Cystography

Bladder scan

Risks are the same as for x-rays (radiation) and catheterization of the bladder.

There is a small amount of radiation exposure with any nuclear scan (it comes from the radioisotope, not the scanner). The radiation is very mild, and virtually all radiation is gone in a short time. However, any radiation exposure is discouraged for women who are or might be pregnant.

Risks for catheterization include a risk for causing a urinary tract infection and the risk (rare) of damage to the urethra, bladder, or other nearby structures.

This test is very useful to provide information about how the bladder responds to pressure, without exposure to radiographic contrast materials.
