Abstract:The primary outcome measures were the interval to recovery of continence, and the positive margin rates. The continence status was evaluated by a third party using validated questionnaires at baseline before RRP and at 4 and 7 days, and 2 weeks, 1, 3, 6 and 12 months after RRP.
RESULTSThe suspension technique resulted in significantly greater continence rates at 1, 3 and 6 months after RRP of 53% vs 20%, 73% vs 47% and 100% vs 83%. KaplanMeier curves also showed that patients in the suspension group had a sign… Show more
“…Early multi-institutional studies in Japan found the recovery of urinary function following LRP to be slower compared to that following retropubic radical prostatectomy (RRP) (2,3). The operative procedures used to improve the recovery of urinary continence following radical prostatectomy include preserving the fascia covering the levator ani muscle (4), preserving the bladder neck (4), preserving neurovascular bundles (NVBs) (5), securing a longer functional urethra (6,7), reconstructing the posterior musculofascial plate (PMPR) (8)(9)(10), suspending the vesicourethral anastomosis (11) and performing an anterior reconstruction (12).…”
Abstract. The aim of this study was to evaluate the efficacy of our modified posterior musculofascial plate reconstruction (PMPR) procedure in laparoscopic radical prostatectomy (LRP). Prior to 2010, four operative procedures were used to expedite continence recovery: preserving the fascia covering the levator ani muscle, preserving the bladder neck, securing a functional urethral length by using a lateral-view dissection technique and suspending the vesicourethral anastomosis from the puboprostatic ligaments. Since February, 2010, a running suture between Denonvilliers' fascia (DF) and the median fibrous raphe (MFR, the fibrous tissue that lies immediately underneath the urethra) has also been used. In vesicourethral anastomosis, a double-armed running suture was performed. At the beginning of the anastomosis, the first stitches (at 1 and 11 o'clock positions on the bladder neck) were placed 1-2 cm dorsocephalad to the bladder neck (first through the seromuscular layer and then through the full thickness of the bladder neck). At the 5 and 7 o'clock positions of the urethra, the stitches were placed through the urethral mucosa as well as the the reconstructed musculofascial plate. The bladder shape was evaluated by postoperative cystography and the clinical results were compared between patients undergoing LRP without PMPR (group A) and those undergoing LRP with PMPR (group B). The cystograms demonstrated that the PMPR significantly shortened the vertical length of the bladder and significantly decreased the posterior vesicourethral angle. At 1, 3 and 6 months after LRP, the number of daily used pads was significantly lower in group B compared to that in group A and the time to achieve a pad-free status was significantly shorter in group B. Our modified PMPR procedure significantly improved the recovery of urinary continence following LRP and this improvement may be due in part to changes of the bladder shape.

“…19 trials 7, 15–32 evaluated the efficacy of PR, 7 trials 12, 33–38 evaluated the efficacy of AS, 4 trials 9–11, 14 evaluated the efficacy of PR + AR, and 2 trials 39, 40 evaluated the efficacy of PR + AS. Seven of these trials were RCTs 9, 15, 31, 32, 37, 38, 40 . Six trials 11, 18, 25, 29, 32, 33 evaluated IPSS and EPIC urinary domain scores.Figure 1Selecting the flowchart for the inclusion of studies in the meta-analysis.

Radical prostatectomy (RP) is the gold standard for the treatment of localized PCa. A meta-analysis was conducted to evaluate the effect of different techniques of pelvic floor reconstruction on urinary continence. A comprehensive search was made for trials that evaluated the efficacy of pelvic floor reconstruction. Relevant databases included PubMed, Embase, Cochrane, Ovid, Web of Science databases and relevant trials from the references. Random-effects model was used to estimate risk ratios (RRs) statistics. Pooled results of patients treated with posterior reconstruction (PR) demonstrated complete urinary continence improved at 1–4, 28–42, 90, 180 and 360 days following catheter removal. Anterior suspension (AS) was associated with improvement only at 28–42 days. The anterior reconstruction (AR) + PR was associated with urinary continence at 1–4, 90 and 180 days. AS + PR was not associated with any benefit. And PR improved social urinary continence at 7–14 and 28–42 days. No benefit was associated with AS. AR + PR had better outcomes at 90 and 180 days. AS + PR was significant improved at 28–42 and 90 days. Patients who underwent RP and PR had the least urinary incontinence. No significant benefit was observed after AS. AR + PR and AS + PR had little benefit in the post-operative period.
“…Noguchi et al 26,27 introduced a suspension manoeuvre for the VUA during radical retropubic prostatectomy (RRP). These investigators used anastomotic sutures at the 1:00 and 11:00 o'clock positions to anchor the VUA to the ligated DVC, which results in suspension of the anastomosis.…”

“…The majority of these studies were prospective studies, but they were not always randomized. 6,28 All studies evaluated continence 3 months postoperatively, 6,[26][27][28] and Noguchi et al 26 performed continence evaluation as early as 1 month after RP. Thus, early postoperative continence evaluation after catheter removal was never assessed.…”

“…6,[26][27][28] In our study, we evaluated the BNS technique in both EERPE and nsEERPE and assessed the influence of the EERPE technique on early postoperative continence. Patients were selected for EERPE or nsEERPE procedures according to specific criteria and were prospectively randomized to receive bladder suspension.…”
Several techniques have been introduced to improve early postoperative continence. In this study, we evaluated the impact of bladder neck (vesicourethral anastomosis) suspension on the outcome of extraperitoneal endoscopic radical prostatectomy (EERPE). In this research, a total of 180 patients underwent EERPE. Group 1 included patients who underwent nerve-sparing EERPE (nsEERPE) (n545), and Group 2 included patients who underwent nsEERPE with bladder neck suspension (BNS, n545). Groups 3 (n545) and 4 (n545) included patients who received EERPE and EERPE with BNS, respectively. Patients were randomly assigned to receive BNS with their nsEERPE or EERPE procedure. Perioperative parameters were recorded, and continence was evaluated by determining the number and weight of absorbent pads (pad weighing test) on the second day after catheter removal and by a questionnaire 3 months postoperatively. Two days after catheter removal, 11.1% of Group 1, 11.1% of Group 2, 4.4% of Group 3 and 8.9% of Group 4 were continent. The average urine loss was 80.4, 70.1, 325.0 and 291.3 g for the each of these groups, respectively. At 3 months, 76.5% of Group 1 and 81.3% of Group 2 were continent. The continence figures for Group 3 and 4 were 48.5% and 43.8%, respectively. Similar overall rates were observed in all groups. In conclusion, although there are controversial reports in the literature, early continence was never observed to be significantly higher in the BNS groups when compared with the non-BNS groups, regardless of the EERPE technique performed.
