urethrogram การใช้

• If a urethral injury is suspected, a retrograde urethrogram should be performed before attempting to place a Foley catheter into the bladder.
• Specifically, when a retrograde urethrogram demonstrates extension of contrast from the proximal bulbous urethra into the perineum, there is an increase of grading of the injury from a Type 2 to a Type 3 classification.
