Interventional urethral balloon dilatation before endoscopic visual internal urethrotomy for post-traumatic bulbous urethral stricture: A case report

Figure 1 Retrograde urethrography of a 12-year-old boy with straddle injury. Retrograde urethrography performed in the emergency room after a straddle injury confirms partial rupture of the bulbous urethra (arrow).

Figure 2 Interventional urethral balloon dilatation. A: Severe stricture of the bulbous urethra (white arrow) is identified using antegrade urethrography with injection of contrast agent using a suprapubic catheter. B: After the guide wire is successfully navigated to reach the entrance of the bladder neck, a 6-mm balloon catheter is advanced over the guide wire and laid across the site of the urethral stricture (black arrow).
