interposition, bilateral nerve sparing and unilateral nerve sparing. Urinary continence and potency were estimated by the UCLA Prostate Cancer Index questionnaire. RESULTS: Patients in the nerve sparing plus sural nerve graft group were younger than those in the bilateral nerve sparing or unilateral nerve sparing groups. At baseline the unilateral nerve sparing plus sural nerve graft group and the bilateral nerve sparing group reported better sexual function than the unilateral nerve sparing group (62.1 and 61.5 vs 49.9, p<0.05). The bilateral nerve sparing group showed more rapid recovery than the unilateral nerve sparing plus sural nerve graft group after radical retropubic prostatectomy (p<0.01). After 24 months there were no significant differences observed between the bilateral nerve sparing and the unilateral nerve sparing plus sural nerve graft group (28.7 vs 32.9). The bilateral nerve sparing group reported a better sexual function score than the unilateral nerve sparing group throughout the postoperative period (p<0.05). The bilateral nerve sparing group maintained significantly better urinary function at 1 month after radical retropubic prostatectomy than the unilateral nerve sparing plus sural nerve graft group (p <0.05). After 3 months these groups were almost continent. The unilateral nerve sparing group reported lower urinary function scores during the first year compared to the other groups. CONCLUSIONS: The nerve graft procedure may contribute to the recovery of urinary function as well as sexual function after radical retropubic prostatectomy. This finding needs to be validated in a randomized trial.     

Posterior musculofascial plate reconstruction promotes early restoration of continence and prevents severe incontinence in patients undergoing laparoscopic radical prostatectomy

The objective of the present study was to assess the efficacy of posterior reconstruction of Denonvilliers' musculofascial plate for restoring urinary continence after laparoscopic radical prostatectomy. A total of 48 consecutive patients who underwent laparoscopic radical prostatectomy were retrospectively reviewed. Of them, 23 underwent laparoscopic radical prostatectomy without posterior reconstruction of Denonvilliers' musculofascial plate (group 1) and 25 underwent laparoscopic radical prostatectomy with posterior reconstruction of Denonvilliers' musculofascial plate (group 2). Patients' demographics were analyzed and continence rates between the two groups at 1, 3, 6 and 12 months after surgery were compared. Patients in group 2 had significantly larger prostates than in group 1. There were no significant differences between the two groups in terms of the other patient characteristics. The urinary continence rates were significantly higher in group 2 than in group 1 at 1, 3 and 12 months after surgery, and the rates of severe incontinence were significantly lower in group 2 at all time‐points considered. These findings suggest that posterior reconstruction of Denonvilliers' musculofascial plate helps in restoring early continence and decreasing severe incontinence in patients undergoing laparoscopic radical prostatectomy.     

Urinary continence after radical retropubic prostatectomy: relationship with membranous urethral length on preoperative endorectal magnetic resonance imaging

PURPOSE: We determined whether membranous urethral length on preoperative magnetic resonance imaging (MRI) is predictive of urinary continence after radical retropubic prostatectomy. MATERIALS AND METHODS: Membranous urethral length was measured on preoperative endorectal MRI in 211 consecutive patients with newly diagnosed prostate cancer before radical retropubic prostatectomy performed by a single surgeon. Neurovascular bundle resection was done in 60 cases. After surgery the time to stable postoperative continence was recorded in 180 cases and the level of stable continence was graded on a 5-point scale of 1-complete continence to 5-complete incontinence. RESULTS: After controlling for age and surgical technique multivariate analysis showed that membranous urethral length was related to time to stable postoperative continence (p = 0.02), such that a longer membranous urethra was associated with a shorter time to stable continence. For example, 1 year after surgery 120 of the 134 patients (89%) with a preoperative membranous urethral length of greater than 12 mm. were completely continent compared with 35 of the 46 (77%) with a preoperative length of 12 mm. or less. CONCLUSIONS: On endorectal MRI before radical prostatectomy a longer membranous urethra is associated with significantly more rapid return of urinary continence after surgery.
