Renal hydatid disease: diagnosis and treatment.

Four children with renal echinococcal cyst and associated liver involvement were treated in our clinic in the last 10 years. The diagnoses were suspected by ultrasonography and computed tomography and confirmed by the operative investigation that followed. One nephrectomy, one heminephrectomy and two cystectomies were performed. All children had uneventful recovery and they have not presented any recurrence so far. The value of the diagnostic modalities and the principles of the operative management are discussed.
