What is a RGU with MCU?

RGU with MCU is a combined contrast-enhanced X-ray examination of the urethra and urinary bladder. It helps evaluate urethral strictures, urethral injuries, bladder abnormalities, vesicoureteral reflux, urinary obstruction, and other lower urinary tract disorders.

FAQs

What is RGU with MCU?

RGU with MCU is a combined contrast-enhanced X-ray examination of the urethra and urinary bladder. It combines a Retrograde Urethrogram (RGU) and a Micturating Cystourethrogram (MCU) to provide a comprehensive evaluation of the lower urinary tract.

Why is RGU with MCU performed?

This examination is commonly performed to evaluate urethral strictures, urethral injuries, recurrent urinary tract infections (UTIs), vesicoureteral reflux (VUR), bladder outlet obstruction, urinary incontinence, congenital urinary tract abnormalities, and other lower urinary tract disorders.

What is the difference between RGU and MCU?

RGU evaluates the urethra by injecting contrast through the urethral opening to detect narrowing or injury. MCU evaluates the urinary bladder and urine flow by filling the bladder with contrast through a catheter and taking X-ray images while the bladder fills and during urination.

Which structures are examined during the test?

The examination evaluates the urethra, urinary bladder, bladder neck, and the flow of urine during urination. It also helps detect vesicoureteral reflux, where urine flows backward toward the kidneys.

Can RGU with MCU detect urethral strictures?

Yes. It is one of the most reliable imaging examinations for detecting urethral strictures, including their location, length, and severity, helping guide appropriate treatment.

Can children undergo RGU with MCU?

Yes. This examination is commonly performed in children to investigate recurrent urinary tract infections, vesicoureteral reflux, and congenital urinary tract abnormalities when clinically indicated.
