Outcome and Safety of Thulium Fiber Laser for Urinary Stone Diseases - a Cross-sectional Study

Introduction: Thulium fiber laser (TFL) was introduced into the urological armamentarium as an alternative to Ho:YAG energy source. This study aims assess outcome and safety of RIRS using TFL in patients with proximal ureteric renal stone requiring intervention.
 Methods: It a hospital based cross-sectional conducted Department Urology Birat Medical College- Teaching Hospital over period 6 months (September 2022 February 2023) adults size upto 20mm. The procedure assessed for clearance, operative time, stay related complications.
 Results: We included initial 50 cases. Mean age, calculus size, volume density were 40.02± 13.97 years, 14.45±3.36mm, 534.46±209.53 mm3, 1046.96±236.88 HU respectively. Complete clearance achieved 92% (46 cases) 8% CSRF (4 cases). Procedure complications occurred 12% (8) cases.
 Conclusions: newer source is safe effective lithotripsy during acceptable complications.
