A micturating cystourethrogram (MCUG) is one type of imaging test – a test that uses special equipment to create one or more pictures of part of the inside of the body. This test may also be called a voiding cystourethrogram (VCUG).
A MCUG is a special type of X-ray test that looks inside your baby’s or child’s body while he or she is passing urine (weeing). Both ‘micturating and ‘voiding’ mean passing urine.A machine directs a series of X-rays into your child’s body over a period of time while his or her bladder empties. These are recorded as several images (pictures), using computerised digital equipment.
The MCUG can check whether the flow of urine fromyour child’s bladder is being blocked, or whether it goes up the wrong way. It can help diagnose some conditions, including vesicoureteral reflux and posterior urethralvalves.
