Study Summary

The investigators aim to compare the performance of the Super Pulse Thulium fiber laser (SP TFL) with that of the standard Holmium: Yttrium-Aluminium-Garnet (Ho:YAG) laser. The investigators hypothesize that the electronically-modulated laser diodes, of the TFL offers the most comprehensive and flexible range of laser parameters among laser lithotripters leading to more efficient (4 times more) and effective stone dusting resulting in production of finer dust particles obviating the need for postoperative ureteric stenting which remains a major source of patient discomfort.
