[An organ-preserving operation in primary ureteral cancer].

The authors report on a recidivation-free case of a ureter carcinoma operated by resection of the ureter and following plastics after Boari. The necessity of the revision of the nephro-ureterectomy which at present is already generally valid in the treatment of this disease is explained. The authors are of the opinion that the operation preserving the organ agrees with the principles of the carcinoma surgery also in cases of a tumour of the ureter.
