The chance of refertilization in patients with obstructive azoospermia increases using microsurgical operation techniques. For the establishment of the therapeutic concept the excluding or confirming diagnosis of a distal obstruction of the spermatic canal by means of the preoperative vasovesiculography is necessary. In 19 patients with an obstruction in the transitional zone of epididymus and spermatic duct after epididymovasostomy the patency of the spermatic canals was achieved in 56% of the cases and a conception rate of 22%.
采用显微外科手术技术可提高梗阻性无精子症患者再次受精的几率。为确立治疗理念，术前通过输精管造影术排除或确诊精索管远端梗阻是必要的。在19例附睾输精管吻合术后附睾与精索管过渡区梗阻的患者中，56%的病例实现了精索管通畅，受孕率为22%。
