Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Thulium-fibre laser (TFL)
The laser used in this group for surgical procedure ureteroscopic lithotripsy will be the Olympus SOLTIVETM Premium SuperPulsed laser system with a 365micron laser fibre. The laser pulse setting will be 1J x 10Hz, short pulse duration (adjusted up to 600microseconds).
Ureteroscopic lithotripsy
Ureteroscopic lithotripsy is one of the surgical procedure options for ureteric stone less than 1.5 cm. While many energy systems has been used for stone fragmentation during ureteroscopy, laser energy is the most commonly used approach for stone fragmentation.
Holmium: yttrium-aluminum-garnet (Ho: YAG)
The laser used in this group for surgical procedure ureteroscopic lithotripsy will be the Lumenis VersaPulse® PowerSuiteTM 100W laser system with a 365micron laser fibre. The laser pulse setting will be 1J x 10Hz. Pulse duration is not adjustable in this machine (up to 600microseconds).
