Introduction: Robotic assisted radical prostatectomy (RARP) is getting more and more popular becoming the most common radical prostatectomy technique. Unfortunately, a not negligible proportion of patients in whom RARP is performed experience urinary incontinence. We aimed to systematically review the current literature evidence on urinary incontinence conservative treatment after RARP.

Edidence aquisition: A systematic literature review search using PubMed (Medline), Scopus, and Web of Science databases was performed in December 2019. PRISMA guidelines have been adopted. Population consisted of patients with urinary incontinence after RARP (P), conservative intervention was considered of interest (I). No comparator was considered mandatory (C). Outcomes of interest were the recovery of continence and quality of life (O).

Evidedence synthesis: Six studies were included. Four of them investigated the use of pelvic floor muscle training (PFMT). PFMT improved pelvic muscle strength. Continence recovery was faster when guided PFMT was adopted. Moreover, two studies tested the effect of solifenacin on urinary incontinence. One of them, a randomized clinical trial, failed to show shorter time to continence in solifenacin group compared to placebo.

Conclusions: The use of pads is associated with a detrimental effect on quality of life thus active treatments for UI post-RARP are warranted. PFMT has the main advantage to shorten the time for recovery. The use of solifenacin seems to not offer striking advantages in UI following RARP. Future studies should focus on testing the efficacy of these treatments when used after robotic vs. open radical prostatectomy.

Introduction: We aimed to compare the perioperative, pathological and oncological outcomes of patients undergoing extracorporeal urinary diversion (EUD) and intracorporeal urinary diversion (IUD) following robot-assisted radical cystectomy (RARC).

Evidence acquisition: Multiple scientific databases were searched up to January 2020 for comparative studies comparing IUD and EUD. The data was analyzed by Review Manager 5.3.

Evidence synthesis: A total of 9 observational studies comprising 3582 patients were included in the final analysis. We observed that IUD approach were significantly associated with lower estimated blood loss (EBL) (MD: -90.50, 95% CI: -131.26 to -49.74, P<0.0001), fewer gastrointestinal complications (RR: 0.65; 95% CI: 0.45 to 0.93; P=0.02), and lower risk of uretero-ileal anastomotic stricture (RR: 0.36; 95% CI: 0.14 to 0.91; P=0.03). We did not detect significant difference in terms of length of stay (P=0.14), operative time (P=0.55), blood transfusion (P=0.10), 30-day complication (P=0.50), 90-day complication (P=0.40), 30-day readmission (P=0.12), 90-day readmission (P=0.95), positive surgical margins (P=0.42), lymph node yield (P=0.13), 30-day reoperation (P=0.11) and 90-day mortality (0.27) between IUD and EUD.

Conclusions: The approach of urinary diversion does not have a considerable impact on pathological, perioperative and oncological outcomes in patients undergoing RARC. The benefits conferred by IUD are lower EBL, lower risk of gastrointestinal complications, and uretero-ileal anastomotic stricture. Subgroup analysis of patients with ileal conduit showed similar results on perioperative and complication outcomes. Well-designed trials conducted by large volumes and experienced surgeons, and reporting complications based on standardized methodology are still warranted.

Introduction: The aim of this review was to summarize the available evidence on the role of metastasis-directed therapy (MDT) and/or prostate-targeted therapy (PTT) in the setting of oligometastatic prostate cancer (PCa).

Evidence acquisition: We searched PubMed, the Web of Science, and the Cochrane Library databases. The following keywords were used: ("prostate cancer" OR "prostate carcinoma" OR "prostate neoplasm" OR "prostate tumor") AND ("oligometastatic" OR "oligometastasis" OR "PSMA") AND ("surgery" OR "prostatectomy" OR "radical prostatectomy" OR "cytoreductive" OR "local treatment" OR "radiotherapy" OR "stereotactic" OR "stereotaxic") AND ("survival" OR "mortality").

Evidence synthesis: After evaluating the selection criteria, 81 studies were evaluated for our endpoints. We included 22 studies for PTT of synchronous mPCa. There have been no randomized studies on cytoreductive prostatectomy (cRP). Four prospective studies showed that cRP was feasible but did not contribute to a positive effect on overall survival (OS). Regarding PTT-radiotherapy, two randomized controlled phase 3 trials showed that OS was improved in men with a low metastatic burden. Regarding MDT of metachronous lymph node recurrence, we included 29 retrospective studies. For MDT of oligometastases, we included 30 studies. One randomized phase 2 trial showed that androgen deprivation therapy-free survival improved with stereotactic body radiation therapy compared to that with surveillance; however, benefits on OS remain unclear.

Conclusions: We performed a comprehensive overview of the current literature on MDT and PTT. The feasibility of MDT and PTT is supported by several retrospective studies. Nevertheless, there remains a lack of high-quality trials to prove its survival benefits. Results from ongoing prospective trials data are awaited.

Introduction: Percutaneous nephrolithotomy (PCNL) is a minimally invasive approach used for large kidney stones. Although tranexamic acid (TA) has the property of reducing perioperative bleeding, the effect of this drug on PCNL is equivocal. This meta-analysis was conducted to determine the efficacy and safety of TA in preventing hemorrhagic complications, transfusion requirements and other perioperative outcomes during PCNL with available randomized-controlled trials (RCTs).

Evidence acquisition: We performed a systematic review of the literature according to Cochrane guidelines for studies comparing TA and normal saline. All studies reporting the outcomes of interest were included. The data analysis was completed using the Cochrane Collaboration's software RevMan 5.3.

Evidence synthesis: Data from three RCTs on 570 patients were included in the final meta-analysis. Patients receiving TA experienced less blood loss (MD: -0.82; 95% CI: -1.24 to -0.40; P=0.0001), fewer transfusion requirements (OR: 0.40; 95% CI: 0.01-0.76; P=0.005), lower minor complication rate (OR:0.51, 95% CI: 0.32-0.80, P=0.003), fewer major complication rate (OR:0.31, 95% CI: 0.11-0.88, p=0.03), shorter operative time (SMD: -0.39; 95% CI: -0.75 to -0.02; P=0.04) and less length of stay (LOS) (SMD: -0.68; 95% CI: -1.01 to -0.35; P<0.0001) than their counterparts during PCNL with statistically significant P value and no significant between-study heterogeneity except for LOS and operative time.

Conclusions: Our work assessing the use of TA in the clinical management of patients undergoing PCNL indicated promising results. Further well-designed trials are warranted to determine the optimal dose and indications of this drug in practice.

Background: The aim of the present study was to compare the surgical outcomes of retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and open retropubic radical prostatectomy (ORP).

Methods: We included patients with clinically localized prostate cancer who underwent RS-RARP or ORP and met our inclusion criteria. We compared the perioperative, oncological, and continence outcomes between both surgical approaches. Continence function was assessed using the validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form. Continence was defined as using 0-1 safety pad per day. Biochemical recurrence (BCR) was defined as two consecutive rises in serum PSA more than 0.2 ng/mL. Events of local recurrence, distant metastasis, and cancer death were reported and compared using Kaplan-Meier survival analysis.

Results: Between 1 June 2013 and 1 October 1 2016, 184 men were enrolled, of whom 125 underwent RS-RARP and 59 underwent ORP. Baseline demographic and pathological characteristics were similar between both groups (P>0.05). Patients in RS-RARP group had significantly lower blood loss, fewer transfusion rates, lower VAS score, and shorter hospital stay than patients in ORP group (P<0.05). Major complications (≥grade 3b) did not differ between both groups (P=0.121). Positive surgical margins were 28.8% and 24.8% in ORP and RS-RARP, respectively (P=0.494). The BCR free-survival rates in ORP and RS-RARP at 1-year was 87.3% and 92.3%, respectively (Log-rank, P=0.740). At 1-, 6-, and 12-month after surgery, 42.4%, 79.7%, and 84.7% of men undergoing ORP were continent, compared with 72.8%, 90.4%, and 92% undergoing RS-RARP, respectively. Men in RS-RARP group achieved faster recovery of urinary continence compared to men in ORP group (Log-rank, P=0.001).

Conclusions: RS-RARP had better perioperative outcomes and faster recovery of urinary continence compared with ORP. Short-term oncological outcomes were comparable between both surgical approaches.
