Management of simple renal cysts in children.

Simple renal cysts are uncommon in children and their presentation and management has changed with increasing use of ultrasound scans. The aim of this study was to review our experience and highlight some peculiarities in diagnosis and management of these cases. Eight cases were diagnosed and two symptomatic cases underwent aspiration under ultrasound guidance; one case recurred and required re-aspiration. Differentiation of simple renal cysts from other cystic lesions of the kidney, aspiration of symptomatic cysts and the importance of long-term follow-up are discussed.
