However, their high cost poses a challenge, prompting consideration of reusing disposable instruments. This study aims to compare stone-free rates (SFR) and complications between reprocessed disposable ureteroscopes and new ones in a multicenter cohort.Methods: This prospective, observational, multicenter study included patients who underwent RIRS between May 2022 and May 2023 at three centers in Argentina. Patients were divided into two groups: Group 1 used a brand new disposable ureteroscope and Group 2 used a reprocessed disposable ureteroscope. Stone size, location, stone-free rate, postoperative complications, and subjective evaluations of deflection and vision were analyzed.Results: Seventy-seven patients were included: 21 in Group 1 and 56 in Group 2. The average stone size was 10.9 mm in Group 1 and 8.6 mm in Group 2 (P = 0.0188). Stone location in the renal pelvis was 42% in Group 1 and 25% in Group 2 (P = 0.406). SFR were 71.4% in Group 1 and 73.2% in Group 2 (P = 0.999). No differences were found regarding the subjective assessment of vision and deflection as evaluated by the surgeons. Postoperative urinary tract infections occurred in 9.5% of Group 1 and 16% of Group 2 (P = 0.717).Conclusions: Despite the larger stone size in Group 1, the stone-free rate and postoperative infection rates were similar between both groups. Reprocessing disposable instruments does not appear to affect the effectiveness or infection rate of RIRS.","PeriodicalId":47352,"journal":{"name":"Indian Journal of Urology","volume":"41 3","pages":"216-219"},"PeriodicalIF":0.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12312838/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144776488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to compare the therapeutic suitability of the thulium fiber laser (TFL) and the holmium laser (HL) in the treatment of entombed stents.Methods: In this benchtop study, first, the time taken for each laser to transect the stent was recorded in 10 experiments/laser. Next, the force required to break the stent following 5 s of laser contact was measured in 15 randomized experiments/laser. Finally, seven experiments of simulated ureteroscopy on entombed stents were performed per laser. Lasers were operated at 0.8 J, 12 Hz with 270 µm fibers, and 6 Fr stents were utilized. Endpoints included time to release the stent, laser energy, and stent damage.Results: The stent transection time was shorter with the TFL compared to the HL (22.02 vs. 61.46 s; P < 0.001). After 5 s, the TFL transected the stent with lesser force compared to the HL (5.34 vs. 15.24 N; P = 0.004). Both required lesser force to break the stent compared to the baseline (33.8 N; P < 0.001). On simulated lithotripsy, the lithotripsy time (12.7 vs. 8.5 min; P = 0.11) and laser energy (4.7 vs. 2.7 kJ; P = 0.09) were similar between the TFL and HL. The mean stent damage score was higher when using the TFL compared to the HL (36.9 vs. 15.7; P = 0.017).Conclusions: The TFL resulted in faster stent transection, reduced breakage force, and greater stent damage. Urologists should be cautious when releasing entombed stents using the TFL as the laser may significantly weaken the stent, increasing the risk of fracture during removal.","PeriodicalId":47352,"journal":{"name":"Indian Journal of Urology","volume":"41 3","pages":"205-209"},"PeriodicalIF":0.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12312839/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144776490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
