Abstract

Penoscrotal transposition (PST) is a rare congenital anomaly characterized by caudal location of the penis with respect to the scrotum. PST may be seen in isolation or associated with caudal regression syndrome. We present a case of an infant born with penoscrotal transposition, bladder agenesis, a solitary dysplastic kidney, and caudal regression. The patient developed anuria and was referred for angiography for preoperative planning for renal transplantation and genital reconstruction. Angiography demonstrated an aberrant abdominal umbilical artery, an anomaly classically associated with sirenomelia but also has been described in caudal regression.
