Summary
Endoscopic ureteral incision using the holmium laser effectively treated benign ureteral strictures, ureteropelvic junction obstruction, and ureteroenteroanastomotic strictures with a high success rate.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Laser Technology
Background:
- Benign ureteral strictures, ureteropelvic junction obstruction, and ureteroenteroanastomotic strictures pose significant clinical challenges.
- Traditional treatments can be invasive and associated with complications.
Purpose of the Study:
- To evaluate the efficacy and outcomes of endoscopic ureteral incision using the holmium laser for various ureteral strictures.
- To assess the safety and feasibility of this minimally invasive approach.
Main Methods:
- A total of 17 ureters in 15 patients underwent endoscopic ureteral incision with a holmium laser.
- Procedures were performed using semirigid or flexible ureteroscopes without prior balloon dilatation.
- A double-J catheter was placed post-incision for 6 weeks, followed by imaging surveillance.
Main Results:
- The mean operative time was 65 minutes.
- Complete stricture resolution was achieved in 86.7% of cases.
- Average follow-up was 20.5 months, demonstrating sustained efficacy.
Conclusions:
- Holmium laser endoscopic ureteral incision is a safe and effective treatment for benign ureteral strictures.
- The procedure offers a less invasive alternative with favorable outcomes.
- This technique is recommended as an initial treatment option.
