Abstract
Hydatidosis is an endemic, widely distributed anthropozoonosis that involves the liver, lungs, and other organs. We report two cases of large renal hydatid cysts. Diagnosis was suspected based on radiological examinations. The patients were given albendazole tablets 400 mg twice per day (one month before and one month after surgery), with monitoring of blood count and liver enzymes. During follow-up assessment for renal hydatid cysts, the possibility of recurrence must be kept in mind. These cysts can completely destroy the kidney.
