[Conservative surgery of renal pelvic tumors].

In a large series of renal pelvic and ureteral tumors in Belgrade (Jugoslavia), 26 cases of renal pelvic tumors were operated with conservation of the kidney. The indications must be strictly observed, the possibility of a relapse being maximally excluded. The results, under strict indications, are quite well: from 26 operated cases the 12 from 16 followed longer that 5 years are alive and with good kidney function plus 1 with lost kidney. So the 74% success for 5 or more years completely justifies the conservation of the kidney. In other cases the nephroureterectomy must be practised. The author did in 188 cases.
