Septic and febrile kidney stone presentations during the COVID-19 pandemic

Abstract

Introduction: During the early stages of the COVID-19 pandemic, hospitals shifted their resources and focus toward COVID-19 care and non-deferrable conditions. Renal colic is one of the most common urologic presentations to the emergency department (ED). In our study, we examined whether there was an increase in septic/febrile stone presentations to the ED requiring ureteral stent insertion after the public health restrictions during the COVID-19 pandemic. Methods: We carried out a retrospective cohort study and reviewed charts of septic/febrile stone patients requiring ureteral stent insertion from January 1, 2019, to March 16, 2020 (pre-COVID) and July 1, 2020, to December 31, 2021 (intra-COVID) at the QEII, Halifax, NS. The incidence of septic/febrile stone presentation, baseline characteristics, and perioperative outcomes were captured. Results: There were 54 patients in the pre-COVID group and 74 patients in the intra-COVID group. There were no statistically significant differences found in baseline or stone characteristics between the two groups (p>0.05). Patients in the intra-COVID group were found to have a longer presentation to operating room time when compared to the pre-COVID cohort (U=961.00, p=0.04). The intra-COVID group had 20 more cases of septic stone presentations compared to the pre-COVID group at the 15-month mark (pre-COVID, n=54; intra-COVID, n=74). Conclusions: We found increased time to operative intervention in the intra-COVID cohort compared to the pre-COVID cohort. The overall number of urgent and/or critically ill ureteric stone patients increased between cohorts but was not statistically significant.
