This document provides information about a voiding cystourethrogram procedure. It describes how the procedure is performed, including inserting a Foley catheter into the bladder and injecting contrast. Serial x-rays are taken of a full bladder, during voiding, and after voiding to assess for structural issues in the bladder and urethra like reflux or obstruction. The procedure evaluates causes of incontinence, urinary tract infections, and injuries. Risks include infection, reaction to contrast, and perforation of the bladder.
