Micturating Cystourethrogram: X-ray of the bladder

An MCUG is an X-ray examination of the bladder, urethra, and ureters. These structures are difficult to see on X-rays, so a contrast dye material is used to highlight these organs. The contrast is introduced into the bladder through a urinary catheter.

There is no preparation for the MCUG.

During the exam
During the exam, you will need to lie on the X-ray table. The contrast material will be in a bottle that is connected to the catheter. The contrast material will be dripped into the bladder slowly and the radiologist will be able to watch the bladder fill, with the fluoroscopy machine. When the bladder is full of the contrast material, the radiologist will take several X-rays and may ask you to move in different positions for these X-rays. The technologist will then remove the catheter and you will be encouraged to empty your bladder into a urinal. The radiologist will most likely be taking X-rays while you are emptying your bladder.

After the exam
You may resume normal eating and drinking. The contrast material is a colorless liquid that is excreted in the urine so you won’t notice it. There are no restrictions after the examination. The reports will be available on the next day or within 24 hrs.
