Urethral catheterization is a common invasive procedure applied for several purposes on children. Voiding cystourethrogram (VCUG) is a diagnostic fluoroscopic procedure, which is commonly used in assessing urinary tract infections in children and which requires urethral catheterization. We report a case of intravesical catheter knotting, which is a rare complication of VCUG.
