The pandemic acute respiratory syndrome coronavirus 2 (SARS-CoV-2), named COVID-19 [1] , is generating a severe health emergency all over the world but particularly in some countries. The healthcare challenge is to provide assistance to the increasing number of infected patients, to contain ways of transmission and at the same time to treat all the non-deferrable medical conditions that continue to affect the population. Moreover, the most relevant problems are in the management of all first aid accesses and emergencies other than COVID-19. In this brief communication, we report our experience on the diagnostic and therapeutic procedures requested and performed for urinary stone emergencies during a 6-week period activity in a hospital partially converted to COVID-19 care and in the highest national level of COVID-19 infection (March-April 2020), with the management performed in the same hospital in a no-COVID-19 period (March-April 2019) 1 year ago. In particular, we analyzed differences between these two timerelated populations in terms of patients and urinary stone characteristics, symptoms and complications at presentation, diagnostic and therapeutic approaches, time of hospitalization. ANOVA analysis and Chi square test were used to quantify the differences between the two time periods. Some relevant data are obtained (Table 1) : (1) independent to COVID-19 infection, in our hospital, the number of first aid accesses for urinary stone emergencies did not significantly change (44 cases in the no COVID-19 period versus 36 cases in the COVID-19 period) (2) patients presenting during COVID-19 time showed significantly higher serum levels of creatinine (p = 0.026) when compared to a no-COVID-19 period. These data may suggest a delay in terms of patient presentation to the hospital, related to the pandemic. (3) However, no significant differences were detected in terms of complication rates, urinary stone diameter or grade of hydronephrosis due to COVID-19 pandemic. (4) Stone position significantly changed with a higher rate of lumbar ureter and lower of juxta-vesical site during COVID-19 period (p = 0.036). The reduction of first aid access for juxta-vesical site stones may be interpreted through a higher rate of its management using medical therapies at home. (5) Diagnostic and therapeutic approach to urinary stone emergencies did not significantly change compared to the non-pandemic period. In particular, the use of nephrostomy or ureteral stent for the first aid did not significantly change. Across a 6-week period during the peak of the COVID-19 pandemic, urinary stone emergencies continued to be managed with few significant variations in a geographical area at medium density for COVID-19 and in a hospital partially converted in first aid cares. An effective reorganization of health care facilities in hospitals can consent to do not reduce cares and resources for patients with other urgent and emergent conditions such as urinary stones [2] [3] . The findings presented here suggest that urinary stone emergencies are mainly severe, their care need to be continued and they were not significantly influenced by this pandemic.
