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.).
