Duplicated vas deferens as an incidental finding during indirect inguinal hernia repair: A case report and literature review

Abstract

Duplication of vas deferens is an anomaly that is generally encountered during inguinal hernia repair, orchiopexy, radical prostatectomy, varicocelectomy, and vasectomy. The estimated rate of this anomaly in the United States is 0.01%. This anomaly may predispose to iatrogenic vas deferens injury during inguinal hernia repair. Embryological point of view suggests that the duplication of the mesonephric duct system could result in duplicated vas deferens. Failure to recognize this anomaly may lead to injury, obstruction, or spermatic granuloma. Furthermore, it is important to identify duplicated vas deferens during vasectomy to avoid failure of the procedure. Identification of duplicated vas deferens is important during inguinal hernia surgery, vasectomy, and varicocelectomy. Herein, we report a case of duplicated vas deferens during open indirect inguinal hernia repair.
