One prior study showed no difference in fluoroscopy time between the two modalities. Over time, techniques to reduce fluoroscopy during URS have evolved. The purpose of this study was to compare the outcomes and fluoroscopy times between URS and SWL for renal stones in modern practice. METHODS: Outcomes were retrospectively collected from 364 patients who underwent URS and 444 patients who underwent SWL for urolithiasis targeted using fluoroscopy in a single academic institution from July 2012 to February 2019. Patients with ureteral stones, renal stones <5 mm and >20 mm, and those who underwent both URS and SWL were excluded. After patient matching, 86 URS and 237 SWL patients were included for analysis. Mann-Whitney U and Chi-square tests were used to compare fluoroscopy time and clinical outcomes with p<0.05 considered significant. RESULTS: Gender distribution, age, BMI, stone size, and stone location were not different between patients. Total mean number of stones was higher in the URS group (2.4±1.4) compared to SWL group (1.5±0.9, p<0.05). Fluoroscopy time was greater in patients who underwent SWL (189.3±98.5 seconds) compared to those undergoing URS (6.7±11.9 seconds; p<0.05). Ureteroscopy had a significantly higher SFR compared to SWL (p<0.05). Both groups had similar complication rates (4.7 vs. 7.0%, p=0.32) and Clavien-Dindo scores. CONCLUSIONS: Our study demonstrates that in the modern era, SWL results in ∼27x increased radiation exposure compared to URS. In addition, this study agrees with prior findings demonstrating that URS has a higher stone free rate with a similar complication rate compared to SWL. This highlights the importance of developing strategies for reducing fluoroscopy time while performing SWL such as the use of ultrasound guidance.
