Laparoscopic correction of transverse testicular ectopia with persistent Müllerian duct syndrome

An 11-month old male patient visited our hospital with swelling of the right inguinal area. The right testis was palpable in the right scrotum while left testis was not in the left scrotum. During laparoscopic exploration, the left testis was found around the right inguinal area, with the left spermatic cord across the pelvic cavity from left side. When the left testis was pulled, a tubular structure, Müllerian duct remnant, and the right spermatic cord came into the abdominal cavity. The Müllerian duct seemed like a uterus was located between both vas deferens. We divided it because the length of the bilateral vas deferens was not sufficient for orchiopexy. After laparoscopic right orchiopexy and left trans-scrotal approach orchiopexy, bilateral inguinal herniorrhaphy was performed laparoscopically.
