摘要
目的探讨经腹壁超声与多层螺旋CT(MSCT)诊断小儿肾积水及对其肾功能的评估价值。方法选取本院2016年3月至2019年2月收治的60例小儿肾积水患者,收集患者临床及影像学资料。将CT检查和腹部超声的诊断结果进行讨论和分析;对比经CT检查和腹部超声对小儿肾积水的诊断准确性、敏感性和特异性。分析MSCT检查下不同胎儿泌尿外科学会(SUF)分级下血清肌酐水平(Scr),双肾实质厚度、患侧肾实质厚度比(rPRT)的差异变化,分析其相关性;分析腹部超声对患肾各方面的测量值对肾功能的影响。结果MSCT检查对小儿肾积水的诊断准确性、敏感性和特异性分别为90.00%、85.00%、88.33%,腹部超声检查对小儿肾积水的诊断准确性、敏感性和特异性分别为68.33%、63.33%、66.67%。MSCT检查对小儿肾积水的诊断灵敏性、特异性和准确性明显高于腹部超声检查。差异有统计学意义(P<0.05);中-重度患肾实质厚度较轻度患者显著变薄(P<0.05);中-重度患肾rRPT较轻度显著减低(P<0.05)。结论腹部超声和MSCT检查均可有效的显示小儿肾积水的影像学特点,但MSCT检查鉴别诊断小儿肾积水和对肾功能定量分析的能力优于腹部超声,临床可根据患儿个人情况来选择。
Objective To evaluate the value of transabdominal ultrasonography and MSCT in the diagnosis of hydronephrosis in children and its appraisal value on renal function.Methods 60 children with hydronephrosis admitted to our hospital from March 2016 to February 2019 were enrolled.Clinical and imaging data were collected.The diagnostic results of CT examination and transabdominal ultrasonography were discussed and analyzed.The diagnostic accuracy,sensitivity and specificity of CT and transabdominal ultrasonography in children with hydronephrosis were compared.The changes of Scr level,thickness of double renal parenchyma and rPRT in different classifications of SUF of MSCT were analyzed,and the correlation was analyzed.To analyze the effect of measured value in transabdominal ultrasonography on the renal function.Results The diagnostic accuracy,sensitivity and specificity of MSCT in children with hydronephrosis were 90.00%,85.00%,and 88.33%,respectively.The diagnostic accuracy,sensitivity and specificity of transabdominal ultrasonography in children with hydronephrosis were 68.33%.,63.33%,66.67%.The sensitivity,specificity and accuracy of MSCT examination were significantly higher than those of transabdominal ultrasonography.The difference was statistically significant(P<0.05).The thickness of renal parenchyma in moderate-tosevere patients was significantly thinner than that in mild patients(P<0.05),and the rRPT in moderate-to-severe patients was significantly lower than that in mild patients(P<0.05).Conclusion Transabdominal ultrasonography and MSCT examination can effectively show the imaging features of hydronephrosis in children,but the ability in differential diagnosis of hydronephrosis in children and quantitative analysis of renal function is better than transabdominal ultrasonography.They can be selected according to the individual condition of the patients in clinic.
