Summary

The authors hypothesize that the RIRS using 150-microm Tm-fiber laser is superior than fiber with larger diameters, as 200-microm Tm-fiber laser or 200-microm holmium fiber laser, in such points as follows:

* decreasing surgery time and laser-on time due to possibility of 4.3 fold ablation efficacy increase, which has been shown by Andreeva et al.;
* increasing the flexible ureteroscope tip deflection lower pole stones availability;
* decreased risk of complications and a better irrigation and visualization due to better irrigation with smaller fiber;
* increasing of lithotripsy efficacy and laser beam density by lowering of beam focal spot due to using of lesser fiber diameter
