Purpose: The novel coronavirus disease 2019 (COVID-19) has spread all over the world. The diagnosis of COVID-19 in asymptomatic patients and patients with non-respiratory symptoms remains a big concern. In this study, we aimed to evaluate the incidence of missed diagnosed COVID-19 pneumonia on abdominal computed tomography (CT) performed in patients admitted to our urology outpatient clinic. Methods: We reviewed the files of patients who were admitted to the urology outpatient clinic from 1 April to 1 November retrospectively. We included the patients who performed abdominal CT at the urology outpatient clinic for any reason and recorded demographic data and abdominal CT findings. We excluded patients with pulmonary symptoms and previously diagnosed with COVID-19. Also, patients without abdominal CT were excluded. We evaluated the rates of missed diagnosed COVID-19 pneumonia detection on the lung base images of abdominal CT. Results: 1024 patients were included in this study. We observed that 99 (9.7%) of these patients had findings related to COVID-19 pneumonia on the lung base images of abdominal CT. Although 885 (86.4%) patients had no pathological pulmonary findings, 40 (3.9%) patients had other pathological pulmonary findings. Conclusion: COVID-19 disease has become a pandemic all over the world. All healthcare professionals, including urologists, play an active role in the diagnosis and treatment of this disease. So, it should be kept in mind that COVID-19 pneumonia should be evaluated in patients admitted to the urology outpatient clinic with renal colic or abdominal pain.
