title: [Differential diagnosis of postoperative fistulas of the urinary tract (author's transl)].
abstract: A case is demonstrated in which an indwelling intravenous catheter was pushed by mistake via V. subclavia and the right heart into the V. cava inf. There the catheter perforated the wall of the V. cava. The continued infusion induced a cystic retroperitoneal tumor. The puncture of this tumor was followed by a fistula that was misinterpreted as a fistula of the urinary tract.
