A systematic review and meta-analysis. World J Surg Oncol 2024; 22:66. [PMID: 38395861 PMCID: PMC10885481 DOI: 10.1186/s12957-024-03340-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
CONTEXT In men with prostate cancer, urinary incontinence is one of the most common long-term side effects of radical prostatectomy (RP). The recovery of urinary continence in patients is positively influenced by preserving the integrity of the neurovascular bundles (NVBs). However, it is still unclear if bilateral nerve sparing (BNS) is superior to unilateral nerve sparing (UNS) in terms of post-RP urinary continence. The aim of this study is to systematically compare the differences in post-RP urinary continence outcomes between BNS and UNS. METHODS The electronic databases of PubMed and Web of Science were comprehensively searched. The search period was up to May 31, 2023. English language articles comparing urinary continence outcomes of patients undergoing BNS and UNS radical prostatectomy were included. Meta-analyses were performed to calculate pooled relative risk (RR) estimates with 95% confidence intervals for urinary continence in BNS and UNS groups at selected follow-up intervals using a random-effects model. Sensitivity analyses were performed in prospective studies and robotic-assisted RP studies. RESULTS A meta-analysis was conducted using data from 26,961 participants in fifty-seven studies. A meta-analysis demonstrated that BNS improved the urinary continence rate compared to UNS at all selected follow-up points. RRs were 1.36 (1.14-1.63; p = 0.0007) at ≤ 1.5 months (mo), 1.28 (1.08-1.51; p = 0.005) at 3-4 mo, 1.12 (1.03-1.22; p = 0.01) at 6 mo, 1.08 (1.05-1.12; p < 0.00001) at 12 mo, and 1.07 (1.00-1.13; p = 0.03) at ≥ 24 mo, respectively. With the extension of the follow-up time, RRs decreased from 1.36 to 1.07, showing a gradual downward trend. Pooled estimates were largely heterogeneous. Similar findings were obtained through sensitivity analyses of prospective studies and robotic-assisted RP studies. CONCLUSION The findings of this meta-analysis demonstrate that BNS yields superior outcomes in terms of urinary continence compared to UNS, with these advantages being sustained for a minimum duration of 24 months. It may be due to the real effect of saving the nerves involved. Future high-quality studies are needed to confirm these findings.

Abstract
OBJECTIVE To determine if hypogonadism leads to delayed urinary function recovery post-radical prostatectomy (RP) by studying the effect of preoperative factors including age, membranous urethral length, radiation therapy, and Body Mass Index on urinary continence in patients with or without hypogonadism. MATERIALS AND METHODS We identified 1209 patients treated by RP with both pretreatment T and post-treatment urinary outcome. We assessed whether there was an association between low preoperative T level (prenoon T ≤ 300 ng/dL) and continence (using ≤1 pad/d) at 6 and 12months post-RP. Patient-reported continence was used when available, otherwise, surgeon-assessed continence was used. Logistic regression models were used, adjusted for age at RP and nerve-sparing status. RESULTS Median age at RP was 61 (Intraquatile Range (IQR) 56, 66), 92% of patients had at least one nerve spared and 99% were continent at baseline. Continence in patients with low T was nonsignificantly lower at 6months (odds ratio 0.69, 95% confidence interval 0.44, 1.06; P = .10) and nonsignificantly higher at 12months (odds ratio 1.07, 95% confidence interval 0.71, 1.58; P = .8). Sensitivity analyses excluding patients with preoperative metastasis or treated with androgen deprivation therapy (ADT) and including testosterone as a continuous predictor were consistent with the primary analysis; similarly finding no evidence of an association. CONCLUSION Although we cannot rule out an effect on early continence, overall the evidence does not suggest that low serum testosterone adversely impacts urinary function recovery after RP. This finding can be used to counsel patients enrolled in neoadjuvant ADT trials or those patients undergoing RP who have had prior ADT, such as in the setting of oligometastatic disease.

Eur Urol Focus 2022; 8:1176-1185. [PMID: 34246618 DOI: 10.1016/j.euf.2021.06.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/08/2021] [Accepted: 06/23/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND The use of surgical clips for athermal dissection of the lateral prostatic pedicles and ligation during pelvic lymph node dissection (PLND) while performing robotic-assisted radical prostatectomy (RARP) has been the gold standard. Clips are used to prevent thermal injury of the unmyelinated nerve fibers and lymphceles, respectively. OBJECTIVE To compare oncological and functional outcomes of a new technique of clipless, lateral pedicle control and PLND with RARP with bipolar energy (RARP-bi) versus the standard RARP technique with clips (RARP-c). DESIGN, SETTING, AND PARTICIPANTS A retrospective study was conducted among 338 men who underwent RARP between July 2018 and March 2020. SURGICAL PROCEDURE RARP-c versus RARP-bi. MEASUREMENTS We prospectively collected data and retrospectively compared demographic, clinicopathological, and functional outcome data. Urinary as well as sexual function was assessed using the Expanded Prostate Cancer Index for Clinical Practice, and complications were assessed using Clavien-Dindo grading. Multivariable regression modeling was used to examine whether the technical approach of RARP-bi versus RARP-c was associated with positive surgical margins (PSMs) or sexual and urinary function scores. RESULTS AND LIMITATIONS A total of 144 (43%) and 194 (57%) men underwent RARP-bi and RARP-c, respectively. Overall, there were no differences in functional and oncological outcomes between the two approaches. On multivariable regression analysis, the RARP-bi technique was not associated with significant differences in PSMs (odds ratio [OR] = 1.04, 95% confidence interval [CI] 0.6-1.8; p = 0.9), sexual function (OR = 0.4, 95% CI 0.1-1.5; p = 0.8), or urinary function (OR = 0.5, 95% CI 0.2-1.4; p = 0.2). The overall 30-d complication rates (12% vs 16%, p = 0.5) and bladder neck contracture rates (2.1% vs 3.6%, p = 0.5) were similar between the two groups. There was no difference in lymphocele complications (1.4% vs 0.52%, p = 0.58). All complications were of Clavien-Dindo grade I-II. CONCLUSIONS Despite the concerns for an increased risk of nerve injury secondary to the use of bipolar energy for prostatic pedicle dissection, we demonstrate that this technique is oncologically and functionally similar to the standard approach with surgical clips. There was no difference in complications or lymphocele formation for techniques with versus without clips. PATIENT SUMMARY We describe a modified technique for prostatic pedicle dissection during robotic-assisted radical prostatectomy, which utilizes bipolar energy and is associated with shorter operative time, without compromising functional or oncological outcomes.

Retzius-sparing Robot-assisted Radical Prostatectomy Leads to Durable Improvement in Urinary Function and Quality of Life Versus Standard Robot-assisted Radical Prostatectomy Without Compromise on Oncologic Efficacy: Single-surgeon Series and Step-by-step Guide. Eur Urol 2020; 79:839-857. [PMID: 32536488 DOI: 10.1016/j.eururo.2020.05.010] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Accepted: 05/12/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) has been shown to improve continence. However, questions remain regarding feasibility and generalizability of technique and outcomes. OBJECTIVE To compare the outcomes of 140 consecutive standard robot-assisted radical prostatectomy (S-RARP) versus RS-RARP. DESIGN, SETTING, AND PARTICIPANTS A total of 70 S-RARPs were performed followed by 70 RS-RARPs. Demographic, pathologic, and functional outcomes were compared preoperatively and through 12 mo. Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) was used to compare functional outcomes. Logistic and linear regression analyses were utilized to analyze variables associated with EPIC-CP urinary incontinence and overall quality of life (QOL) scores, and oncologic outcomes. Cox regression analysis was used to analyze incontinence at 12 mo. SURGICAL PROCEDURE RS-RARP versus S-RARP. MEASUREMENTS Patient and tumor characteristics (age, body mass index, prostate-specific antigen, Charlson Comorbidity Index, Gleason group, clinical stage, and Prostate Imaging Reporting and Data System score), perioperative outcomes (console time, estimated blood loss, postoperative complications, and length of stay), oncologic outcomes (positive surgical margin [PSM], and biochemical recurrence), overall and 12-mo continence rates (zero pads and zero to one safety pad), time to continence, potency (erection sufficient for sexual activity), EPIC-CP urinary incontinence, sexual function, and overall QOL scores. RESULTS AND LIMITATIONS Median follow-up for S-RARP versus RS-RARP was 46.3 versus 12.3 mo. RS-RARP versus S-RARP had improved overall continence rates at total follow-up (95.7% vs 85.7%, p = 0.042) and 12-mo follow-up (97.6% vs 81.4%, p = 0.002), and faster return to continence (zero to one safety pad, 44 vs 131 d, p < 0.001). RS-RARP EPIC-CP urinary incontinence and overall QOL scores remained significantly better at 12 mo. There were no differences in overall PSM rates, although RS-RARP had lower rates of nonfocal PSMs. There were no differences in sexual function. In multivariate analysis, RS-RARP was significantly associated with improved 12-mo EPIC-CP urinary incontinence and improved QOL scores, but was not associated with PSM or biochemical recurrence. Limitations include retrospective study design and unequal follow-up; however, significantly better RS-RARP continence at 12 mo is striking despite fewer patients attaining 12-mo follow-up. CONCLUSIONS RS-RARP significantly improves early and long-term continence without compromising oncologic outcomes and leads to overall improved QOL. PATIENT SUMMARY Retzius-sparing robot-assisted radical prostatectomy is an emerging technique for robotic radical prostatectomy that improves urinary function and quality of life without compromising cancer control.

Abstract
Introduction Preserving continence in patients who underwent radical prostatectomy is of utmost importance. Therefore, modification of surgical technique that would contribute to the regaining of continence with a shortest possible delay after the procedure and adequate evaluation of chances of continence recovery should be considered. Material and methods A PubMed database search was performed to review the current literature concerning the physiology and anatomy of sphincter mechanisms, perioperative risk factors, the effects of surgical techniques on post-prostatectomy continence and post-operative management. Results Modifications of surgical approach with an aim to minimize damage to the sphincter complex, maintenance of maximal urethral length to enable safe anastomosis, and the reconstruction of the urethral support system appears necessary. The patient should also be informed about the chances of regaining continence after surgery. Conclusions There is a need to develop a predictive model to stratify patients according to risk of incontinence and implement adequate action to minimize those risks including preoperative pelvic floor muscle training and/or surgical technique modification.

Abstract
PURPOSE To determine the correlation of preoperative fascia thickness (FT) and intraoperative fascia preservation (FP) with erectile function (EF) after nerve-sparing robot-assisted radical prostatectomy (RARP). METHODS Our analysis included 106 patients, with localized prostate cancer and no erectile dysfunction (ED) before RARP, assessed with preoperative 3 Tesla (3 T) multiparametric magnetic resonance imaging (MRI). FP score was defined as the extent of FP from the base to the apex of the prostate, quantitatively assessed by the surgeon. Median fascia thickness (MFT) per patient was defined as the sum of the median FT of 12 MRI regions. Preserved MFT (pMFT) was the sum of the saved MFT. The percentage of pFMT (ppMFT) was also calculated. Fascia surface (FS) was measured on MRI and it was combined with FP score resulting in preserved FS (pFS) and percentage of pFS (ppFS). RESULTS FP score, pMFT, ppMFT, pFS and ppFS were significantly lower (p < 0.0001) in patients with ED. In the multivariate regression analysis, lower FP score [odds ratio (OR) 0.721, p = 0.03] and lower ppMFT (OR 0.001, p = 0.027) were independent predictors of ED. ROC analysis showed the highest area under the curve for ppMFT (0.787) and FP score (0.767) followed by pMFT (0.755) and ppFS (0.743). CONCLUSIONS MRI-determined periprostatic FT combined with intraoperative FP score are correlated to postprostatectomy EF. Based on the hypothesis that a thicker fascia forms a protective layer for the nerves, we recommend assessing FT preoperatively to counsel men for the odds of preserving EF after RARP.
