[Mucous adenocarcinoma of the urinary bladder (urachal carcinoma) (author's transl)].

A report is presented of 5 cases of urachal carcinomas (3 women and 2 men). The mucous adenocarcinomas were located on the apex of the urinary bladder. In 3 cases partial cystectomy and in 2 cases a subtotal cystectomy were performed. Two patients were treated with cytostatics postoperatively. The prognosis of urachal carcinomas is poor. 3 patients had metastases to the bones, cerebrum and peritoneum. Diagnostic and therapeutic procedures are discussed.
