Lessons learned after the disruption caused by COVID-19 in the management of urolithiasis: An example of adaptation in a high-volume center.

BACKGROUND

The aim was to determine the impact of COVID-19 pandemic on urolithiasis presentation and management.

METHODS

In this retrospective study, we comparatively evaluated urgent and elective procedures due to urolithiasis during the early eight months of the COVID-19 pandemic (March 1, 2020, to October 31, 2020) compared to the same period a year before, and between waves. The student's t-test, chi-square test, Mann-Whitney U test and Fisher's exact test were used to compare the patients' characteristics and outcomes between the two periods and waves.

RESULTS

Five hundred and thirty procedures were included. The overall numbers of surgical procedures due to urolithiasis were similar between pre-pandemic and pandemic periods. Regarding elective surgery, our data draw attention to the increased complication rate in the pandemic times, but no statistically significant differences in terms of types of procedures and need for complementary treatments were observed. We noted that patterns of presentation of complicated renal colic were different during COVID-19 pandemic, with a higher number of days after the onset of symptoms and a higher proportion of patients presenting acute kidney injury. Furthermore, a significant increase of creatinine levels at presentation in first wave was detected, and a growth in the number of urgent procedures after the first wave was noted, owing to the delay in urolithiasis treatment and diagnosis.

CONCLUSION

The COVID-19 pandemic has negatively affected both urgent and elective management of urolithiasis. Lessons about the management of urolithiasis in this context should be learned to avoid fatal complications and improve standards of care.
