Renal Pelvic Carcinoma

A series of 22 cases of renal pelvic carcinoma were reviewed in an attempt to find characteristics which would distinguish this entity from hypernephroma which it closely resembles. Distinctive angiographic characteristics are enlarged pelviureteric artery, fine neovascularity, vascular encasement, and absence of arteriovenous shunting. Since ureteronephrectomy is the preferred treatment for renal pelvic carcinoma, the importance of differentiating this tumor from other renal lesions is strongly stressed.
