2. VOIDING
CYSTOURETHROGRAPHY

3. WHAT IS A VCUG?
 Radiologic investigation underfluoroscopy to
evaluate;
 **VU reflux
 *Bladder disease
 *Urethral stenosis, others

4. WHEN TO DO?
 UTI--- clinical febrile UTI+UA+ urine C/S
 ** Children <5 years;
 * U/S + VCUG
 * Renal U/S (2-3 days after infection)-- 
abnormal -- VCUG +/-IVP (4-6 wks after
acute infection) -----abnormal --  antibiotic
prophylaxis & refer to specialist

6. HOW TO DO?
 Patient preparation
 KUB scout film
 Insertion of foley catheter
 Introduced water soluble CM
 Serial film—fullbladder, during urinate, post
void

7. RADIATION DOSE
 For a child 5-10 years, effective radiation
dose is 1.6 mSv= nature background 6
months.
 Infant, effective radiation dose is 0.8 mSv=
nature background 3 months.

8. COMPLICATION
 Perforated urinary bladder
 Intrarenal infection
 Anaphylactoid reaction

10. NORMAL VCUG

11. NORMAL MALE VCUG

12. VU REFLUX

13. POSTERIOR URETHRAL
VALVE

14. IMAGING TECHNIQUE FOR
DETECTION OF
VESICOURETERAL REFLUX
 Direct Radionuclide Voiding Cystography
(DRVC)
 Voiding Cystourethrography ( VCUG)
 Voiding Urosonography ( VUS)
