Persistent mesonephric duct found at laparoscopy for impalpable testis.
Laparoscopy is an increasingly popular choice for treatment of the impalpable testis. There are many anatomical variants that may be found at operation. We present a case of a 1-year-old boy who presented with an impalpable right testis and absent right kidney, and at laparoscopy was found to have a persistent mesonephric duct. Awareness of this variation allowed for adequate excision and subsequent investigations.
