Multiple unusual urological locations of hydatic cysts including kidney, retrovesical and spermatic cord. A new case report.

Human hydatidosis is endemic in regions with temperate climate where pastoral farming is common. It is frequent in the southern shore of the Mediterranean, particularly in the Maghreb countries. It remains asymptomatic for long period, and the diagnosis is often delayed. The most affected organs are the liver and lungs. Hydatic disease of the urinary tract is an unusual entity. Our case concerns multiple unusual locations of hydatic disease in the urinary tract, including renal, retrovesical and spermatic cord, associated with splenic and intraperitoneal locations. Coexistence of hydatic cysts in such locations of urinary tract has not been previously reported.
