What is a RGU+MCU?

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

FAQs

What is RGU + MCU?

RGU + MCU is a combined contrast-enhanced X-ray examination of the urethra and urinary bladder. It includes a Retrograde Urethrogram (RGU) and a Micturating Cystourethrogram (MCU) to evaluate the lower urinary tract.

Why is RGU + MCU performed?

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

What is the difference between RGU and MCU?

In RGU, contrast dye is injected into the urethra to evaluate its structure and detect narrowing or injury. In MCU, the bladder is filled with contrast material through a urinary catheter, and X-ray images are taken while the bladder fills and during urination to assess bladder function and urine flow.

Which structures are examined during the test?

The examination evaluates the urethra, urinary bladder, bladder neck, and the passage of urine during urination. It also helps assess whether urine flows backward toward the kidneys (vesicoureteral reflux).

Can RGU + MCU detect urethral strictures?

Yes. It is one of the most effective imaging examinations for detecting urethral narrowing (strictures), determining their location, length, and severity.

Can RGU + MCU detect bladder injuries or abnormalities?

Yes. The examination can identify bladder abnormalities, bladder outlet obstruction, leakage of urine, diverticula, and congenital urinary tract abnormalities.
