儿童肾先天性异常的超声诊断价值

Diagnosis of congenital anomoly of pediatric kidneys by high frequency ultrasound

目的探讨小儿肾先天性异常的超声图像特征及其诊断价值。方法应用高频凸阵探头对118例肾先天性异常患儿进行检查，并分析其声像图特点。结果肾先天性异常的种类甚多，有数目、大小、位置、轴向、血管和肾盂的反常，本组118例小儿肾先天性异常中，超声诊断肾盂输尿管连接部狭窄72例，重复肾23例，一侧肾发育不全10例，一侧肾缺如7例，肾旋转反常1例，融合肾1例，双肾盂4例。结论应用高频超声对儿童肾先天性异常的诊断及鉴别诊断有一定的应用价值。

Objective To discuss the significance of high frequency ultrasound for diagnosis of congenital anomoly of pediatric kidneys. Methods Totally 118 patients with congenital anomoly of pediatric kidneys were examined with high frequency ultrasound, the characteristics of the images were analysed. Results Congenital anomoly kidneys had great diversity of variety in number,size,position,axial direction, abnormal vein and renal pelvis. In the 118 cases, pelvi-ureteric stenosis was in 72 cases,renal duplication in 23, renal hypoplasia in 10, kidney deficit in 7, rotatory anomaly in 1, fused kidney in l, and double renal pelvis in 4. Conclusions High frequency ultrasound is beneficial for diagnosing and differential diagnosing congenital anomoly of pediatric kidneys.
