Summary
For urethral stricture treatment, leaving a urethral catheter post-surgery is more effective than suprapubic cystostomy. This method shows fewer recurrences and better long-term outcomes for patients undergoing visual internal urethrotomy.
Area of Science:
- Urology
- Surgical Procedures
- Medical Device Technology
Background:
- Visual internal urethrotomy is a common treatment for urethral strictures.
- Optimal postoperative management, specifically catheterization duration, remains debated.
Purpose of the Study:
- To compare the efficacy of prolonged urethral catheterization versus suprapubic cystostomy after visual internal urethrotomy.
- To evaluate long-term outcomes and recurrence rates based on postoperative management.
Main Methods:
- Prospective randomized study comparing urethral catheterization and suprapubic cystostomy for 5 weeks.
- Follow-up ranged from 12-36 months (mean 25 months).
- Urethral flow rate and recurrence rates were assessed.
Main Results:
- Urethral catheterization showed significantly better results, with 13/20 patients recurrence-free versus 4/17 in the cystostomy group.
- 48% of patients (37/76) treated with postoperative urethral catheterization had normal or subnormal flow rates at 12-60 months.
- Younger patients and those with first-time strictures had better outcomes.
Conclusions:
- Prolonged urethral catheterization (5 weeks) is superior to suprapubic cystostomy for visual internal urethrotomy outcomes.
- Patient factors like age and prior treatment history influence success rates.
- Urethral diameter ratio is a useful measure of stricture severity.
