摘　　要：目的::回顾性分析婴幼儿泌尿系结石螺旋CT平扫继发征象。方法:收集58例均进行螺旋CT平扫的婴幼儿泌尿系结石病例,由2名放射学家对所有病例进行回顾性分析,评估内容包括与泌尿系结石相关的继发征象如肾盂积水、近端输尿管扩张、肾脏增大、肾脏密度下降、肾周水肿、输尿管周围水肿。结果:58例泌尿系结石患儿中43例(74.1%)可发现与结石相关继发征象;其中肾积水29例(67.4%),近端输尿管扩张14例(32.6%),肾脏增大11例(25.6%),肾周水肿6例(14.0%),肾脏密度下降6例(14.0%),输尿管周围水肿5例(11.6%)。结论:螺旋CT既可直接观察泌尿系结石患儿的结石大小、密度、位置,又能对与泌尿系结石相关的继发征象进行观察。当诊断出现困难时,螺旋CT发现与泌尿系结石相关的继发征象可以帮助诊断。Objective To evaluate retrospectively the secondary signs of unenhanced helical computed tomography(HCT) of urinary system calculi in infant.Methods The study included 58 patients with urinary system calculi,all of them underwent the unenhanced CT scan.The patients were retrospectively evaluated by two radiology specialists.Assessment including secondary signs associated with urinary stones,such as hydronephrosis,proximal ureteral dilatation,renal enlargement,decreased renal density,perinephric edema,and periureteral edema.Results In the 58 patients,43 of them(74.1%) were found secondary signs associated with urinary system calculi.29 of them(67.4%) were hydronephrosis.14 of them(32.6%) were proximal ureteral dilatation.11 of them(25.6%)were renal enlargement.6 of them(14.0%)were perinephric edema.6 of them(14.0%)were decreased renal density.5 of them(11.6%)were periureteral edema.Conclusion HCT provided evaluation of the secondary signs associated with urinary system calculi as well as the direct visualization with regard to the size,density and position of the stones in cases with urinary system calculi disease.The ability of HCT to detect the secondary signs associated with urinary system calculi supported the diagnoses and may aid in diagnosis when difficulties are present.
