In a hospital setting, MCU refers to a specific x-ray test. Let's break down what that means.
An MCU is an x-ray test of the bladder as it fills and empties. This procedure is done to check if urine is flowing backward from the bladder up toward the kidneys, which is not how it should normally flow. This backflow is called reflux.
Why is an MCU performed?
An MCU is performed to evaluate the function of the bladder and urethra, and to detect vesicoureteral reflux (VUR).
What does an MCU check for?
Here's what an MCU looks for:
- Vesicoureteral Reflux (VUR): This is the primary reason for the test. VUR means that urine flows backward from the bladder into the ureters and potentially the kidneys.
- Bladder abnormalities: The test can also show the size and shape of the bladder.
- Urethral abnormalities: It can show any blockages or structural problems in the urethra.
Understanding the Process
The procedure generally involves inserting a catheter into the bladder. A contrast dye is then introduced, allowing the bladder and urinary tract to be visible on X-rays. X-rays are taken as the bladder fills and as the patient urinates.
