We compare the utilization of MOSES Technology with an industry standard holmium laser fiber during mini and ultra-mini access percutaneous nephrolithotomy (MPCNL). METHODS: This was a retrospective case series of MPCNL, defined as PCNL with renal access diameter from 11-20F. All surgical cases were performed at a single ambulatory surgical center by one of two endourologic specialists between July 2017 and July 2020. Patients underwent laser lithotripsy and stone extraction through a MPCNL access sheath. Lithotripsy was performed using either MOSES holmium laser fiber or an industry standard holmium laser fiber (the same respective fiber was used for every case in each arm). Patient and laser records were analyzed for laser performance with a primary endpoint of treatment efficiency score. Univariate statistics were performed using two tailed t-test and chi-squared test for continuous and categorical independent variables, respectively. Efficiency scores were calculated as the quotient of stone burden on preoperative CT scan by laser utilization time (mm3/s). RESULTS: One-hundred and forty patients met our study inclusion criteria. Seventy-nine patients underwent lithotripsy with a standard laser fiber and 62 patients underwent treatment with MOSES. There were no significant differences in patient age or comorbidity between the two cohorts. The primary location for most stones were lower pole, renal pelvis or proximal ureter for both cohorts. Mean stone volume was 20.5mm for patients who received MOSES and 18.5mm for patients treated with a standard fiber. The provider estimated post-procedure stone free rate was 95% for all patients. Procedures with MOSES Technology resulted in significantly reduced total operative times (85.9 min vs 98.1 min, p=0.03) and reduced intracorporeal treatment times (38.82 min vs 44 min, p=0.05). MOSES demonstrated improved treatment efficiency (2.4mm3/s vs 1.8mm3/s, p=0.03) compared with the standard fiber. There was no significant difference in estimated post-procedure stone-free rate or staged same laterality procedures. CONCLUSIONS: MOSES Technology demonstrates reduced operative times and intracorporeal operative time during MPCNL. In our series, MOSES Technology outperformed an industry standard holmium laser fiber in treatment efficiency with no significant differences in clinical outcomes Source of Funding: Lumenis Ltd © 2021 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 206Issue Supplement 3September 2021Page: e318-e318 Advertisement Copyright & Permissions© 2021 by American Urological Association Education and Research, Inc.MetricsAuthor Information Meagan Dunne More articles by this author Max Drescher More articles by this author Joel Abbott More articles by this author Julio Davalos More articles by this author Expand All Advertisement Loading ...
