Popis:	This study aimed to evaluate the efficacy and safety of vasal vessel-sparing modified single-armed 2-suture longitudinal intussusception vasoepididymostomy (SA-LIVE) to epididymal obstructive azoospermia patients. Forty consecutive epididymal obstructive azoospermia cases, who underwent microsurgical vasoepididymostomy in Shanghai General Hospital from January 2019 to October 2019, were included in this study. Twenty cases underwent SA-LIVE (group A), and 20 cases underwent vasal vessel-sparing SA-LIVE (group B). Until March 2021, the mean follow-up period was 16.9 ± 4.1 (12-23) months. The overall patency rate was 82.5%, and 80% and 85% for group A and group B respectively. The mean time to achieve patency was 4.11 ± 2.74 months. The overall natural pregnancy rate was 51.5%(17/33) at the mean follow-up of 16.9 months. The natural pregnancy rate was 50.0% for group A and 52.9% for group B (p > .05). At the time of 6 months post-operation, the patency rate was 70% for group A and 80% for group B (p = .465); the natural pregnancy rate was 0% for group A and 31.3% for group B (p = .022). Vasal vessel-sparing SA-LIVE is safe and effective to achieve favourable patency and pregnancy rates. Preserving vasal vessel would improve natural pregnancy rate at a very early stage.
