[Postrenal amuria in polycystic degeneration of a residual kidney (author's transl)].

A case of a residual kidney and polycystic renal degeneration is reported in which postrenal anuria developed from a cluster of cysts filling the entire renal pelvis. The anuria was repired by removing the intrapelvic cysts and creating a temporary renal fistula. A sudden onset of anuria and the corresponding symptoms (e.g., acute abdominal pain) and also the familiar progressive polycystic degeneration of the kidney should arouse suspicion of an obstruction caused by cysts.
