Pelviscrotal vasovasostomy: refining and troubleshooting

Abstract

Purpose: Obstruction of the vas deferens in the inguinal canal may occur as a sequel of inguinal surgery. The condition is occurs in 26.7% of cases following childhood herniotomy. Open surgery in the inguinal region for anastomosing the remnants of the vas is difficult and associated with high morbidity. We have previously reported an alternative based on anastomosing the pelvic vas deferens (harvested laparoscopically) to the scrotal vas deferens and bypassing the inguinal vas. This technique, termed Shaeer pelviscrotal vasovasostomy, is easier to perform with much less morbidity. In this study we present the results of performing the procedure bilaterally at the same session as well as technique troubleshooting.

Materials and methods: A total of 25 patients with azoospermia due to inguinal obstruction of the vas deferens underwent unilateral (15) or bilateral (10) surgery. Patients were followed for 1 year.

Results: Of the 25 patients 17 (68%) had a sperm concentration of between 11.88 and 17 million per ml. Some patients who remained azoospermic underwent reoperation and the obstacles to a successful anastomosis were analyzed and resolved.

Conclusions: Shaeer vasovasostomy is a practical approach to inguinal obstruction of the vas deferens. It enables a reliable anastomosis, simultaneous bilateral repair and lower morbidity in terms of wound healing and hernia as well as a shorter convalescence.
