This study comprises a systematic review and meta-analysis of micmsurgical vasoepididymostomy outcomes in epididymal obstructive azoospermia.A comprehensive literature search was performed using Medline,Embase,and the Cochrane library that included all studies related to microsurgical *** included “vasoepididymostomy,”“epididymovasostomy,”“epididymal obstruction,”and “epididymis obstruction.”Event rate and risk ratio (RR)were *** rate and pregnancy rate were *** analysis comprised 1422 articles,including 42 observational studies with 2298 enrolled patients performed from November 1978 to January *** overall mean patency rate was 64.1%(95%confidence interval [CI]:58.5%-69.3%;F=83.0%),and the overall mean pregnancy rate was 31.1%(95%CI:26.9%-35.7%;I^2=73.0%).We performed a meta-analysis comparing the patency rate of bilateral microsurgical vasoepididymostomy and unilateral microsurgical vasoepididymostomy and found an RR of 1.38%(95%CI: 1.21%-1.57%;P <0.00001).A comparison of the site of microsurgical vasoepididymostomy showed that caudal or corpus area was favorable for patency rate (RR =1.17%;95%CI: 1.01%-1.35%;P =0.04).Patients with motile sperm in epididymal fluid exhibited an RR of 1.53%(95%CI:1.11%-2.13%;P =0.01)with respect to patency rate. Microsurgical vasoepididymostomy is an effective treatment for epididymal obstructive azoospermia that can improve male fertility. We find that performing microsurgical vasoepididymostomy bilaterally,anastomosing a larger caudal area,and containing motile sperm in epididymis fluid can potentially achieve a superior patency rate.
