Meta-Analysis Review
We conducted a systematic review and meta-analysis to investigate the role of alcohol consumption with the prognosis of prostate cancer (PCa). Published reports were gathered on 15 October 2022, from PUBMED/MEDLINE and EMBASE. We found 19 independent eligible studies on the association between consumption of alcoholic beverages and the risk of fatal PCa (n = 5), PCa mortality (n = 5) in healthy subjects, and PCa patients' survival (n = 7) or surrogates thereof (n = 2). We used random effects meta-analysis to obtain a summary risk estimate (SRE) and 95% confidence intervals (95%CI) for incidence of fatal PCa and PCa mortality. The meta-analysis revealed no association between alcohol consumption and fatal prostate cancer incidence risk in healthy subjects with an indication for publication bias, but omitting the study that mainly increased the between-study heterogeneity, the SRE becomes significant (SRE 1.33, 95%CI 1.12-1.58), and the heterogeneity disappeared ( = 0%) with no indication of publication bias. No association of alcohol consumption was found with mortality risk in PCa patients (SRE 0.97, 95%CI 0.92-1.03) and PCa mortality risk in healthy subjects (SRE 1.03, 95%CI 0.82-1.30). In conclusion, this study suggests that there is some evidence of an association between high alcohol consumption and an increased risk of incidence of fatal prostate cancer in healthy subjects. Given the inconsistencies this result warrants further confirmation.

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.

Review
Male genital schistosomiasis (MGS) may result in eggs lodged in the prostate causing persistent inflammation that may play a major role in prostate carcinogenesis. Globally, prostate cancer (PCa) is one of the most common cancers and the global distribution of PCa overlaps with that of schistosomiasis infections, suggesting a probable causal relationship. Objectives of this review were to assess evidence of co-existence of schistosomiasis and PCa and possible causal association between the two diseases. Relevant literature published between 1950 and 2019 yielded 20 publications on schistosomiasis and PCa co-existence. Schistosoma (S.) haematobium and S. mansoni were associated with MGS manifestation and mostly prostate adenocarcinoma diagnosis. Effects of prostatic MGS infection progressed over time with high Schistosoma egg burden thought to contribute to the development of PCa. Causal association and mechanistic pathways of MGS on PCa development and the role of Schistosoma eggs on the development of PCa remains unestablished.

Meta-Analysis
AIMS
Data on the association between nut consumption and prostate cancer risk are conflicting. Therefore, this systematic review and dose-response meta-analysis aimed to summarize available findings from observational studies on the associations of nut intake with risk of total, advanced, non-advanced, and fatal prostate cancers.
DATA SYNTHESIS
We searched the online databases of PubMed, Scopus, and Web of Science as well as Google Scholar using appropriate keywords to identify eligible articles up to September 2022. In total, 11 articles with a total sample size of 287,786 participants and 32,213 cases of prostate cancer were included in the current systematic review and meta-analysis. By comparing the highest and lowest intake of total nuts, pooled relative risks (RRs) and 95% confidence intervals (95% CIs) for total, advanced, non-advanced, and fatal prostate cancers were 0.94 (95% CI: 0.85-1.04, P = 0.22), 1.10 (95% CI: 0.98-1.24, P = 0.12), 0.97 (95% CI: 0.85-1.11, P = 0.69), 0.97 (95% CI: 0.79-1.18, P = 0.73), respectively, which indicated non-significant inverse associations for total, non-advanced, and fatal prostate cancers and a non-significant positive association for advanced prostate cancer. In the dose-response analyses, we found no evidence of a linear or non-linear association between total nut intake and prostate cancer risk. Data on other types of nuts, including walnut, tree nuts, peanut, and peanut butter, were not sufficient for performing a meta-analysis.
CONCLUSION
We found no significant association between nut intake and risk of total, advanced, non-advanced, and fatal prostate cancer. Further studies are required to confirm our findings.

Meta-Analysis Review
PURPOSE
To review and compare the effectivity of novel minimally invasive treatments (MITs) to transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms (LUTS) in men.
METHODS
Medline, Embase, and Cochrane databases were searched from January 2010 to December 2022 for randomized controlled trials (RCTs) evaluating MITs, compared to TURP or sham, in men with LUTS. Studies were assessed by risk of bias tool, and evidence by GRADE. Functional outcomes by means of uroflowmetry and IPSS were the primary outcomes, safety and sexual function were secondary outcomes. As part of this review, a network meta-analysis (NMA) was conducted. MITs were ranked based on functional outcome improvement probability.
RESULTS
In total, 10 RCTs were included, evaluating aquablation, prostatic urethral lift, prostatic artery embolization (PAE), convective water vapor thermal treatment or temporary implantable nitinol device. All MITs showed a better safety profile compared to TURP. Functional outcome improvement following aquablation were comparable to TURP. In the NMA, aquablation was ranked highest, PAE followed with the second highest probability to improve functional outcomes. Other novel MITs resulted in worse functional outcomes compared to TURP. Level of evidence was low to very low.
CONCLUSIONS
Five MITs for treatment of LUTS were identified. Aquablation is likely to result in functional outcomes most comparable to TURP. Second in ranking was PAE, a technique that does not require general or spinal anesthesia. MITs have a better safety profile compared to TURP. However, due to high study heterogeneity, results should be interpreted with caution.

Meta-Analysis
Transurethral resection of the prostate (TURP) is the gold-standard classical method for the treatment of benign prostatic hyperplasia (BPH). In minimally invasive surgery, holmium laser enucleation of the prostate (HoLEP) is considered an alternative option. In this systematic review and meta-analysis, we aimed to comprehensively evaluate the advantages and disadvantages of TURP and HoLEP the treating BPH. We comprehensively searched PubMed, Cochrane Library, EMBASE, and Web of Science databases for all randomized controlled trials published before 1 December 2022 comparing HoLEP and TURP. The study protocol is registered on INPLASY (DOI: 10.37766/inplasy2023.5.0065). Compared with TURP, HoLEP required longer operation time but shorter catheter duration, hospital stay, and bladder irrigation time, as well as less postoperative irrigation. With HoLEP, maximum urinary flow rate at 12 and 24 months after surgery; post-void residual volume at 1, 6, and 12 months; and International Prostate Symptom Score at 12 months after surgery were superior to those with TURP. HoLEP was associated with significantly lower risk of hyponatremia, blood transfusion, and urethral stricture but greater risk of postoperative dysuria. Compared with TURP, HoLEP had better curative efficacy at 6, 12, and 24 months after operation and lower incidence of adverse events in patients with BPH.

Meta-Analysis
BACKGROUND
Emerging researches has evaluated whether fruit and vegetable consumption reduce the risk of prostate cancer. However, the conclusions of published articles remained confusing. Thus, we conducted an updated systematic review and meta-analysis to confirm the relationship of fruit and vegetable consumption and the risk of prostate cancer.
METHOD
We searched PubMed, EMBASE, Web of Science and Chinese National Knowledge Infrastructure (CNKI) up to September 1, 2020. We finally included 17 cohort studies related to fruit or vegetable intake after rigid quality assessment and checking references of the retrieved articles and relevant reviews. Newcastle-Ottawa scale was adopted to assess the quality of studies and random effect model with RR and 95% CI were used to assess the risk.
RESULTS
No significant relationship was found between fruit consumption (RR = 1.00, 95% CI = 0.94-1.05) and vegetable consumption (RR = 0.98, 95% CI = 0.94-1.02) and the risk of prostate cancer. No significant heterogeneity or publication bias was identified.
CONCLUSION
Our updated meta-analysis demonstrated that fruit and vegetable consumption can barely reduce the risk of prostate cancer with several limitations. Further clinical and basic researches are eagerly awaited to confirm our results and clarify the potential biological mechanisms.

Meta-Analysis Review
Peri- and post-operative outcomes, complications, and functional results amongst different modifications of endoscopic enucleation of the prostate (EEP): a systematic review and meta-analysis.
PURPOSE
To investigate and assess outcomes, complications, and functional results amongst different modifications of endoscopic enucleation of the prostate (EEP).
METHODS
We conducted a systematic review and meta-analysis according to the PRISMA checklist. We searched the Medline, Cochrane, and Embase databases. We included only randomised-controlled trials (RCT) comparing modifications of EEPs and assessed the risk of bias (RoB).
RESULTS
Seven RCTs were included in the study. Overall, 1266 patients were treated with Holmium laser enucleation of the prostate (HoLEP) and 80 patients with thulium laser vapo-enucleation of the prostate (ThuVEP). The operative time during pulse shape-modified HoLEP was shorter when compared to standard pulse HoLEP (MD 18.08 min, 95% CI 8.11-28.05 min, p = 0.0004). The decrease in haemoglobin was significantly lower for two-lobe HoLEP when compared to three-lobe HoLEP (MD 0.16 g/dl, 95% CI 0.22-0.1 g/dl, p < 0.00001). Virtual Basket (VB) HoLEP showed a smaller haemoglobin decrease when compared to standard pulse HoLEP (1.12 ± 1.78 vs. 2.54 ± 1.23 g/dl, p = 0.03). When directly comparing one- vs. two- vs. three-lobe HoLEP, surgical time (p < 0.001) and enucleation efficiency (p = 0.006) were significantly different and favouring one- and two-lobe HoLEP in the study with the largest patient population included. No significant differences for complications were observed; however, Clavien-Dindo IVa events were reported for two patients.
CONCLUSION
All variations of EEP improve symptoms and functional parameters with a low incidence of high-grade complications. One- and two-lobe approaches and pulse shape-modified HoLEP seem to be beneficial in terms of operative time and blood loss.

Review
This study aims to conduct a systematic review of full economic analyses of robotic-assisted surgery (RAS) in adults' thoracic and abdominopelvic indications. Authors used Medline, EMBASE, and PubMed to conduct a systematic review following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines. Fully published economic articles in English were included. Methodology and reporting quality were assessed using standardized tools. Majority of studies (28/33) were on oncology procedures. Radical prostatectomy was the most reported procedure (16/33). Twenty-eight studies used quality-adjusted life years, and five used complication rates as outcomes. Nine used primary and 24 studies used secondary data. All studies used modeling. In 81% of studies (27/33), RAS was cost-effective or potentially cost-effective compared to comparator procedures, including radical prostatectomy, nephrectomy, and cystectomy. Societal perspective, longer-term time-horizon, and larger volumes favored RAS. Cost-drivers were length of stay and equipment cost. From societal and payer perspectives, robotic-assisted surgery is a cost-effective strategy for thoracic and abdominopelvic procedures.Clinical trial registration This study is a systematic review with no intervention, not a clinical trial.

Meta-Analysis Review
PURPOSE
There are limited pooled data showing the impact of visceral metastasis on oncologic outcomes in metastatic prostate cancer patients treated with combination systemic therapies. We aimed to analyze and compare the efficacy of combination systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer with or without visceral metastasis.
MATERIALS AND METHODS
Three databases were queried in July 2022 for randomized, controlled trials analyzing metastatic prostate cancer patients treated with combination systemic therapy (androgen receptor signaling inhibitor and/or docetaxel plus androgen deprivation therapy) to standard of care. We analyzed the association between presence of visceral metastases and efficacy of systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer patients. The main and secondary outcomes of interest were overall survival and progression-free survival, respectively. Formal meta-analysis using fixed-effect model and network meta-analysis using random-effect model were conducted. We followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) and AMSTAR (A MeaSurement Tool to Assess systematic Reviews) guidelines.
RESULTS
Overall, 12 and 8 randomized, controlled trials were included for systematic review and meta-analyses/network meta-analyses, respectively. In metastatic hormone-sensitive prostate cancer patients, adding androgen receptor signaling inhibitor to standard of care improved overall survival in patients with visceral metastasis (pooled HR: 0.77, 95% CI: 0.64-0.94) as well as in those without (pooled HR: 0.66, 95% CI: 0.60-0.72; no differences in both across- and within-trial approach; = .13 and = .06, respectively). On the other hand, the progression-free survival benefit from androgen receptor signaling inhibitor + androgen deprivation therapy was significantly lower in patients with visceral metastasis using across-trial approach ( = .03), while it did not reach statistical significance using within-trial approach ( = .14). Analysis of treatment ranking in metastatic hormone-sensitive prostate cancer showed that darolutamide + docetaxel + androgen deprivation therapy had the highest likelihood of improved overall survival irrespective of visceral metastasis. In post-docetaxel metastatic castration-resistant prostate cancer patients, adding androgen receptor signaling inhibitor to androgen deprivation therapy significantly improved overall survival in both patients with visceral metastasis (pooled HR: 0.79, 95% CI: 0.63-0.98) and those without (pooled HR: 0.63, 95% CI: 0.55-0.72). No randomized, controlled trials reported the differential oncologic outcomes stratified by lung vs liver metastases.
CONCLUSIONS
Despite aggressive clinical behavior and worse trajectory of metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer with visceral metastasis, the effectiveness of novel systemic therapies is similar in both metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer patients with and without visceral metastasis. Further well-designed studies with detailed visceral metastatic sites and number will enrich the clinical decision-making.
