Meta-Analysis Review
CONTEXT
The safety and feasibility of robotic-assisted radical prostatectomy (RARP) compared with retropubic radical prostatectomy(RRP) is debated. Recently, a number of large-scale and high-quality studies have been conducted.
OBJECTIVE
To obtain a more valid assessment, we update the meta-analysis of RARP compared with RRP to assessed its safety and feasibility in treatment of prostate cancer.
METHODS
A systematic search of Medline, Embase, Pubmed, and the Cochrane Library was performed to identify studies that compared RARP with RRP. Outcomes of interest included perioperative, pathologic variables and complications.
RESULTS
78 studies assessing RARP vs. RRP were included for meta-analysis. Although patients underwent RRP have shorter operative time than RARP (WMD: 39.85 minutes; P < 0.001), patients underwent RARP have less intraoperative blood loss (WMD = -507.67ml; P < 0.001), lower blood transfusion rates (OR = 0.13; P < 0.001), shorter time to remove catheter (WMD = -3.04day; P < 0.001), shorter hospital stay (WMD = -1.62day; P < 0.001), lower PSM rates (OR:0.88; P = 0.04), fewer positive lymph nodes (OR:0.45;P < 0.001), fewer overall complications (OR:0.43; P < 0.001), higher 3- and 12-mo potent recovery rate (OR:3.19;P = 0.02; OR:2.37; P = 0.005, respectively), and lower readmission rate (OR:0.70, P = 0.03). The biochemical recurrence free survival of RARP is better than RRP (OR:1.33, P = 0.04). All the other calculated results are similar between the two groups.
CONCLUSIONS
Our results indicate that RARP appears to be safe and effective to its counterpart RRP in selected patients.

Meta-Analysis
Comparing prostatic artery embolization to surgical and minimally invasive procedures for the treatment of benign prostatic hyperplasia: a systematic review and meta-analysis.
BACKGROUND
To summarize current evidence to report a comparative systematic review and meta-analysis of prostatic artery embolization (PAE) with transurethral resection of the prostate (TURP) and open simple prostatectomy (OSP) for the treatment of benign prostatic hyperplasia (BPH).
METHODS
A systematic literature search was performed to identify studies published from inception until August 2021. The search terms used were (prostate embolization OR prostatic embolization) AND (prostatic hyperplasia OR prostatic obstruction) as well as the abbreviations of PAE and BPH. Risk of bias was assessed using the Cochrane Risk of Bias tool for randomized controlled trials (RCTs) and the Risk of Bias in Non-randomized Studies-of Interventions (ROBINS-I) tool for observational studies. Random-effects meta-analysis was performed using Revman 5.4.
RESULTS
Seven studies were included with 810 patients: five RCTs and one observational study compared PAE with TURP, and one observational study compared PAE with OSP. The included studies had considerable risk of bias concerns. TURP and OSP were associated with more statistically significant improvements in urodynamic measures and BPH symptoms compared to PAE. However, PAE seems to significantly improve erectile dysfunction compared to OSP and improve other outcome measures compared to TURP, although not significantly. PAE appeared to reduce adverse events and report more minor complications compared with TURP and OSP, but it is unclear whether PAE is more effective in the long-term.
CONCLUSION
PAE is an emerging treatment option for patients with symptomatic BPH who cannot undergo surgery or have undergone failed medical therapy. Overall, PAE groups reported fewer adverse events. Future ongoing and longer-term studies are needed to provide better insight into the benefit of PAE compared to other treatment options.

Meta-Analysis Review
BACKGROUND
Prostate cancer is the second most frequently diagnosed cancer and the sixth leading cause of cancer death in males. A systematic review of randomised controlled trials (RCTs) of radiotherapy and other non-pharmacological management options for localised prostate cancer was undertaken.
METHODS
A search of thirteen databases was carried out until March 2014. RCTs comparing radiotherapy (brachytherapy (BT) or external beam radiotherapy (EBRT)) to other management options i.e. radical prostatectomy (RP), active surveillance, watchful waiting, high intensity focused ultrasound (HIFU), or cryotherapy; each alone or in combination, e.g. with adjuvant hormone therapy (HT), were included. Methods followed guidance by the Centre for Reviews and Dissemination and the Cochrane Collaboration. Indirect comparisons were calculated using the Bucher method.
RESULTS
Thirty-six randomised controlled trials (RCTs, 134 references) were included. EBRT, BT and RP were found to be effective in the management of localised prostate cancer. While higher doses of EBRT seem to be related to favourable survival-related outcomes they might, depending on technique, involve more adverse events, e.g. gastrointestinal and genitourinary toxicity. Combining EBRT with hormone therapy shows a statistically significant advantage regarding overall survival when compared to EBRT alone (Relative risk 1.21, 95% confidence interval 1.12-1.30). Aside from mixed findings regarding urinary function, BT and radical prostatectomy were comparable in terms of quality of life and biochemical progression-free survival while favouring BT regarding patient satisfaction and sexual function. There might be advantages of EBRT (with/without HT) compared to cryoablation (with/without HT). No studies on HIFU were identified.
CONCLUSIONS
Based on this systematic review, there is no strong evidence to support one therapy over another as EBRT, BT and RP can all be considered as effective monotherapies for localised disease with EBRT also effective for post-operative management. All treatments have unique adverse events profiles. Further large, robust RCTs which report treatment-specific and treatment combination-specific outcomes in defined prostate cancer risk groups following established reporting standards are needed. These will strengthen the evidence base for newer technologies, help reinforce current consensus guidelines and establish greater standardisation across practices.

Meta-Analysis Review
OBJECTIVE
Conflicting data have been reported regarding the association between perioperative blood transfusion (PBT) and clinical outcomes for prostate cancer patients. We conducted a systematic review and meta-analysis to evaluate the impact of PBT on cancer survival and recurrence for patients who underwent radical prostatectomy (RP).
METHODS
A systematic review of PubMed, EMBASE, and Cochrane libraries was performed to identify all eligible studies that evaluate the association between PBT and clinical outcomes for prostate cancer patients undergoing RP. The analyzed outcomes were overall survival (OS) and recurrence-free survival (RFS) at 3, 5, and 10 years.
RESULTS
A total of eight articles met our criteria. Meta-analysis indicated that prostate cancer patients with PBT had decreased OS (hazard ratio [HR] =1.51, 95% confidence interval [CI], 1.22-1.85, P < 0.01; HR = 1.57, 95% CI, 1.33-1.85, P < 0.01; HR = 1.55, 95% CI, 1.03-2.33, P = 0.04) and RFS (HR = 1.67, 95% CI, 1.37-2.04, P < 0.01; HR = 1.42, 95% CI, 1.23-1.63, P < 0.01; HR = 1.37, 95% CI, 1.03-1.83, P = 0.03) at 3, 5, and 10 years after surgery compared with those without PBT.
CONCLUSIONS
The findings from the current meta-analysis demonstrate that PBT was associated with adverse survival and recurrence outcomes for prostate cancer patients undergoing RP.

With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help clinicians recognize and properly treat patients suffering from ED. One of the most reliable treatments for ED is penile prosthetic surgery. Since the introduction of the penile prosthesis (PP) in the early seventies, this surgical procedure has improved the lives of thousands of men, with reliable and satisfactory results. The aim of this review article is to characterize the epidemiology of men undergoing penile prosthetic surgery, with a discussion about the most common conditions involved in the development of ED, and that ultimately drive patients into electing to undergo PP placement.

Review
PURPOSE OF REVIEW
Bladder neck preservation (BNP) during radical prostatectomy (RP) has been proposed as a method to improve early recovery of urinary continence after radical prostatectomy. However, there is concern over a possible increase in the risk of positive surgical margins and prostate cancer recurrence rate. A recent systematic review and meta-analysis reported improved early recovery and overall long-term urinary continence without compromising oncologic control. The aim of our study was to perform a critical review of the literature to assess the impact on bladder neck and base margins after bladder neck sparing radical prostatectomy.
EVIDENCE ACQUISITION
We carried out a systematic review of the literature using Pubmed, Scopus and Cochrane library databases in May 2017 using medical subject headings and free-text protocol according to PRISMA guidelines. We used the following search terms: bladder neck preservation, prostate cancer, radical prostatectomy and surgical margins. Studies focusing on positive surgical margins (PSM) in bladder neck sparing RP pertinent to the objective of this review were included.
EVIDENCE SYNTHESIS
Overall, we found 15 relevant studies reporting overall and site-specific positive surgical margins rate after bladder neck sparing radical prostatectomy. This included two RCTs, seven prospective comparative studies, two retrospective comparative studies and four case series. All studies were published between 1993 and 2015 with sample sizes ranging between 50 and 1067. Surgical approaches included open, laparoscopic and robot-assisted radical prostatectomy. The overall and base-specific PSM rates ranged between 7-36% and 0-16.3%, respectively. Mean base PSM was 4.9% in those patients where bladder neck sparing was performed, but only 1.85% in those without sparing. Bladder neck preservation during radical prostatectomy may increase base-positive margins. Further studies are needed to better investigate the impact of this technique on oncological outcomes. A future paradigm could include modification of intended approach to bladder neck dissection when anterior base lesions are identified on pre-operative MRI.

Meta-Analysis Review
INTRODUCTION
The aim of our work was to evaluate the role of multi-parametric magnetic resonance imaging (mpMRI) in detection and management of prostate cancer (PC); specifically investigating the efficacy of mpMRI-based biopsy techniques in terms of diagnostic yield of significant prostate neoplasm and the improved management of patients who choose conservative treatments or active surveillance.
EVIDENCE ACQUISITION
A systematic and critical analysis through Medline, Embase, Scopus and Web of Science databases was carried out in March 2016, following the PRISMA ("Preferred Reporting Items for Systematic Reviews and Meta-Analyses") statement. The search was conducted using the following key words: "MRI/TRUS-fusion biopsy," "PIRADS," "prostate cancer," "magnetic resonance imaging (MRI)," "multiparametric MRI (mpMRI)," "systematic prostate biopsy (SB)," "targeted prostate biopsy (TPB)." English language articles were reviewed for inclusion ability.
EVIDENCE SYNTHESIS
Sixty-six studies were selected in order to evaluate the characteristics and limitations of traditional sample biopsy, the role of mpMRI in detection of PC, specifically the increased degree of diagnostic accuracy of targeted prostate biopsy compared to systematic biopsy (12 cores), and to transperineal saturation biopsies with trans-rectal ultrasound (TRUS) only. MpMRI can detect index lesions in approximately 90% of cases when compared to prostatectomy specimen. The diagnostic performance of biparametric MRI (T2w + DWI) is not inferior to mpMRI, offering valid options to diminish cost- and time-consumption. Since approximately 10% of significant lesions are still MRI-invisible, systematic cores biopsy seem to still be necessary. The analysis of the different techniques shows that in-bore MRI-guided biopsy and MRI/TRUS-fusion-guided biopsy are superior in detection of significant PC compared to visual estimation alone. MpMRI proved to be very effective in active surveillance, as it prevents underdetection of significant PC and it assesses low-risk disease accurately. In higher-risk disease, presurgical MRI may change the clinically-based surgical plan in up to a third of cases.
CONCLUSIONS
Targeted prostate biopsy, guided by mpMRI, is able to improve diagnostic accuracy and to reduce the detection of insignificant PC. Since the negative predictive value (NPV) of mpMRI is still imperfect, systematic cores biopsy should not be omitted for optimal staging of disease. A process of a progressive and periodic evolution in the detection and radiological classification of prostate lesions (such as PIRADS), is still needed in patients in active surveillance and in radical prostatectomy planning.

Comparative Study Meta-Analysis Review
BACKGROUND
Laparoscopy is a revolutionary technique in modern surgery. However, the comparative efficacy between two-dimensional laparoscopy and three-dimensional laparoscopy remains in uncertainty. Therefore we performed this systematic review and meta-analysis in order to seek for answers.
METHODS
Databases of PubMed, Web of Science, EMBASE and Cochrane Library were carefully screened. Clinical trials comparing two-dimensional versus three-dimensional laparoscopy were included for pooled analysis. Observational and randomized trials were methodologically appraised by Newcastle-Ottawa Scale and Revised Jadad's Scale respectively. Subgroup analyses were additionally conducted to clarify the potential confounding elements. Outcome stability was examined by sensitivity analysis, and publication bias was analyzed by Begg's test and Egger's test.
RESULTS
21 trials were screened out from the preliminary 3126 records. All included studies were high-quality in methodology, except for Bilgen 2013 and Ruan 2015. Three-dimensional laparoscopy was superior to two-dimensional laparoscopy in terms of surgical time (P < 0.00001), blood loss (P = 0.01), perioperative complications (P = 0.04) and hospital stay (P = 0.03). Additionally, both techniques demonstrated comparable results of secondary endpoints, including drainage volume (P = 0.74), drainage time (P = 0.26), numbers of retrieved lymphnodes (P = 0.85), hospital expenses (P = 0.49), anastomosis time in prostatectomy (P=0.15) and 6-month continence rate (P = 0.61). The pooled outcomes of primary endopoints were verified to be stable by sensitivity analysis. Although Begg's test (P = 0.215) and Egger's test (P = 0.003) revealed that there was publication bias across included studies, Trim-and-Fill method confirmed that the results remained stable.
CONCLUSION
Three-dimensional laparoscopy is a preferably surgical option against two-dimensional laparoscopy due to its better surgical efficacy.

Review
OBJECTIVE
To perform a systematic review and meta-analysis of available prospective and retrospective studies comparing the minimally invasive (laparoscopic or robot-assisted) simple prostatectomy (MISP) and laser enucleation of the prostate for treating male lower urinary tract symptoms in high-volume prostates, as laser enucleation of the prostate is the new trend for treating high-volume prostates (>80 mL) but many urologists now prefer MISP.
METHODS
A systematic search was done using the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Cochrane databases in June 2019, with research terms including: 'laser', 'laparoscopy', 'enucleation', 'BPH', 'simple prostatectomy', 'Millins', and 'adenomectomy'. The meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
RESULTS
Of 38 screened articles, six were analysed and a total of 975 men were included. The average operative time, length of stay and catheterisation time were significantly shorter in the laser enucleation group ( = 0.006, < 0.001 and P < 0.001, respectively). The amount of prostatic tissue removed during surgery was comparable between both the laser enucleation and MISP groups ( = 0.39). The International Prostate Symptom Score, prostate-specific antigen level, maximum urinary flow rate and post-void residual urine volume were also comparable at 3 months. Finally, similar transfusion rates and Clavien-Dindo complication rates were observed ( = 0.08 and = 0.41, respectively).
CONCLUSION
This systematic review of the literature and meta-analysis provide a further demonstration of the safety and effectiveness of both laser enucleation and MISP. While laser enucleation had a shorter catheterisation time and hospital stay than MISP, the latter still had unique and specific indications.

Review
OBJECTIVE
The objective was to investigate the current evidence and discern urinary continence rates post robot-assisted laparoscopic radical prostatectomy (RALP).
METHODS
A systematic review of the literature was carried out, searching the Embase, Scopus and PubMed databases between 1 January 2000 and 1 May 2020. The search terms "Robotic prostatectomy AND continence" were employed. Articles were selected in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Statistical analysis was performed using the programme R; cumulative analysis of percentage of men continent was calculated.
RESULTS
A total of 3101 abstracts and 50 full text articles were assessed, with 22 publications included (n = 2813 patients). There were 21 randomised controlled trials and one partly randomised controlled trial with four publications comparing RALP to other prostate cancer treatments. Thirteen studies explored different RALP techniques, and five studies examined vesicourethral anastomosis (VUA). There were statistically significant improvements in early urinary continence rates in three studies analysing reconstructive techniques (83% vs 60%, p = 0.04; 26.5% vs 15.4%, p = 0.016; 77% vs 44.1%, p ≤ 0.001). Long-term continence rates were not significantly improved across all studies assessing reconstruction. One study comparing RALP vs laparoscopic radical prostatectomy (LRP) demonstrated a statistically significant improvement in continence at 3 months (80% vs 73.3%, p < 0.001); 6 months (83.3% vs 81.4%, p < 0.001); 12 months (95% vs 83.3%, p < 0.001) and 24 months (96.7% vs 85%, p < 0.001). Early continence was less favourable for RALP when compared to brachytherapy (BT) patients at 3 months (86% vs 98.7%, p < 0.05) and 6 months (90.5% vs 98.7%, p < 0.05).
CONCLUSION
Early continence rates were improved across numerous techniques in RALP. These results were not translated into significantly improved long-term outcomes. Continence rates following RALP were favourable compared to LRP, similar to ORP and less favourable compared to BT. Our findings suggest that post-RALP continence can be further improved with alterations in robotic technique.
