Prospective Single-center Study Comparing Thulium Fiber Laser to Pulsed Thulium:YAG Laser in the Ureteroscopic Treatment of Nephrolithiasis
This research study is being conducted to assess the ability and efficiency of two laser systems to break up kidney stones during ureteroscopy with laser lithotripsy for kidney stone treatment.
• Solitary renal stone 7 to 20 mm in size or in the case of multiple stones the conglomerate diameter (additive maximal diameter of all stones on axial imaging of computed tomography) of 7-20 mm is required
• Must be a suitable operative candidate for flexible ureteroscopy per American Urological Association guidelines
• Must be able to give consent
• Bilateral ureteroscopy will be permitted but only the first side (per surgeon discretion) will be included in the study
• Surgeons participating in the study must be urological attending surgeons or fellows with subspecialty training in Endourology
