Project description:PurposePostoperative recovery of urinary continence has a great impact on quality of life for patients undergoing robot-assisted radical prostatectomy (RARP). A variety of surgical techniques including reconstruction of the periurethral structure have been introduced, and yet there are no effective methods that promote early urinary continence recovery after surgery. We hypothesized that the preservation of pelvic floor muscle structure could be responsible for early recovery of urinary continence after surgery.MethodsA total of 94 consecutive patients who underwent RARP at our hospital were enrolled in this study. Operative video records were reviewed and the severity of pelvic floor muscle injury was classified according to the scoring system that we devised in this study. Briefly, damage of pelvic floor muscles was classified into 4 categories; intact, fascial injury, unilateral muscle injury, and bilateral muscle injury. The volume of urinary incontinence was measured for 2 days after removal of the urethral catheter, and the incontinence ratio (amount of incontinence/total volume of urine per day) was calculated. Predictive factors for immediate incontinence after catheter removal were identified by multivariate regression analysis.ResultsThe severity of puboperineal muscle injury was significantly associated with the early incontinence ratio after catheter removal (p < 0.001). Age at surgery and severity of puboperineal muscle injury were independent predictors for early incontinence after catheter removal.ConclusionPreservation of the pelvic floor muscle, particularly the puboperineal muscle is an important factor for early continence recovery after RARP.

Project description:ObjectiveTo evaluate the safety profile and short-term functional outcome of sustainable functional urethral reconstruction (SFUR) in robotic-assisted radical prostatectomy (RARP).MethodsOne hundred and sixty-two consecutive prostate cancer patients who underwent RARP were retrospectively analyzed, in which 53 had undergone SFUR while the other 109 had undergone conventional RARP procedures. Immediate, 2-week, 1-month and 3-month continence recovery and other perioperative data were compared to evaluate short-term surgical and functional outcome.ResultsThe median age was 68 and 67 years in the experimental group and control group, respectively (p=0.206), with a median prostate-specific antigen (PSA) of 13.6 ng/mL (interquartile range [IQR], 8.46-27.32 ng/mL) in the experimental group and 13.84 ng/mL (IQR, 9.12-26.80 ng/mL) in control group (p=0.846). Immediate, 2-week, 1-month and 3-month continence recovery rates between the groups were 34.0% vs. 3.7%, 50.9% vs. 14.7%, 62.3% vs. 27.5%, and 79.2% vs. 63.3% (all p<0.05). The morphological changes made by the new reconstruction technique were maintained on magnetic resonance imaging (MRI) 3 months postoperatively. Nerve-sparing procedures and adoption of the new reconstruction technique were significantly relevant to continence recovery on logistics regression model (p<0.001).ConclusionsSFUR is a safe and easy-to-handle modification that may contribute to early continence return for RARP. Long-term follow-up and prospective studies are required to further evaluate its value in postoperative quality-of-life improvement.

Project description:Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) exhibits better postoperative urinary continence than conventional RARP (C-RARP) via the anterior approach. However, the reasons behind this are unknown. Herein, early postoperative urinary incontinence and anatomical differences of 51 propensity score-matched C-RARP and RS-RARP cases were compared. Dynamic magnetic resonance imaging (MRI) was performed before and after surgery to examine the pelvic anatomical changes under abdominal pressure. The median urine loss ratios in the early postoperative period after C-RARP and RS-RARP were 11.0% and 1.0%, respectively. Postoperative MRI revealed that the anterior bladder wall was fixed in a higher position after RS-RARP compared with its position after C-RARP. Dynamic MRI after C-RARP showed that cephalocaudal compression of the bladder while applying abdominal pressure caused the membranous urethra to expand and the urine to flow out. After RS-RARP, the rectum moved forward during abdominal pressure, and the membranous urethra was compressed by closure from behind. This is the first study using dynamic MRI to reveal the importance of high attachment of the anterior bladder wall for the urethral closure mechanism during abdominal pressure. RS-RARP, which can completely preserve this mechanism, is less likely to cause stress urinary incontinence compared with C-RARP.

Project description:BACKGROUND:The robot-assisted radical prostatectomy (RARP) has been widely applied in recent years; however, only a few studies are reported about long-term urinary continence after surgery. The present study aimed to examine the outcomes of continence rates (CRs) and determine the risk and protective factors of urinary continence in patients with prostate cancer (PCa) undergoing RARP. METHODS:This retrospective study included 650 patients treated with RARP with perioperative data and at least one year of follow-up from September 2009 to November 2017. Also, the preoperative, intraoperative, and postoperative parameters of the patients were analyzed. Continence was defined as no pad use. Early and late continence was defined as the return of urinary continence within 3?months and beyond 12?months post-surgery, respectively. CRs were examined from 1 to 48?months postoperatively. Logistic regression analysis evaluated the association between the predictive factors and urinary continence in the early and late stages. RESULTS:No significant difference was detected in the CR from 12 to 48?months postoperatively (P?=?0.766). Logistic regression analysis proved that pelvic lymph node dissection (PLND) was a significant risk factor of urinary continence at 1?month. Nerve-sparing (NS) was a significant protective factor of urinary continence at 1, 3, and 6?months. Advanced age was an independent risk factor of urinary continence at 6, 12, and 24?months. Other variables were not statistically significant predictors of urinary continence. CONCLUSIONS:The current results demonstrated that CR gradually improved with time within 1?year and stabilized 1?year after the surgery. PLND, NS, and age were significant determinants of continence in the early and late stages, respectively. These parameters could be used for preoperative identification of patients at high risk and counseling about postoperative expectations for urinary continence.

Project description:BackgroundThe aim of our study is to evaluate the prevalence and predictive factors of short- (30 d) and mid-term continence in a contemporary cohort of patients treated with robotic-assisted laparoscopic prostatectomy (RALP) without any posterior or anterior reconstruction at our referral academic center.MethodsData from patients undergoing RALP between January 2017 and March 2021 were prospectively collected. RALP was performed by three highly experienced surgeons following the principles of the Montsouris technique, with a bladder-neck-sparing intent and maximal preservation of the membranous urethra (if oncologically safe) without any anterior/posterior reconstruction. (Self-assessed urinary incontinence (UI) was defined as the need of one or more pads per die (excluding the need for a safety pad/die. Univariable and multivariable logistic regression analysis was used to assess the independent predictors of early incontinence among routinely collected patient- and tumor-related variables).ResultsA total of 925 patients were included; of these, 353 underwent RALP (38.2%) without nerve-sparing intent. The median patient age and BMI were 68 years (IQR 63-72) and 26 (IQR 24.0-28.0), respectively. Overall, 159 patients (17.2%) reported early (30 d) incontinence. In multivariable analysis adjusting for patient- and tumor-related features, a non-nerve-sparing procedure (OR: 1.57 [95% CI: 1.03-2.59], p = 0.035) was independently associated with the risk of urinary incontinence in the short-term period, while the absence of cardiovascular diseases before surgery (OR: 0.46 [95% CI: 0.320.67], p ≤ 0.01) was a protective factor for this outcome. At a median follow-up of 17 months (IQR 10-24), 94.5% of patients reported to be continent.ConclusionsIn experienced hands, most patients fully recover urinary continence after RALP at mid-term follow-up. On the contrary, the proportion of patients who reported early incontinence in our series was modest but not negligible. The implementation of surgical techniques advocating anterior and/or posterior fascial reconstruction might improve the early continence rate in candidates for RALP.

Project description:The present study seeks to present a single-blind, randomized control trial of a hypothermic anti-inflammatory device, the endorectal cooling balloon (ECB), to assess whether regional hypothermia could improve 90-day and time to pad-free continence following robot-assisted radical prostatectomy (RARP). Five high-volume surgeons at three institutions had patients randomized (1:1) to regional hypothermia with ECB versus control. Patients were blinded to device use, as it was inserted and removed intraoperatively. Knowledge of device use was restricted to the operating room personnel only; recovery room and ward nursing staff were not informed of device use and instructed to indicate such if a patient inquired. An independent and blinded data acquisition contractor assessed outcomes via components of the EPIC and IPSS. The primary outcome was categorical pad-free continence at 90-days and the secondary outcome was a Kaplan-Meier time-to pad-free continence at 90?days. 100 hypothermia and 99 control patients were included. The primary outcome of 90-day pad-free continence was 50.0% (27.8-70.0%) in the hypothermia group versus 59.2% (33.3-78.6%) in the control (p?=?0.194). The secondary outcome of Kaplan Meier analysis for time to 90-day continence was not statistically significant. At one year, there were also no statistically significant differences in continence recovery. Post-hoc analysis revealed a trend towards improvement in continence in one of three sites. Overall, the trial demonstrated no benefit to regional hypothermia either in our primary or secondary outcomes. It is suggested that surgical technique and prevention of surgical trauma may be more advantageous to improving continence recovery.

Project description:ObjectivesTo assess the relationship between the surgical procedure of robot-assisted radical prostatectomy (RARP) and urinary continence recovery by reviewing the video database.MethodsVideo and data about men diagnosed with prostate cancer and underwent RARP were extracted and reviewed. Preserved urethral length (PUL) was semi-quantitatively measured using the lateral width of a 16-Fr urethral balloon catheter while cutting the urethra on a video screen. In addition, by reviewing intraoperative RARP video database, other surgical skill outcomes were also collected. Kaplan-Meier analysis with log-rank test was used to compare the urinary continence recovery rate, stratified by the PUL. Univariate and multivariate analyses were performed using the Cox proportional hazards model, and p-values of <0.05 were considered significant.ResultsThe number of patients included in this study was 213. In univariate analysis, a PUL of ≥16 mm, a body mass index of <23.1 kg/m2 and a resected prostate volume of <44.3 g were statistically significant factors that influenced urinary continence recovery [hazard ratio (HR) 1.58, p = 0.036; HR 0.67, p = 0.021; and HR 0.58, p = 0.005, respectively]. Those factors also remained statistically significant in the multivariate analysis (HR 1.87, p = 0.022; HR 0.54, p = 0.001; and HR 0.57, p = 0.005, respectively). One year post-operatively, the recovery rate from urinary continence was 79.0% for patients with a PUL of ≥16 mm and 66.5% for patients with a PUL of <16 mm.ConclusionThese results suggest that patients with longer PUL in RARP have a significantly higher rate of post-operative urinary continence recovery.

Project description:Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). However, whether the PFME guided by a therapist (G-PFME) can contribute to the recovery of urinary continence for patients after RP is still controversial. We performed this meta-analysis to investigate the effectiveness of G-PFME on UI after RP and to explore whether the additional preoperative G-PFME is superior to postoperative G-PFME alone. Literature search was conducted on Cochrane Library, Embase, Web of Science, and PubMed, to obtain all relevant randomized controlled trials published before March 1, 2018. Outcome data were pooled and analyzed with Review Manager 5.3 to compare the continence rates of G-PFME with control and to compare additional preoperative G-PFME with postoperative G-PFME. Twenty-two articles with 2647 patients were included. The continence rates of G-PFME were all superior to control at different follow-up time points, with the odds ratio (OR) (95% confidence interval [CI]) of 2.79 (1.53-5.07), 2.80 (1.87-4.19), 2.93 (1.19-7.22), 4.11 (2.24-7.55), and 2.41 (1.33-4.36) at 1 month, 3 months, 4 months, 6 months, and 12 months after surgery, respectively. However, there was no difference between additional preoperative G-PFME and postoperative G-PFME, with the OR (95% CI) of 1.70 (0.56-5.11) and 1.35 (0.41-4.40) at 1 month and 3 months after RP, respectively. G-PFME could improve the recovery of urinary continence at both early and long-term stages. Starting the PFME preoperatively might not produce extra benefits for patients at early stage, compared with postoperative PFME.

Project description:IntroductionTo determine the clinical predictive factors affecting the recovery from postoperative urinary incontinence after robot-assisted radical prostatectomy (RARP).Materials and methodsWe consecutively analyzed 320 patients who underwent RARP between January 2012 and March 2015. The restoration of urinary continence was defined as follows: the use of no pads/no leakage of urine or the use of a safety pad. Preoperative covariates were statistically assessed by multivariate logistic regression analysis to investigate their predict factor to recovery of urinary incontinence. Therefore, in this study, we sought to identify predictors of early urinary continence status in a single-center retrospective study of consecutive patients who underwent RARP.ResultsContinence rates at 1, 3, 6, and 12 months after the catheter was removed were 44%, 71%, 83%, and 93%, respectively. Age, body mass index, and prostate volume had no significant association with urinary continence recovery. In contrast to this, longer preoperative membranous urethral length (MUL) was significantly associated with earlier postoperative continence recovery. Multivariate analysis demonstrated that longer preoperative MUL is significantly associated with continence recovery at 1 month (P = 0.0235).ConclusionApproximately 70% of patients achieved urinary continence within 3 months after RARP. Multivariate analysis showed that age, body mass index, and prostate volume had no significant association with urinary continence recovery. Preoperative MUL assessed by magnetic resonance imaging was an independent predictor of early recovery from urinary incontinence after RARP.

Project description:BackgroundIt is not clear whether the routine placement of a pelvic drain after robot-assisted radical prostatectomy is a necessity. The aim of this study was to investigate this through a meta-analysis of RCTs and non-randomized studies.MethodsA search was performed in PubMed/MEDLINE, Embase, the Cochrane Library, and the Web of Science, up to 9 March 2023, for clinical trials comparing no drain with pelvic drain placement for patients with prostate cancer after robot-assisted radical prostatectomy. Two researchers independently conducted literature screening, data extraction, and quality assessment. A random-effect model was assumed for all analyses. The Cochrane Collaboration's risk-of-bias tool was used to evaluate the methodological quality of RCTs and, for non-randomized studies, the ROBINS-I tool was used (where ROBINS-I stands for Risk Of Bias In Non-randomized Studies - of Interventions). This meta-analysis was prospectively registered in PROSPERO, the international prospective register of systematic reviews (CRD42023406429).ResultsA total of six studies with 1480 patients were included in the meta-analysis. Both the meta-analysis of RCTs and the meta-analysis of non-randomized studies showed that patients without drains had a similar estimated blood loss (mean difference 40.49 ml, 95% c.i. -59.75 to 140.74 ml, P = 0.430, and mean difference -14.20 ml, 95% c.i. -32.26 to 3.87 ml, P = 0.120 respectively), overall complication rate (OR 0.60, 95% c.i. 0.35 to 1.04, P = 0.070, and OR 0.90, 95% c.i. 0.59 to 1.39, P = 0.640 respectively), Clavien-Dindo grade I-II complication rate (OR 0.62, 95% c.i. 0.34 to 1.13, P = 0.120, and OR 0.83, 95% c.i. 0.28 to 2.51, P = 0.750 respectively), Clavien-Dindo grade III-V complication rate (OR 0.60, 95% c.i. 0.10 to 3.69, P = 0.590, and OR 0.92, 95% c.i. 0.25 to 3.39, P = 0.900 respectively), and duration of hospital stay (mean difference -0.08 days, 95% c.i. -0.45 to 0.29 days, P = 0.670, and mean difference -0.64 days, 95% c.i. -2.67 to 1.39 days, P = 0.540 respectively) compared with routinely drained patients. Meta-analysis of non-randomized studies revealed that the duration of operation for patients without drains was shorter than that for patients with drains (mean difference -34.88 min, 95% c.i. -43.58 to -26.18 min, P < 0.001), but the meta-analysis of RCTs indicated that there was no significant difference between the two groups (mean difference -7.64 min, 95% c.i. -15.61 to 0.32 min, P = 0.060).ConclusionThe intraoperative and postoperative outcomes of patients without drains were not inferior to those of patients with drains. In selected patients, pelvic drains can be omitted after robot-assisted radical prostatectomy.
