Alternative names:

Biopsy - brush - urinary tract; Retrograde ureteral brush biopsy cytology

Definition:

a diagnostic procedure in which renal (kidney) or ureter tissue is removed for examination.

How the Test is Performed

Regional (spinal), or general anesthesia may be used. You are positioned and a cystoscope (a fiberoptic scope) is placed through your urethra into the bladder. A guide wire is inserted through the cystoscope and into your ureter.

The cystoscope is then removed, leaving the guidewire in place. A ureteroscope (small telescope to visualize the inside of the ureter and kidney) is passed over or beside the guide wire.

Once the suspect area is identified, a nylon or steel brush or biopsy forceps is placed through the ureteroscope and the lesion is rubbed with the brush or biopsied with the biopsy forceps. When the brush or biopsy forceps is removed, the tissue from the lesion is removed from the instrument.

How to Prepare for the Test

You must sign a consent form. Fasting for about 6 hours is recommended. You will be given a mild sedative before the test.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust.

How the Test will Feel

Your bladder may feel full, and there may be some cramping or discomfort during the test. The test will take about 30 to 60 minutes.

Afterward, there may be some mild cramping or discomfort. Some burning may occur the first few times you empty your bladder.

Why the Test is Performed

This test is used to obtain a specimen of kidney (renal pelvis or calyx) or ureter tissue when X-ray (or other test) shows a lesion in this area or when there are suspicious cells in the urine.
