Multicystic nephroma masquerading as hydatid cyst: a diagnostic challenge.

Background: Multicystic nephroma is an uncommon, non-familial renal neoplasm that is usually benign. About 200 cases of this lesion have been described in the literature.

Case Presentation: We report on a Sudanese child who presented at the age of two and a half years with an abdominal mass, clinical and radiological features favored the diagnosis of hydatid cyst which is endemic in this African tropical country, and the diagnosis of multicystic nephroma was only possible after histopathological examination.

Current status of retrograde intrarenal surgery for management of nephrolithiasis in children.

Purpose: To review the current status of retrograde intrarenal surgery (RIRS) for renal stones in children focusing on its indications, outcomes and success in the management of nephrolithiasis.

Materials And Methods: Between 1988 and 2009, a comprehensive PubMed/MEDLINE literature review on RIRS was conducted.

Results: The available literature is limited and heterogeneous, skewed by favorable results on ureteral stone outcomes.
