What's known on the subject? and What does the study add? Objective: The aim of this study is to compare the efficacy and complications of holmium laser and pneumatic lithotripsy used in the ureterorenoscopic treatment of proximal ureteral stones. Materials and Methods: Data of 638 patients, who underwent ureterorenoscopy (URS) due to proximal ureteral stones in different centers, were obtained from patient files. The patients were divided into two groups according to the type of lithotripter used: group 1; laser lithotripter (n=324; 50.8%) and group 2; pneumatic lithotripter (n=314; 49.2%). URS was considered successful upon determination stone-free status with the imaging methods after treatment. The effectiveness and the complications of holmium:yttrium-aluminum-garnet laser and pneumatic lithotripsy were compared. Results: The total success rate of URS was 82.6% and the complication rate was 8.1%. The mean age of patients was similar between the groups; however, the body mass index values, stone surface area and stone Hounsfield unit were significantly higher in group 1. Although the mean operative time, complication rate and the mean length of hospital stay were similar between the groups; the URS success and postoperative ureteral Turkiye is an endemic region for urinary system stone disease and the incidence rate is 14.8%. Currently, ureterorenoscopy, where laser and pneumatic energy sources are used as lithotripter, is the first choice in the treatment of ureteral stones. The aim of this multi-centered study was to compare the efficacy of holmium laser and pneumatic lithotripters used in the ureterorenoscopic treatment of proximal ureteral stones and investigate their complications.
