[Angiography of carcinomas of the renal pelvis (author's transl)].

The angiographic criteria of 19 renal pelvic carcinomas were analysed. Two groups of signs, direct and indirect, could be detected. Of 19 histologically proved cases of renal pelvic carcinomas, the diagnosis had not been made angiographically in the case of a small tumor, which was 11 mm in diameter. The usefulness of preoperative angiography for diagnosis and operative planning is emphasized.
