The Value of CT Urologic Imaging in the Clinical Diagnosis and Treatment of Ureteral Stones
Objective:To analyze the value of CT urological imaging in the clinical diagnosis of ureteral stones.Methods:200 patients with stones attending the hospital from January 2019 to January 2021 were selected as the study subjects,and plain ab-dominal film examination and enhanced high-end CT examination were implemented in all patients respectively.The diagnostic value of the 2 examinations was analyzed.Results:The sensitivity of transabdominal plain film examination was 72.22%,the specificity was 52.34%,the positive predictive value was 46.02%cases,and the negative predictive value was 77.01%,which was significantly higher than 95.83%,93.75%,89.61%,and 97.56%of the enhanced high-end CT examination,and the difference was statistically significant(χ2=18.358,63.445,44.522,25.654,P＜0.05).Of the 200 patients,70 patients had stones in the upper ureter,35 patients in the middle,83 patients in the lower,12 patients had multiple stones in one side of the ureter,83 patients had stones in the left ureter,87 patients in the right,and 30 patients in the right and left ureters.In 200 patients,the smallest stone was 1.5 mm and the largest was 48.5 mm.Factors related to ureteral length did not show some correlation with age,and the difference was not statistically significant(χ2=0.010,P＞0.05).Height and gender were the main determinants of ureteral length,and the difference was statistically significant(χ2=19.048,31.348,P＜0.05).Conclusion:Enhanced high-end CT examination of patients with ureteral stones can be of significant value,and can provide an important foundation for improving diagnostic accuracy and,in turn,for preoperative preparation of D-J tubes of appropriate length in patients with stones.
