Ureteral retrograde brush biopsy cytology

Alternative names:

biopsy - brush - urinary tract; retrograde ureteral brush biopsy cytology

What the risks are:

• allergy to contrast agent (iodine based) - consult the health care provider if there are allergies to sea food, as these may cause allergic reactions to the contrast agent.
• allergy to anesthetic
• bleeding, hemorrhage
• infection (urinary tract infection, pyelonephritis, or sepsis)
• perforation (hole) of the ureter

Special considerations:

This test should not be performed in people with acute urinary tract infection or obstruction at or below the biopsy site.

After the test, watch for abdominal pain, flank pain, or blood in the urine (a small amount of pink color is normal the 1st time or 2 that you urinate, but grossly bloody urine or bleeding that lasts longer than 3 times urinating is significant). Report these or any other new symptoms to the health care provider.
