Diagnosis of Urethral Injuries
Retrograde urethrography In men, the diagnosis of a urethral injury is usually confirmed by retrograde urethrography, an x-ray taken after a radiopaque contrast agent, a liquid that is visible on x-rays, is put directly into the end of the urethra. Retrograde urethrography is done before a catheter is passed through the urethra into the bladder. In women, a flexible endoscope is used to examine the lining of the bladder and the urethra ( Cystoscopy ).
