e describes the preliminary experience of a new method by Thulium laser for failed ureteral stenotic treatment.
Materials and Methods:
Between 2012 and 2014, a total of 9 patients of failed previous treatment for ureteral stenosis were managed by Thulium Laser endoureterotomy. An 8-10 watts Thulium laser power was used to incise open the stenotic ureter by 300-microm fiber through ureteroscopy. Double J catheter of 8 Fr. were used for post-incisional stenting. The mean follow-up time was 8.4 months. Successful treatment was defined as no obstructive uropathy on an imaging study, being free of associated symptoms, at follow-up period.
Successful treatment was observed in 6 patients (66.7%). Three patients (33.3%) had recurrent ureteral stricture, receiving long-term double J stenting. No procedural-related complications have been noted.
In our limited experience, Thulium laser ureterotomy is a safe and feasible method for ureteral stenosis with failed previous treatment.
