Whitaker Test

Also known as: urodynamic study.

What is a Whitaker test?

The Whitaker test is a medical test that can measure the amount of pressure present in the bladder or kidneys. It helps to diagnose if any obstructions or blockages exist in these parts of the body.

What happens during the procedure?

The patient is placed under general anesthesia, and a catheter is inserted into the bladder. Next, local anesthetic is used while a needle is inserted into the kidneys. The needle is used to inject contrast dye into the kidneys at a slow, steady rate. Then both the needle in the kidney and the catheter in the bladder obtain pressure measurements as the contrast dye flows through the kidney and bladder.

Is any special preparation needed?

No special preparation is needed for the test.

What are the risk factors?

Pain, discomfort and an allergic reaction to the contrast dye are all potential risk factors of the Whitaker test.
