Acute urinary retention due to cystic echinococcosis: A case report

Urinary hydatidosis is very rare and represents 2% to 4% of all cases of cystic echinococcosis. We present a case of a 21-year-old man with symptoms of frequency, urinary retention and reduced force in urinary stream due to cystic echinococcosis. Anti-Echinococcus granulosus antibodies were determined by echinococcosis western blotting, and pelvic computed tomography revealed a 11 x 14 x 10-cm retrovesical homogeneous cystic mass. The patient underwent surgical intervention; the cystic mass and retrovesical cavity were removed. After a 3-year follow-up period, there was no episode of lower urinary tract symptoms. This case illustrates that cystic echinococcosis should be considered in every case of cystic mass, especially in endemic countries, such as Turkey.
