A total of 624 of 699 vasovasostomy patients was followed during the last 20 years. Better results were obtained when there was shorter duration of obstruction, bilateral straight vas-to-straight was anastomosis and bilateral presence of sperm in the vas fluid during vasovasostomy. Results of end-to-end and side-to-side macrosurgical anastomosis, as well as of 1-layer and 2-layer microsurgical anastomosis were similar. Macrosurgical success rates were 84 per cent for patency and 35 per cent for pregnancy in the 300 cases. Microsurgical success rates were 90 per cent for patency and 51 per cent for pregnancy in 324 cases. Failure of patency was caused mainly by anastomotic scar formation with sperm and suture granulomas. Failure of pregnancy was owing mainly to inadequate postoperative semen quality.
在过去20年里，对699例输精管吻合术患者中的624例进行了随访。当梗阻时间较短、双侧输精管端端吻合以及输精管吻合术中双侧输精管液中存在精子时，效果更佳。端端和端侧宏观手术吻合以及单层和双层显微手术吻合的结果相似。300例宏观手术的通畅成功率为84%，妊娠成功率为35%。324例显微手术的通畅成功率为90%，妊娠成功率为51%。通畅失败主要是由吻合口瘢痕形成伴精子和缝线肉芽肿引起的。妊娠失败主要是由于术后精液质量不佳。
