Brief Summary

The study has been conducted in Urology department at Kafrelsheikh University Hospital between Feburary 2021 to December 2023. informed consent was taken from eligible patients and were randomized into three groups, Group A :Flexible ureteroscope (F-URS) group underwent holmium laser lithotripsy using flexible ureteroscopy (Boston® scientific (lithovue) while, Group B : extracorporeal shock wave lithotripsy (ESWL) group underwent electromagnetic extracorporeal shock wave lithotripsy (STORZ® MEDICAL Modulith SLX-F2 FD21, Germany) .Group C : Mini perc group underwent holmium laser lithotripsy using Karl® Storz MIP set.
