Review Meta Analysis
Outcome of varicocele repair in men with nonobstructive azoospermia: systematic review and meta-analysis.
The objective of this systemic review was to evaluate the benefit of repairing clinical varicocele in infertile men with nonobstructive azoospermia (NOA). The surgically obtained sperm retrieval rate (SRR) and pregnancy rates following assisted reproductive technology (ART) with the use of retrieved testicular sperm were the primary outcomes. The secondary outcomes included the presence of viable sperm in postoperative ejaculate to avoid the testicular sperm retrieval and pregnancy rates (both assisted and unassisted) using postoperative ejaculated sperm. ⋯ In addition, approximately 44% of the treated men will have enough sperm in the ejaculate to avoid sperm retrieval. Limited data on pregnancy outcomes with both postoperative ejaculated sperm and harvested testicular sperm preclude any firm conclusion with regard to the possible increased fertility potential in treated individuals. In conclusion, the results of our study indicate that infertile men with NOA and clinical varicocele benefit from varicocelectomy. Given the low/moderate quality of evidence available, it is advisable that doctors discuss with their patients with NOA the risks and benefits of varicocele repair.

Review Meta Analysis
Efficacy and safety of local anaesthetics for premature ejaculation: a systematic review and meta-analysis.
To assess the efficacy and safety of local anaesthetics for premature ejaculation (PE), a systematic review of the literature was performed using the Cochrane Library, PUBMED and EMBASE. We screened and retrieved the randomized controlled trials on the treatment of PE with local anaesthetics. End points included intravaginal ejaculation latency time (IELT), patient-reported outcome assessments and adverse events. ⋯ A higher rate of adverse events occurred compared with placebos (odds ratio: 3.30, 95% CI: 1.71-6.36), but these events were restricted to local side effects. In addition, significantly greater improvement was observed in patient-reported outcomes. In summary, local anaesthetics can prolong IELT and improve ejaculatory control and sexual satisfaction.

Review Meta Analysis Comparative Study
The results of transperineal versus transrectal prostate biopsy: a systematic review and meta-analysis.
This systematic review was performed to compare the efficacy and complications of transperineal (TP) vs. transrectal (TR) prostate biopsy. A systematic research of PUBMED, EMBASE and the Cochrane Library was performed to identify all clinical controlled trials on prostate cancer (PCa) detection rate and complications achieved by TP and TR biopsies. Prostate biopsies included sextant, extensive and saturation biopsy procedures. ⋯ Although the data on complications were not pooled for the meta-analysis, no significant difference was found when comparing TR and TP studies. TR and TP biopsies were equivalent in terms of efficiency and related complications. TP prostate biopsy should be an available and alternative procedure for use by urologists.
