title: Peripelvic cysts simulating hydronephrosis.
abstract: Peripelvic cysts can have a sonographic appearance that is similar to hydronephrosis. Two cases are described where the initial sonogram suggested the diagnosis of pelvicalyceal obstruction, and on subsequent intravenous urography the correct diagnosis of peripelvic cysts was made.
