A voiding cystourethrogram (VCUG) is prescribed for a child. What education should be provided to the parents?
Explanation & Rationale
Choice A reason: A VCUG does not determine whether an infection has resolved. The resolution of infection is typically assessed using urinalysis and urine culture after completing antibiotic therapy. Therefore, this statement is inaccurate and provides false reassurance. Choice B reason: VCUG is not used to detect kidney stones. The proper diagnostic tools for stones include renal ultrasound, non-contrast CT, or intravenous pyelogram. VCUG is focused on imaging the lower urinary tract, specifically assessing urine flow and bladder emptying function. Choice C reason: The VCUG is a diagnostic procedure, not a preventive one. It helps identify structural or functional abnormalities such as vesicoureteral reflux but does not directly prevent infection or its complications. Preventive measures would include antibiotic prophylaxis and good perineal hygiene practices. Choice D reason: The VCUG (voiding cystourethrogram) is a fluoroscopic imaging test that evaluates the bladder and urethra while the bladder fills and empties. Its main purpose is to detect vesicoureteral reflux (VUR), a condition in which urine flows backward from the bladder into the ureters or kidneys. Identifying VUR is important because it can predispose children to recurrent urinary tract infections and kidney damage. Hence, this is the correct answer.
