[Transurethral thulium laser urethrotomy for urethral stricture]

Area of Science:

• Urology
• Minimally Invasive Surgery
• Laser Technology

Background:

• Urethral stricture and atresia pose significant challenges in urological practice.
• Minimally invasive treatments are sought to improve patient outcomes and reduce morbidity.

Purpose of the Study:

• To evaluate the efficacy and safety of endourethrotomy using a thulium laser for treating urethral stricture.
• To assess the clinical outcomes and complications associated with this minimally invasive approach.

Main Methods:

• Thirty-six patients with urethral stricture or atresia underwent endourethrotomy with thulium laser.
• The procedure involved vaporization and excision of scar tissue to restore urethral continuity.
• Clinical effects and complications were systematically observed.

Main Results:

• The mean operative time was 35 minutes. Smooth urination was achieved within 2-6 weeks post-catheter removal.
• During a mean follow-up of 12 months, 73% (27/36) of patients required no reintervention.
• Recurrence or complications were managed successfully in most cases, with only one patient needing open urethroplasty.

Conclusions:

• Thulium laser endourethrotomy is a safe and effective minimally invasive option for short urethral strictures.
• The technique is also suitable for severe urethral stricture and urethral atresia, demonstrating satisfactory short-term outcomes.
