It is unknown whether patients who presented with symptomatic urolithiasis during the initial months of the COVID-19 pandemic suffered greater morbidity. Methods: We retrospectively reviewed ED presentations from a Philadelphia healthcare system for symptomatic urolithiasis betweenMarch-June 2020 and compared these with presentations for the same time period from the year prior. Patient demographics, stone characteristics, management and clinical outcomes were compared between the two years. Results: 139 patients presented during 2020 compared to 269 in 2019. There were fewer patients who presented during the initial COVID-19 pandemic surge who had obesity (37.41% vs. 49.44%, p=0.024), hyperlipidemia (18.71% vs. 31.60, p=0.006), and asthma (5.76% vs. 16.73%, p=0.002). Although overall stone characteristics did not differ between the two groups, a larger proportion of patients in 2020 presented with an obstructing stone (81.16% versus 64.1%, p=0.001). Patients who presented during the COVID-19 pandemic did not have higher rates of infection, acute kidney injury, or complications. Rates of surgical modalities, emergent procedures, and discharges from the ED were similar between the two years. Conclusions: The COVID-19 pandemic initial surge resulted in fewer ED presentations for symptomatic urolithiasis; however, patients who did present were more likely to have obstructing stones, perhaps due to delaying presentation to avoid COVID-19 exposure in the ED. Despite higher rates of obstruction, clinical outcomes and morbidity were similar. MP2-05 14
