We 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. We hypothesize that the electronically-modulated laser diodes, of the TFL offers the most comprehensive and flexible range of laser parameters among laser lithotripters [1]. 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.
