영문 초록

Patients who visit the emergency room with urinary stones have difficulty lying down in a supine position due to severe pain when performing the KUB test. The purpose of this study was to find methods to reduce the patients pain and image distortion, and obtain medical images with high diagnostic values. After checking the standard classification of disease and cause of death, the target group consisted of 121 patients who had clearly distinguished stones from computed tomography. Patients with stones in the ureteralvesical junction were excluded. Qualitative image evaluation was performed by confirming the location of the stone in the computed tomography images. and evaluated the rate of visual discrimination of stones possible through KUB and abdominal plain X-ray. Quantitative image evaluation was performed on the KUB, abdominal plain X-ray images. The transverse process of the first lumbar vertebrae served as the standard point, and the length from this point to the lower part of the stone was measured. Results from looking at the rate of visual discrimination of stones possible through KUB and abdominal plain X-ray showed: 94 patients (77.6%) for KUB images and 91 patients (75.2%) for computed tomography images. The standard deviation for KUB and abdominal X-ray was 3 (2.4%). Comparing and analyzing the location from KUB images and abdominal plain X-ray images, the stone position was 10.1 mm in the kidney, 10.5 mm in the ureteropelvic junction, and 9.7 mm in the ureters. It was shown that the stone moved 10 mm on average with significant statistical difference (P<0.05). In cases where the pain is so severe that it is impossible to perform the test in the supine position, an alternative may be to check the stone position by performing a modified KUB test by having the patient stand in a vertical position. In the future, this will provide convenience to both the examiner and the patient when performing the examination, and it will contribute with its reproducibility.
