[Diagnosis of kidney pelvis cancer].

The new imaging procedures should improve the preoperative assessment of patients with renal pelvis carcinoma. At the Department of Urology, University of Freiburg from 1976-1986 48 patients with renal pelvis carcinoma were treated. 92% of tumors (69% looked like renal pelvis carcinoma preoperatively, 23% like kidney tumors without histological determination) were detected preoperatively. Advanced tumor stages (T4N+M1) (21%) were diagnosed correctly in 7/10 cases preoperatively and have a poor prognosis.
