Micturating Cysto Uretherogram (MCU)

An MCU or Micturating Cysto Uretherogram is a x-ray examination that is used to demonstrate the renal system. The examination uses x-ray contrast to demonstrate the position, function and movements of the bladder, ureters and kidneys.  An MCU can be used in the investigation and ongoing management of a variety of conditions. As this is a dynamic study it can be used to show function as well as anatomical structures. You need to ask your doctor why you need a MCU.
