Ureteral retrograde brush biopsy
What is Ureteral Retrograde Brush Biopsy?
A ureteral retrograde brush biopsy is a procedure that involves inserting a small brush into the ureter and collecting a tissue sample for examination. It is commonly performed in the diagnosis and treatment of urinary tract infections, kidney stones, and other kidney diseases. The procedure is also known as retrograde endourology.
Preparation for Ureteral Retrograde Brush Biopsy
Before the procedure, the doctor will review your medical history and may order additional tests. You may be asked to stop taking medications that can affect blood clotting such as aspirin, heparin, warfarin, and ibuprofen. If you are pregnant or lactating, the doctor may only perform the procedure if it is absolutely necessary.
Your doctor may also ask you to drink plenty of fluids for 24 hours prior to the procedure as this will help flush your kidneys and make the procedure easier. You will be asked to avoid eating or drinking anything 8 hours before the procedure.
Procedure for Ureteral Retrograde Brush Biopsy
During the procedure, you will be asked to lie on your back. The doctor will use an ultrasound to locate the ureter and then insert a small tube called a ureteroscope into the opening. The scope is equipped with a video camera and television screen to help guide the doctor.
Once the scope is in place, the doctor will insert the brush through the ureteroscope into the ureter. The brush collects a sample of the tissue lining the ureter. The sample is then examined to diagnose any urinary tract disease or infection.
Once the sample has been collected, the ureteroscope is then carefully withdrawn. The procedure usually takes about 30 minutes.
Types of Ureteral Retrograde Brush Biopsy
There are two types of ureteral retrograde brush biopsy:
- Flexible retrograde brush biopsy – This procedure is performed with a thin, flexible scope that is inserted into the ureter via the urethra.
- Rigid retrograde brush biopsy – This procedure uses a rigid scope that is inserted through a small incision in the abdomen.
Risks of Ureteral Retrograde Brush Biopsy
