title: Transitional cell carcinoma of renal pelvis.
abstract: Sixty-eight patients with transitional cell carcinoma of the renal pelvis were studied with respect to clinical presentation, tumor grade, stage and location, subsequent development of other urothelial tumors, and patient survival. Of the 66 patients with adjacent mucosa available for evaluation, 63 (95 per cent) had abnormal findings with severe dysplasia and CIS common in the high-grade, high-stage tumors. Twenty-eight patients (41 per cent) had transitional cell carcinoma previously, concomitantly, and/or subsequently, and in 14 patients (21 per cent) subsequent bladder tumors developed. Because of the relatively high tumor recurrence rate in the ureter (16 per cent) in patients who underwent subtotal ureterectomies, nephrectomy and complete ureterectomy including a bladder cuff should be the operation of choice in patients with carcinoma of the renal pelvis.
