Bilateral scrotal extra peritoneal herniation of ureters - Computed tomography urographic findings and review of the literature

Scrotal herniation of the ureter is an extremely rare and often misdiagnosed condition with possible serious surgical complications. Most reported cases occur in obese men during the fifth and sixth decades of life. Two types of ureteroinguinal hernias are defined: paraperitoneal (more frequent and acquired form with a peritoneal hernia sac in which other abdominal structures are found) and extraperitoneal (uncommon and congenital form without a peritoneal sac that is almost always composed of the ureter and fat tissue). A case of scrotal extraperitoneal ureteral hernia with exquisite computed tomography urographic and ultrasound findings is presented.
