Super Pulsed Thulium Fiber Laser (sTFL) + Flexible Negative Pressure Ureteral Access Sheath (UAS) Intervention
The intervention combines a Super Pulsed Thulium Fiber Laser (sTFL) with a power setting of 0.8J and a frequency of 12 - 20Hz for stone fragmentation and a Flexible Negative Pressure Ureteral Access Sheath (UAS) that allows access to the stone site and enables negative pressure suction for stone removal.
Super Pulsed Thulium Fiber Laser (sTFL) + Conventional Ureteral Access Sheath (UAS) Intervention
The intervention combines a Super Pulsed Thulium Fiber Laser (sTFL) with a power setting of 0.8J and a frequency of 12 - 20Hz for stone fragmentation and a Conventional Ureteral Access Sheath (UAS) used for access to the upper ureter or ureteropelvic junction for stone treatment.
