Recurrent Bulbar Urethral Stricture After Straddle Injury and Failed Endoscopic Treatment
A 34-year-old man was struck in the perineum by a bicycle frame 2 years ago. He developed voiding difficulty and was treated with repeated urethral dilations and one internal urethrotomy, but symptoms recurred. He now has a suprapubic catheter placed 3 weeks ago for acute retention. Retrograde urethrogram shows a 2.5-cm bulbar stricture with no urethral lumen opacification proximal to it; a suprapubic cystogram shows a normal bladder and no vesicoureteral reflux. Urine culture grows Pseudomonas aeruginosa. He is otherwise healthy and works as a driver. He asks for “another laser” because he cannot take time off for a big operation. He has no history of lichen sclerosus or radiotherapy.
1. How would you evaluate the stricture and counsel him about repeated endoscopic treatment versus urethroplasty?
Read the worked answer
A 2.5-cm bulbar stricture after trauma, with failure of repeated dilation and internal urethrotomy, is a recurrent stricture with a low expected success rate from further endoscopic treatment. The retrograde urethrogram shows no proximal lumen opacification, so I would obtain a voiding cystourethrogram through the suprapubic tube to define the proximal extent and stricture length before planning reconstruction. I would also assess for infection, lichen sclerosus, and any prior hypospadias surgery, because these change the repair.
I would counsel him that urethroplasty offers the best durable success for a 2.5-cm bulbar stricture, whereas another laser or dilation is likely to fail and may worsen the stricture. I would explain the trade-off honestly: urethroplasty requires longer recovery and possibly a graft, but repeated endoscopic procedures also consume time, carry anesthesia risk, and do not address the scar. His occupation as a driver matters for recovery planning, but it is not a reason to choose an operation with a high failure rate.
2. What is the role of urine culture and suprapubic tube before urethroplasty, and how would you time surgery?
Read the worked answer
The suprapubic tube is valuable because it diverts urine and allows the urethra to rest, but it can become colonized. A Pseudomonas aeruginosa urinary tract infection should be treated with culture-directed antibiotics before reconstruction, and I would repeat a urine culture after treatment to confirm clearance. I would not operate through actively infected urine because of the risk of wound infection, graft loss, and recurrent stricture.
Timing should allow the infection to resolve and the tissues to stabilize, usually several weeks after adequate treatment. I would optimize nutrition, stop smoking if applicable, and plan the approach based on stricture length and proximal extent. Preoperative imaging with retrograde urethrogram and voiding cystourethrogram through the suprapubic tube is essential. If the bladder is small or there is significant inflammation, I would delay further. The suprapubic tube can be maintained until the repair is healed and a voiding trial is appropriate.
3. If he insists on avoiding urethroplasty, what would you tell him about expected outcomes and the conditions for another endoscopic attempt?
Read the worked answer
I would tell him that another endoscopic treatment is a temporizing option, not a cure. For a 2.5-cm recurrent bulbar stricture after failed dilation and urethrotomy, durable success is substantially lower than with urethroplasty, and he should expect a meaningful chance of recurrence and further procedures. I would not offer another endoscopic attempt if the stricture is obliterative or if the proximal urethra cannot be defined, because the risk of injury and worsening scarring is high.
If he still chooses endoscopy, I would require that the stricture be short and non-obliterative, that infection be cleared, and that he accept close follow-up with voiding symptoms, uroflowmetry, and imaging if recurrence is suspected. I would document informed consent, including the possibility of conversion to urethroplasty or suprapubic diversion. The goal is to respect his preference without overstating the likely benefit.
