Treatment of bilateral renal pelvic and ureteral tumors. A review of 45 cases.

Abstract

A particular type of kidney disease, the so-called Balkan nephropathy, is to be observed in some areas in Yugoslavia. This type of disease is very often associated with ureteral and pelvic tumors. 495 cases were observed (308 of pelvic and 187 of ureteral origin). Taking into consideration the frequency of bilaterality (9%) as well as of renal insufficiency (50%), we have been forced to preserve the kidney in tumoral cases instead of performing radical nephrectomy. The results on 45 bilateral pelvic and ureteral tumors are presented in this paper.
