Abstract

Aims To evaluate the effect of pre-RIRS ESWL on the efficiency and safety of RIRS in the treatment of proximal ureter stones. 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. Results There were 56 patients in Group-1 and 95 patients in Group-2. The demographic and clinical properties were similar between the groups. The stone-free rates, peroperative complications and postoperative complications were also similar between the groups; however, the fluoroscopy time was significantly higher in Group-1 (p=.043). The cut-off duration of 10 weeks between ESWL and RIRS had reasonable/favourable discriminating ability, with a 51% sensitivity and 88% specificity rate for stone-free status. Conclusion Performing ESWL on the proximal ureter stones before RIRS did not change the efficacy and safety of RIRS. The time between the patient’s last ESWL session and RIRS had a predictive value for stone-free status, but did not have any effect on complications.
