How did COVID-19 affect acute urolithiasis? An inner Anatolian experience

BACKGROUND: The COVID-19 pandemic has changed the number of patients seeking medical help from the emergency service (ES) with non-COVID complaints, consequencing in postponed presentations of different surgical and medical situations. Acute urinary stone disease is one of these situations and needs to be investigated in terms of the effect of COVID-19 on its presentation to the ES. METHODS: In this observational, retrospective, and single-center study, we scanned each abdominopelvic computed tomography requested in ES for possible acute urolithiasis during 1 year before and after the outbreak of COVID-19. We searched to state the number of abdominopelvic computed tomographies applied and the number of ratifying urinary stone positivity. We enrolled patients’ gender, age, stone location, and stone size. We also recorded C-reactive protein, leukocyte count, and creatinine and noted how long the patients suffering from pain, the duration until the intervention, and the management option selected for each case. RESULTS: Total number of abdominopelvic computed tomographies performed was 1089. Of these, 517 were pre-pandemic and 572 were peri-pandemic. The number of pre and peri-pandemic stone-positive scans were, respectively, 363 (70.2%) and 379 (66.2%) (P=0.643). The females’ percentage in the COVID-19 period (37.2%) was significantly lower than in the pre-pandemic period (54.3%) (P=0.013). The median size of ureter stones of the pre and peri-pandemic groups were, respectively, 4.8 mm and 3.9 mm depicting no significant difference (P=0.197). No significant difference was sighted between the pre and peri-pandemic groups concerning stone locations, blood parameters, painful duration, treatment options, and time to intervention. CONCLUSION: The COVID-19 pandemic resulted in neither sicker nor fewer patients suffering from acute ureteric colic in the ES.
