Renal pelvis and ureter cancer

[Kit]

Cancers may cause blood in the urine or crampy pain in the side.
Diagnosis is usually by computed tomography.
Treatment is removal of the kidney and ureter.

Cancer can occur in the cells lining the central collecting area of the kidney (the renal pelvis—usually a type called transitional cell carcinoma of the renal pelvis) and in the slender tubes that carry urine from the kidney to the bladder (ureters). Cancers of the renal pelvis and ureter are much less common than cancers of the rest of the kidney or bladder. They probably occur in fewer than 6,000 people in the United States each year.
