Successful nephrectomy of isolated renal hydatid cyst associated with chronic pyelonephritis: A case report from...

Hydatid disease, primarily affecting liver and lungs, poses challenges with isolated renal cysts. A 29-year-old female with intermittent right flank pain and urinary burning was diagnosed with a Bosniak category 4 hydatid cyst (HC) after positive echinococcus antibodies. Imaging confirmed the diagnosis, leading to a three-month albendazole treatment followed by right nephrectomy and partial liver resection. Histopathological analysis confirmed HC and chronic pyelonephritis. The patient had an uneventful recovery and returned to normal activities. Hydatid cysts in the kidney are rare, often requiring surgical intervention for symptomatic cases. Accurate diagnosis and timely surgical intervention are crucial for effective management.
