title: Renal cyst puncture and abscess formation.
abstract: Percutaneous needle puncture and aspiration of suspected cystic renal masses may provide accurate diagnosis in selected cases. However, renal cyst puncture is not a totally innocuous procedure and certain complications may be encountered. Report is made of 2 cases of renal cyst puncture followed by abscess formation, necessitating surgical intervention. An improved technique involving surgical preparation of the operative area and utilization of double-needle method of cyst puncture is advocated.
