PURPOSE: We determined the incidence of @entity130 at a tertiary care university infertility center and the results of surgical repair. MATERIALS AND METHODS: Records of 472 @entity1 surgically explored for obstructive @entity3893 between 1984 to 1996 were reviewed. Enrollment criteria included history of inguinal, pelvic and scrotal (other than vasectomy) surgery. Conventional ipsilateral and crossover vasovasostomies and vasoepididymostomies were performed. Patency rate was defined as presence of complete sperm with tails in a postoperative semen analysis. Followup included a minimum of 2 semen analyses. Only naturally conceived pregnancies were included. RESULTS: Of 472 @entity1 34 (7.2%) had an @entity130 with a mean obstruction interval of 20.5 +/- 1.9 years. Mean @entity1 age was 36.7 +/- 1.8 years. @entity130 was secondary to bilateral @entity169 in 19 @entity1 , unilateral hernia repair in 11, renal transplantation in 2, appendectomy in 1 and spermatocelectomy in 1. @entity169 was the most common etiology of the @entity130 (20 @entity1 ), followed by adult @entity169 (10). A total of 36 microsurgical reconstructive procedures were performed, including 20 @entity717 . There were 26 @entity1 (29 procedures) available for followup (mean 21.0 +/- 3.7 months). Total patency rate per procedure was 65% and pregnancy rate was 39%. Patency and pregnancy rates per conventional ipsilateral procedures were 62.5 and 35.7% and per crossover procedures 64.2 and 42.8%, respectively. CONCLUSIONS: @entity169 is the most common cause of @entity130 . Results of treatment of @entity130 are somewhat lower than for @entity1 with obstructive @entity3893 due to vasectomy. Iatrogenic injuries are associated with longer vasal defects, impaired blood supply and longer obstructive intervals frequently resulting in @entity3892 . Crossover reconstruction is particularly useful when contralateral @entity194 is present. Intraoperatively aspirated sperm should be cryopreserved for later use in case the reconstruction fails.
