title: Renal cystography: unusual complication.
abstract: A patient is  described in whom renal cyst aspiration and subsequent contrast material instillation caused pain, flank mass and spiking temperature, evantually necessitating exploration and drainage of a sterile abscess. Undiluted, hyperosmotic contrast material was the probable cause of this complication. A simple, easy way to calculate cyst volume and amount of contrast material to be used during cyst aspiration injection studies is discussed.
