- Retrograde urethrogram
A retrograde urethrogram is a routine radiologic procedure used to image the integrity of the (typically male)
urethra . The procedure involves the injection of a radiopaque dye (contrast agent) into the urethral meatus of theglans penis in conjunction withx-ray imaging of thepelvic area. It is used when there is suspicion of urethral trauma, such as a history of trauma to the area followed by pain, inability to void urine, or the presence of blood at the urethral meatus.Leakage of the dye at any point between the
bladder and tip of the penis suggests urethral injury (usually secondary to pelvic trauma) and is an indication for surgical intervention.References:New England Journal of Medicine procedure videos: Male Urethral catheterization http://content.nejm.org/cgi/video/354/21/e22/
