Summary
HO:YAG Laser urethrotomy effectively treated short segment urethral stricture in 90% of patients. This minimally invasive procedure offers a safe and simple therapeutic option for urethral stricture management.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Urethral stricture is a common urological condition.
- Traditional treatments for urethral stricture can have limitations.
Purpose of the Study:
- To evaluate the effectiveness of Holmium: YAG (HO:YAG) Laser urethrotomy for treating short segment anterior urethral stricture.
- To assess the safety and outcomes of this novel therapeutic approach.
Main Methods:
- A prospective cross-sectional study involving 30 male patients with short segment anterior urethral stricture (>2cm).
- Treatment administered using a LISA 80 Watt Holmium Laser machine with energy settings of 0.8 to 1.5 joules.
- Postoperative follow-up included uroflowmetry and retrograde/voiding cystourethrogram at 3-month intervals for 6 to 12 months.
Main Results:
- 90% of patients (27 out of 30) demonstrated good urine flow (Qave>16.0 ml/sec) and adequate urethral caliber on retrograde urethrogram.
- Recurrence was observed in 10% of patients (3 out of 30), managed with optical internal urethrotomy and clean intermittent self-catheterization.
- Satisfactory short-term outcomes were achieved in 90% of cases.
Conclusions:
- HO:YAG Laser urethrotomy is a highly effective treatment for short segment urethral stricture.
- The procedure is simple, safe, and represents a favorable new therapeutic option.
- Long-term follow-up is recommended for definitive conclusions.
