What are the Risks?

The risks are low with this test. Some patients could get a urinary tract infection (about 3%) from the catheter. Also, the catheter could damage the urethra, bladder or nearby structures. It’s best to work with a highly experienced urologist.

A very small number of people have an allergic reaction to the contrast agent. It is rare because the agents are put into the urinary system, not the blood stream.
