摘　　要：Although microsurgical vasoepididymostomy(MVE)is an effective treatment for epididymal obstructive azoospermia,some patients may experience delayed patency or suboptimal semen parameters after patency.However,research into patency time,semen quality postpatency,and associated influencing factors remains limited.This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique,with a follow-up period of over 12 months for 150 patients.The overall patency rate was 75.3%,with 86.0%of patients achieving patency within 6 months following MVE.Unexpectedly,factors such as age,history of epididymitis,duration of surgery,side of anastomosis,sperm motility in epididymal fluid,and the site of anastomosis showed no correlation with patency time.Nonetheless,our univariate and multivariate linear regression analysis indicated that only the site of anastomosis was positively correlated with and could independently predict postoperative total motile sperm count.Therefore,the site of anastomosis might serve as a predictor for optimal postoperative semen quality following the MVE procedure.
