Meta-Analysis Review
CONTEXT
Robot-assisted radical prostatectomy (RARP) has largely replaced conventional laparoscopic radical prostatectomy (LRP) even though the costs are significantly higher. Justification for this change is the hope for better postoperative functional results because of better dissection of the neurovascular bundle.
OBJECTIVE
To perform a systematic review and meta-analysis of randomised controlled trials (RCTs) comparing RARP and LRP for the primary outcome of continence (use of 0 pads or 1 safety pad) at 12 mo after surgery.
EVIDENCE ACQUISITION
We searched the CENTRAL, MEDLINE, and Web of Science databases for RCTs comparing RARP versus LRP for adults with localised prostate cancer (PC). Where possible, individual-patient data were obtained. Secondary outcomes were potency for patients potent at baseline; a trifecta of patients continent and potent and no recurrence/further treatment; positive surgical margins; biochemical recurrence; and further treatment for PC. The systematic review was registered prospectively (reviewregistry1190 on www.researchregistry.com/).
EVIDENCE SYNTHESIS
Five RCTs were identified. Three trial teams provided data. For another trial, only published data were available. The fifth trial was terminated prematurely because of insufficient recruitment and thus could not be included. Overall, data for 1205 randomised patients were available. At 12 mo, there was no significant difference between the two groups regarding continence (odds ratio [OR] 1.95, 95% confidence interval [CI] 0.67-5.62). However, at 3 mo and 6 mo there were significant differences in favour of RARP. Significantly more patients who were potent at baseline and underwent a robot-assisted nerve-sparing approach were potent at 12 mo (OR 4.05, 95% CI 1.63-10.09).
CONCLUSION
At 12 mo after surgery there are no differences in continence between RARP and LRP. Short-term continence benefits of RARP were observed. Potent patients undergoing RARP consistently show better potency postoperatively.
PATIENT SUMMARY
We analysed differences between robot-assisted removal of the prostate and conventional keyhole surgery for removal of the prostate. At 12 mo after surgery, there were no differences in continence outcomes between the two approaches. However, patients who were potent at baseline and underwent robot-assisted surgery were more likely to be potent at 12 mo.

Review
PURPOSE OF REVIEW
Urinary incontinence is common postoperative complication following robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa). Despite the increasing adoption of RARP in the treatment of high-risk PCa (HRPC), concerns persist regarding the adequacy of reported continence outcomes in this subgroup. This review aims to illuminate the state of continence recovery in HRPC patients post-RARP.
RECENT FINDINGS
Urinary continence (UC) recovery rates in HRPC was reported to be lower than the intermediate/low-risk counterparts from 6 to 24 months post-RARP. Predictive models showed that age, obesity, race, disease status, and surgical approaches represent predictors of continence recovery. Special techniques like NeuroSAFE technique and Retzius-Sparing approach also play a role in reducing incontinence also in the high-risk scenario.
SUMMARY
RARP for HRPC appears to be associated with worse continence compared with other risk groups. A multimodality approach for prediction and prevention of incontinence after RARP is vital. Further research into this area is necessary to enhance continence recovery outcomes in HRPC patients undergoing RARP.

Review
Macroscopic specimen examination is often critical for accurate histopathology reporting but has generally received insufficient attention and may be delegated to inexperienced staff with limited guidance and supervision. This review discusses issues around macroscopic examination of some common urological specimens; highlighting findings that are critical for patient management and others that are clinically irrelevant. Macroscopic findings are of limited value in completely submitted radical prostatectomy specimens but may be critical in orchidectomy specimens where identification of focal non-seminomatous components can significantly impact patient management. The maximum tumour dimension is often an important prognostic indicator, but specimen dimensions are generally of little clinical utility. Specimens should be carefully examined and judiciously sampled to identify clinically important focal abnormalities such as sarcomatoid change in a renal cell carcinoma and a minor non-seminomatous component in a predominant testicular seminoma. Meticulous macroscopic examination is key as less than 0.2% of the specimen (or macroscopically abnormal area) would be histologically examined even if the entire specimen/abnormal area is submitted for microscopic examination. Retroperitoneal pelvic lymph node dissection specimens for testicular cancer must be handled very differently from other lymph nodal block dissections. Current sampling protocols for transurethral resection of prostate specimens that are based on pre-MRI era data need to be reconsidered because they were specifically designed to detect occult prostate cancer, which would amount to histological cancer screening. Prostatic sampling of cystoprostatectomy specimens should be directed at accurately staging the known bladder cancer rather than detection of incidental prostate cancer.

BACKGROUND
Prostate cancer (PrCa) genomic heterogeneity causes resistance to therapies such as androgen deprivation. Such heterogeneity can be deciphered in the context of evolutionary principles, but current clinical trials do not include evolution as an essential feature. Whether or not analysis of genomic data in an evolutionary context in primary prostate cancer can provide unique added value in the research and clinical domains remains an open question.
METHODS
We used novel processing techniques to obtain whole genome data together with 3D anatomic and histomorphologic analysis in two men (GP5 and GP12) with high-risk PrCa undergoing radical prostatectomy. A total of 22 whole genome-sequenced sites (16 primary cancer foci and 6 lymph node metastatic) were analyzed using evolutionary reconstruction tools and spatio-evolutionary models. Probability models were used to trace spatial and chronological origins of the primary tumor and metastases, chart their genetic drivers, and distinguish metastatic and non-metastatic subclones.
RESULTS
In patient GP5, CDK12 inactivation was among the first mutations, leading to a PrCa tandem duplicator phenotype and initiating the cancer around age 50, followed by rapid cancer evolution after age 57, and metastasis around age 59, 5 years prior to prostatectomy. In patient GP12, accelerated cancer progression was detected after age 54, and metastasis occurred around age 56, 3 years prior to prostatectomy. Multiple metastasis-originating events were identified in each patient and tracked anatomically. Metastasis from prostate to lymph nodes occurred strictly ipsilaterally in all 12 detected events. In this pilot, metastatic subclone content analysis appears to substantially enhance the identification of key drivers. Evolutionary analysis' potential impact on therapy selection appears positive in these pilot cases.
CONCLUSIONS
PrCa evolutionary analysis allows tracking of anatomic site of origin, timing of cancer origin and spread, and distinction of metastatic-capable from non-metastatic subclones. This enables better identification of actionable targets for therapy. If extended to larger cohorts, it appears likely that similar analyses could add substantial biological insight and clinically relevant value.

Meta-Analysis Review
BACKGROUND
Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). We performed this meta-analysis to investigate whether PFME during the entire perioperative period, including before and after RP, can significantly improve the recovery of postoperative UI.
METHODS
We systematically reviewed randomized controlled trials (RCT) from PubMed, Medline, web of science, Cochrane library, and clinicalitrials.com prior to October 2022. Efficacy data were pooled and analyzed using Review Manager Version 5.3. Pooled analyses of urinary incontinence rates 1, 3, 6, and 12 months postoperatively were conducted, using odds ratio (OR) and 95% confidence intervals (CIs).
RESULTS
We included a total of 15 RCT studies involving 2178 patients received RP. Postoperative UI could be improved after 1 month, 3 months and 6 months, and the OR were 0.26 (95%CI:0.15-0.46) 0.30 (95%CI: 0.11-0.80) 0.20 (95%CI: 0.07- 0.56) in postoperative PFME group compared to no PFME group. However, there was no significant difference between the two groups in 12 months after surgery, and the OR was 0.85(95%CI: 0.48,1.51). There were similar results in perioperative PFME group compared to no PFME group with the OR of 0.35 (95%CI: 0.12, 0.98) and 0.40 (95%CI: 0.21, 0.75) in 1 and 3 months after surgery. Our results indicated no significant difference between perioperative PFME group and postoperative PFME group. The OR was 0.58 (95%CI: 0.20-1.71) 0.58 (95%CI:0.20-0.71) and 0.66 (95%CI: 0.32-1.38) in 1, 3 and 6 months after surgery.
CONCLUSION
Application of PFME after RP significantly reduced the incidence of early postoperative UI, and additional preoperative PFME had no significant improvement on the recovery of UI.

Meta-Analysis Review
Efficacy and safety of transurethral thulium laser enucleation versus robot-assisted prostatectomy for large-volume benign prostatic hyperplasia: a systematic review and meta-analysis.
To compare perioperative outcomes between Holmium laser enucleation of the prostate (HoLEP) and robotic-assisted simple pasta-ectomy (RASP)for large-volume benign prostatic hyperplasia(> 80 ml). In August 2023, we undertook a comprehensive search of major global databases including PubMed, Embase, and Google Scholar, focusing solely on articles written in English. Studies that were merely reviews or protocols without any specific published data were omitted. Furthermore, articles that comprised conference abstracts or content not pertinent to our subject of study were also disregarded. To calculate the inverse variances and 95% confidence intervals (CIs) for categorical variables' mean differences, we employed the Cochran-Mantel-Haenszel approach along with random-effects models. The findings were denoted in the form of odds ratios (ORs) and 95% CIs. A p-value less than 0.05 was deemed to indicate statistical significance. Our finalized meta-analysis incorporated six articles, including one randomized controlled trial (RCT) and five cohort studies. These studies accounted for a total of 1218 patients, 944 of whom underwent Holmium Laser Enucleation of the Prostate (HoLEP) and 274 who underwent Robotic-Assisted Simple Prostatectomy (RASP). The pooled analysis from these six papers demonstrated that compared to RASP, HoLEP had a shorter hospital stay, shorter catheterization duration, and a lower blood transfusion rate. Moreover, HoLEP patients exhibited a smaller reduction in postoperative hemoglobin levels. Statistically, there were no significant differences between the two procedures regarding operative time, postoperative PSA, the weight of prostate specimens, IPSS, Qmax, PVR, QoL, and postoperative complications. (HoLEP) and (RASP) are both effective and safe procedures for treating large-volume benign prostatic hyperplasia. HoLEP, with its benefits of shorter catheterization and hospitalization duration, lesser decline in postoperative hemoglobin, and reduced blood transfusion needs, stands as a preferred choice for treating extensive prostate enlargement. However, further validation through more high-quality clinical randomized trials is required.

Review
Against the background of a continuous improvement of established treatment outcomes and the compatibility of health economic considerations, pre- and perioperative processes are constantly being developed and further optimized. In recent years, the concept of prehabilitation has gained increasing importance as a proactive approach to preparing patients for mostly surgical cancer treatment and improving their physical and mental health. Prehabilitation in oncology is a systematic process aimed at improving the physical, psychosocial, and nutritional condition of patients before and during cancer treatment. The goal of prehabilitation is to enhance patients' ability to cope with the physiological stress of cancer treatment and improve their overall health and well-being. In addition, prehabilitation has the potential to reduce costs for the healthcare system.

Meta-Analysis Review
OBJECTIVE
To perform a systematic review and meta-analysis of endoscopic procedures for treating vesico-urethral anastomotic stenosis (VUAS) after prostatectomy, as initial VUAS management remains unclear.
METHODS
A search of the MEDLINE database, the Cochrane database, and clinicaltrials.gov was performed (last search February 2023) using the following query: (['bladder neck' OR 'vesicourethral anastomotic' OR 'anastomotic'] AND ['stricture' OR 'stenosis' OR 'contracture'] AND 'prostatectomy'). The primary outcome was the success rate of VUAS treatment, defined by the proportion (%) of patients without VUAS recurrence at the end of follow-up.
RESULTS
The literature search identified 420 studies. After the screening, 78 reports were assessed for eligibility, and 40 studies were included in the review. The pooled characteristics of the 40 studies provided a total of 1452 patients, with a median (interquartile range [IQR]) follow-up of 23.7 (13-32) months and age of 66 (64-68) years. The overall success rate (95% confidence interval [CI]) of all endoscopic procedures for VUAS treatment was 72.8% (64.4%-79.9%). Meta-regression models showed a negative influence of radiotherapy on the overall success rate (P = 0.012). After trim-and-fill (addition of 10 studies), the corrected overall success rate (95% CI) was 62.9% (53.6%-71.4%).
CONCLUSION
This first meta-analysis of endoscopic treatment success rate after VUAS reported an overall success rate of 72.8%, lowered to 62.9% after correcting for significant publication bias. This study also highlighted the need for a more thorough reporting of post-prostatectomy VUAS data to understand the treatment pathway and provide higher-quality evidence-based care.

Review
Longevity with localized prostate cancer (PCa) has been achieved, and the contribution of robot-assisted radical prostatectomy (RARP) to cancer control is evident. The next step to investigate in the treatment of localized PCa is improvement of the quality of life (QOL) after RARP. Erectile dysfunction has been considered a major surgical complication, and patient satisfaction after RARP has not improved despite the development of nerve preservation and penile rehabilitation. To comprehensively understand sexual dysfunction after RARP, we must investigate other complications with regard to sexual health, including low sexual desire, disturbed orgasmic function (i.e., anejaculation, orgasm intensity, painful orgasm, and climacturia), shortening of penile length, penile curvature (Peyronie's disease) and unique psychological alterations after the diagnosis of PCa, which are neglected side effects after prostatectomy. In this context, routine evaluation of erectile function by the International Index of Erectile Function only is not sufficient to understand patients' difficulties. A questionnaire is just one way of enabling patients to evaluate their pre- and postoperative concerns; listening to patients face-to-face is warranted to detect symptoms. Understanding the relationship between symptoms and preserved nerve localization can ultimately provide an individualized nerve-sparing procedure and improve patient satisfaction after RARP. In combination with psychological counseling, including the partner and medical treatment, such as testosterone replacement, it is time to reconsider ways to improve sexual dysfunction after RARP.

15-year biochemical failure, metastasis, salvage therapy, and cancer-specific and overall survival rates in men treated with robotic radical prostatectomy for PSA-screen detected prostate cancer.
BACKGROUND
An informed decision regarding a treatment option requires data on its long-term efficacy and side-effect profile. While the side-effects of robotic radical prostatectomy have been well-quantified, the data on its long-term efficacy are lacking. We here provide 15-year oncological outcomes of clinically-localized prostate cancer (CLPCa) patients treated with robot-assisted laparoscopic prostatectomy (RALP).
METHODS
We treated 1,807 men with CLPCa with RALP between 2001 and 2005 and prospectively collected follow-up data through 2020. We examined the rates of biochemical failure (BCF), metastatic progression, secondary therapy use, PCa-specific mortality (PCSM), and overall survival (OS) using Kaplan-Meier and competing-risk cumulative incidence methods as appropriate.
RESULTS
The median follow-up was 14.1 years. Six hundred eight and 312 men had D'Amico intermediate- and high-risk disease, respectively. Overall, the 15-year rates of BCF, metastasis, secondary therapy use, PCSM, and OS were 28.1%, 4.0%, 16.3%, 2.5%, and 82.1%, respectively. The rates of oncologic failure increased with increasing D'Amico (preoperative) and Diaz (postoperative) risk scores - BCF, metastasis, and PCSM rates in D'Amico low-, intermediate-, and high-risk groups at 15-years were 15.2%, 38.3%, and 44.1% [BCF], 1.1%, 4.1%, and 13.0% [metastasis], and 0.5%, 3.4%, and 6.6% [PCSM], respectively, and in Diaz risk groups 1, 2, 3, 4, and 5 were 5.5%, 20.6%, 41.8%, 66.9%, and 89.2% [BCF], 0%, 0.5%, 3.2%, 20.5%, and 60.0% [metastasis], and 0%, 0.8%, 0.6%, 13.5%, and 37.5% [PCSM], respectively. The OS rates in D'Amico low-to-high and Diaz 1-to-5 risk groups at 15-years were 85.9%, 78.6%, and 75.2%, and 89.4%, 83.2%, 80.6%, 67.2%, and 23.4%, respectively.
CONCLUSIONS
Men diagnosed with clinically-localized prostate cancer in the contemporaneous PSA-screening era and treated with RALP achieve durable long-term oncological control. The data reported here (in a risk-stratified manner) represent the longest follow-up after robotic radical prostatectomy, and as such, should be of value when counseling patients regarding expected oncologic outcomes from RALP.
