Renal Pelvic and Ureteral Cancers
Key Points
Risk of renal pelvis and ureteral cancers increases with smoking, phenacetin orcyclophosphamideuse, chronic irritation, or exposure to certain chemicals. Do ultrasonography or CT with contrast if urinary tract symptoms are unexplained. Confirm the diagnosis histologically. Excise or ablate tumors, usually using radical nephroureterectomy, and monitor patients with periodic cystoscopy.
