Results
In this present study, the files of 1081 patients were reviewed. 57 of these patients were excluded from the study due to their CT did not contain any pulmonary images. After the criteria were applied 1024 patients were included in this study. The mean age of patients 44.3 ± 14.9 years (3-101 years). 357 (34.9%) of the patients were female, and 667 (65.1%) were male.
We observed that 99 (9.7%) of these patients had findings related to missed diagnosed COVID-19 pneumonia on the lung base images of abdominal CT. Although 885 (86.4%) of patients had no pathological pulmonary findings, 40 (3.9) patients had other pathological pulmonary findings (non-related COVID-19) (such as atelectasis, pulmonary fibrosis, pleural effusion, etc.) (Figure 3).
The mean age of patients who had findings COVID-19 were 56.4 ± 14.7 years (22-92 years). 35 (35.4%) of these 99 patients were female, 64 (64.6%) were male; these findings were similar to the patients without abnormal pulmonary imaging (Chi-Square; p: 0.930). Also, there were no abnormal urinary system findings on abdominal CT imaging 39 of these 99 patients. These patients had only pulmonary findings related to COVID-19 (Figure 4).
We observed that 688 (67.2%) of these patients had abnormal urinary system findings (such as ureteral stones, renal stones, renal cell carcinoma, simple renal cyst, etc.). There were 288 patients with ureteral stones, 261 patients with renal calculi, 44 patients with simple renal cyst, 8 patients with angiomyolipoma, and 86 patients with other urinary tract pathologies (renal malignancies, hydronephrosis, ureteropelvic junction obstruction, etc.).
