The aim is To look at the adequacy of the norm and higher recurrence regimens for superpulsed thulium fiber laser (SP TFL) retrograde intrarenal medical procedure (RIRS). An imminent investigation of patients with renal calculi of 10–30 mm was performed. For RIRS, we utilized the SP TFL (NTO IRE-Polus, Russia) and a 9.5F adaptable ureteroscope with 270° redirection and 3.6F working channel. Retropulsion and perceivability were surveyed dependent on the specialist’s criticism utilizing three-point Likert scales. The sans stone rate was surveyed at 3 months with CT. An aggregate of 40 patients were remembered for the examination with a mean age of 56 years, mean stone thickness of 880 ± 381 HU, mean stone size of 16.5 ± 6.8 mm, and middle stone volume of 883 (interquartile range 606–1664) mm3. Both removal adequacy and speed were higher in the 200-Hz mode (2.7 J/mm3vs 3.8 J/mm3 and 5.5 mm3/second versus 8.0 mm3/second, individually); besides, the higher recurrence connected with sped up (r = −0.21, p = 0.019). In any case, both expanded energy and recurrence didn’t prompt increment of laser-on schedule or intraoperative inconvenience rates.

SP TFL can viably crumble stones during RIRS with negligible entanglement rates. The utilization of higher recurrence regimens showed higher adequacy and removal speed and was not related with expanded intricacy rates.
