Learn about Transitional Cell Cancer of the Renal Pelvis and Ureter

Transitional cell cancer of the renal pelvis and ureter is a disease in which malignant (cancer) cells form in the renal pelvis and ureter.

The renal pelvis is the top part of the ureter. The ureter is a long tube that connects the kidney to the bladder. There are two kidneys, one on each side of the backbone, above the waist. The kidneys of an adult are about 5 inches long and 3 inches wide and are shaped like a kidney bean. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine collects in the middle of each kidney in the renal pelvis. Urine passes from the renal pelvis through the ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body.

The renal pelvis and ureters are lined with transitional cells. These cells can change shape and stretch without breaking apart. Transitional cell cancer starts in these cells.

Transitional cell cancer can form in the renal pelvis, the ureter, or both.

Renal cell cancer is a more common type of kidney cancer. See the PDQ summary about Renal Cell Cancer Treatment for more information.

A personal history of bladder cancer and smoking can affect the risk of transitional cell cancer of the renal pelvis and ureter.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for transitional cell cancer of the renal pelvis and ureter include the following:

  • Having a personal history of bladder cancer.
  • Smoking cigarettes.
  • Taking a lot of certain pain medicines, such as phenacetin.
  • Being exposed to certain dyes and chemicals used in making leather goods, textiles, plastics, and rubber.

Signs and symptoms of transitional cell cancer of the renal pelvis and ureter include blood in the urine and back pain.

These and other signs and symptoms may be caused by transitional cell cancer of the renal pelvis and ureter or by other conditions. There may be no signs or symptoms in the early stages. Signs and symptoms may appear as the tumor grows. Check with your doctor if you have any of the following:

  • Blood in the urine.
  • A pain in the back that doesn't go away.
  • Extreme tiredness.
  • Weight loss with no known reason.
  • Painful or frequent urination.

Tests that examine the abdomen and kidneys are used to detect (find) and diagnose transitional cell cancer of the renal pelvis and ureter.

The following tests and procedures may be used:

  • Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
  • Urinalysis: A test to check the color of urine and its contents, such as sugar, protein, blood, and bacteria.
  • Ureteroscopy: A procedure to look inside the ureter and renal pelvis to check for abnormal areas. A ureteroscope is a thin, tube-like instrument with a light and a lens for viewing. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. A tool may be inserted through the ureteroscope to take tissue samples to be checked under a microscope for signs of disease.
  • Urine cytology: A laboratory test in which a sample of urine is checked under a microscope for abnormal cells. Cancer in the kidney, bladder, or ureter may shed cancer cells into the urine.
  • CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
  • Ultrasound: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. An ultrasound of the abdomen may be done to help diagnose cancer of the renal pelvis and ureter.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the pelvis. This procedure is also called nuclear magnetic resonance imaging (NMRI).
  • Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. This may be done during a ureteroscopy or surgery.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) depends on the stage and grade of the tumor.

The treatment options depend on the following:

  • The stage and grade of the tumor.
  • Where the tumor is.
  • Whether the patient's other kidney is healthy.
  • Whether the cancer has recurred.

Most transitional cell cancer of the renal pelvis and ureter can be cured if found early.
