A cystourethrogram is a test that shows the urinary bladder. Commonly ordered by your physician to look for reflux of urine from the bladder back into the ureters, this test may also be done for urinary tract infections or other abnormalities. To do this test, a small catheter is placed into your bladder through the urethra. Once this catheter is in place, we will fill your bladder with x-ray contrast dye and take pictures using fluoroscopic imaging.
You should tell your technologist about any recent illnesses or other medical conditions, as well as any allergies you might have to medications. Women should always inform SSR staff if there is any possibility that they are pregnant.
A technologist positions the patient on their back on the fluoroscopy table. The genital area is cleansed and a small catheter is inserted through the urethra into the bladder. Sometimes a balloon is inflated to hold the catheter in place.
An iodine based contrast is instilled through the catheter to fill the bladder completely. Several x-ray images are then taken.
The catheter is then removed and the patient is asked to empty their bladder into a special urinal. This enables the radiologist to take pictures while the bladder is emptying.
The patient may feel discomfort or stinging as the catheter is inserted into the urethra and again when it is removed. The rest of the procedure is typically painless and takes approximately 45 minutes.
