Methods
The patients in the study population were divided into 2 groups. Group-1
was composed of patients who had undergone ESWL for proximal ureter
stones before RIRS, and Group-2 was composed of patients who directly
underwent RIRS without any prior ESWL. The clinical and demographic
properties of the patients were analysed in the RIRSearch database. The
operative outcomes, peroperative complications, postoperative
complications, hospitalization time and the stone-free rates were
compared between the groups.
