[The late results following conservative surgery in transitional cell pyelocaliceal and ureteral carcinomas]

The paper reports on the tardy results following conservative surgeries performed in 15 cases of transitional supravesical carcinomas (8 pyelocaliceal and 7 ureteral). In cases the surgery was necessary (patients with tumours developed on the conservative operation was made deliberately. a unique kidney, in uremia, infiltrative, highly anaplastic), and in 8 patients. Two years after the surgery, 80% of the patients were alive, after 3 years, 66%, after 4 years, 47%, and after 5 years, 33%. The conservative surgeries in the transitional pyelocaliceal carcinomas have deliberate indications for small, unique lesions, T0-T1 N0 M0 G1, technically easily accessible. For the ureteral tumours, the conservative surgeries may be extended to T3 lesions, but with N0 M0, observing the oncologic limits of exeresis in length, that permit the reconstruction of the urinary tract by a rational surgery.
