Year: 2026
Type: article
Study design: Observational Study
Abstract: PURPOSE: To investigate the safety and efficacy of mini-endoscopic combined intrarenal surgery (ECIRS) in older patients with renal and ureteral stones. METHODS: Consecutive patients with renal or ureteral stones who underwent mini-ECIRS were retrospectively analyzed at three Japanese tertiary care institutions between 2015 and 2021. Data on patient backgrounds, stone characteristics, and postoperative indications were collected and evaluated. After matching preoperative and intraoperative factors in older patients and other groups, postoperative factors were assessed using univariate analysis. RESULTS: The final analysis included data from 1303 single-session mini-ECIRS of 1432 cases collected. The patients were divided into two groups: those aged > 75 and those aged < 75 years, with 121 and 1182 patients. From each group, 112 cases matched for eight factors, performance status, body mass index, sex, hydronephrosis, percutaneous nephrostomy, pyuria, preoperative urinary tract infection, and preoperative ureteral stenting, were selected. The univariate analysis was performed on postoperative factors between the groups of matched older and matched non-older patients, and there was no significant difference in any factor, including postoperative hospitalization duration, complications, and stone-free rate (SFR). CONCLUSIONS: To the best of our knowledge, this multicenter cohort study is the first to compare the efficacy and safety of the mini-ECIRS between older patients and other groups. It was discovered that surgery could be performed with a similar quality even in patients aged 75 and older compared to that in other groups.
