A retrograde urethrography[1] is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra.

There are several relative contraindications such as: allergy to contrast agents, acute urinary tract infection, and recent instrumentation of urethra.

Warming the contrast medium before infusion into the urethra can help to reduce the chance of getting spasm of external urethral sphincter.

The catheter is gently pulled to straighten the penis over the leg of the same side to prevent the overlapping of any pathology in the posterior urethrae.

[4] If a urethral injury is suspected, a retrograde urethrography should be performed before attempting to place a Foley catheter into the bladder.
