【摘要】：目的分析低剂量多排螺旋CT尿路成像技术(CTU)对尿路病变的诊断价值。方法选取2015年1月—2016年7月在嘉应学院医学院附属医院行CTU检查的患者270例,按照入院顺序分为A组、B组和C组,每组90例。A组、B组、C组患者分别采用160 m A、120 m A、80 m A管电流进行CTU。分析CTU对3组患者尿路病变的诊断效能,比较3组患者辐射有效剂量、碘对比剂用量及CTU成像效果评分。结果 3组患者中,CTU诊断尿路结石、泌尿系统畸形、肾肿物的灵敏度、特异度、阳性预测值、阴性预测值均为100.00%,约登指数均为1.00。A组患者中,CTU诊断尿路上皮癌的灵敏度为94.73%,特异度为100.00%,阳性预测值为100.00%,阴性预测值为89.47%,约登指数为0.95;B组患者中,CTU诊断尿路上皮癌的灵敏度为95.00%,特异度为100.00%,阳性预测值为100.00%,阴性预测值为100.00%,约登指数为0.95;C组患者中,CTU诊断尿路上皮癌的灵敏度为94.73%,特异度为100.00%,阳性预测值为100.00%,阴性预测值为97.22%,约登指数为0.94。C组患者辐射有效剂量和碘对比剂用量低于A组和B组,B组患者辐射有效剂量和碘对比剂用量低于A组(P0.05)。3组患者肾盏、肾盂、上段输尿管、中段输尿管、下段输尿管、膀胱CTU成像效果评分比较,差异均无统计学意义(P0.05)。结论低剂量CTU能满足尿路病变成像需求,对尿路病变的诊断价值较高。
[Abstract]:Objective to analyze the diagnostic value of low dose multi-slice spiral CT urography (CTU) in the diagnosis of urinary tract diseases. Methods from January 2015 to July 2016, 270 patients underwent CTU examination in the affiliated Hospital of Jiaying College of Medicine. According to the order of admission, the patients were divided into two groups: group A (n = 90) and group C (n = 90). CTU was performed with 160mAm 120mAn 80mA tube current in each group. The diagnostic efficacy of CTU in the diagnosis of urinary tract diseases was analyzed, and the effective doses of radiation were compared among the three groups. Results the sensitivity, specificity, positive predictive value of urolithiasis, urinary system malformation, renal mass were detected in 3 groups. The negative predictive value was 100.00. the Yorden index was 1.00.A group. The sensitivity, specificity, positive predictive value and negative predictive value of CTU in the diagnosis of urothelial carcinoma were 94.73, 100.00, 100.00and 89.47, respectively. In group Yoten, CTU was used in the diagnosis of urothelial carcinoma. The sensitivity, specificity, negative predictive value and negative predictive value of CTU in group C were 94.73, 100.00, 100.00, 100.00, 97.2222 and 97.222.The sensitivity, specificity, positive predictive value, negative predictive value and negative predictive value of CTU in group C were 94.73, 100.00,100.00,100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g, 100.00g and 100.00g, respectively. The index of effective dose of radiation and dosage of iodine contrast agent in group C were lower than those in group A and group B were lower than those in group A and group B were lower than those in group A and group B, respectively, and the dosage of iodine contrast agent in group B was lower than that in group A (P 0.05). There was no significant difference in the CTU imaging scores of renal pelvis, upper ureter, middle ureter, lower ureter and bladder. Conclusion low dose CTU can meet the need of urological imaging, and has a higher diagnostic value for urinary tract lesions.
