Modified one-layer microsurgical vasovasostomy in vasectomized patients.

Bilateral vasovasostomies were performed in 7 previously vasectomized patients. The method employed was a modification of a one-layer anastomotic technique. There was no correlation between the presence of absence of sperm in the vas fluid, presence or absence of sperm granuloma, and site of vasectomy. No correlation was revealed between the presence or absence of sperm in the vas fluid and the duration of obstructive period. After vasovasostomy, sperm was observed in the ejaculate in 86% of the patients. Only one patient's partner became pregnant. However, the partner of one patient with short postoperative period and good seminal finding after vasovasostomy was expected to become pregnant. This modified method of one-layer microsurgical vasovasostomy can be performed more easily and quickly, but requires further clinical experience and evaluation of usefulness.
