In urology, a voiding cystourethrogram (VCUG), also micturating cystourethrogram (MCUG), is a technique for watching a person's urethra and urinary bladder while the person urinates (voids). The technique consists of catheterizing the person in order to fill the bladder with a radiocontrast agent, typically cystografin. Under fluoroscopy (real time x-rays) the radiologist watches the contrast enter the bladder and looks at the anatomy of the patient. If the contrast moves into the ureters and back into the kidneys, the radiologist makes the diagnosis of vesicoureteral reflux, and gives the degree of severity a score. The exam ends when the person voids while the radiologist is watching under fluoroscopy. Consumption of fluid promotes excretion of contrast media after the procedure. It is important to watch the contrast during voiding, because this is when the bladder has the most pressure, and it is most likely this is when reflux will occur.

Vesicoureteral reflux (kidney reflux) is diagnosed with an ultrasound and VCUG. Children who have recurrent urinary tract infections are given this test to determine the risk of subsequent infections causing potentially damaging kidney infections.

Indications[edit]

All males with recurrent UTIs or abnormality on ultrasound if first UTI urinary tract infections
Females < 3 years of age with their first UTI.
Females < 5 years of age with febrile UTIs
Older females with pyelonephritis or recurrent UTIs
Suspected obstruction (e.g. bilateral hydronephrosis)
Suspected bladder trauma or rupture
Stress incontinence (urine)

Contraindications[edit]

Untreated urinary tract infection
Hypersensitivity to contrast media
Fever within the past 24 hours

PURPOSE: Vesicoureteral reflux is frequently diagnosed in the pediatric population. Endoscopic treatment has become a popular form of first-line therapy. Available products offer good short-term success rates. However, the cost of these injected implants is an issue. We evaluated the success of endo
