摘　　要：目的总结超声诊断脓肾的经验及不足,分析误诊原因。方法回顾分析行超声检查的11例经病理证实脓肾病例,其中手术病理证实7例,肾穿刺造瘘证实4例。归纳分析病例的临床及声像图特点。结果脓肾超声表现为:①患侧肾脏明显增大;②暗区内可见大量的细小飘浮光点或絮状沉积物回声;③肾实质明显变薄,回声增强;④肾活动度明显下降或固定;⑤常可发现梗阻因素。超声正确诊断7例,另4例误为重度肾积水,诊断符合率为63.6%。结论在充分掌握脓肾超声图像特征的基础上,充分结合病史及实验室资料,有助于提高脓肾检出率。Objective To analyze the characteristics of pyonephrosis on renal sonography. Methods The ultrasonic images of 11 cases that diagnosed as pyonephrosis by operation or percutaneous nephrostomy were analyzed retrospectively. Results The characteristics ofpyonephrosis on ultrasonic included： （1）obviously enlarged infected kidneys; （2）great amounts of small light-spots and floccular echo emerged in anechoic areas of kidneys; （3）thinned parenchyma of kidney with strengthened echo;（4） immobile infected kidneys; （5）ohstructed renal sonography. 7 cases were diagnosed as pyonephrosis, 4 eases were misdiagnosed as hydronephrosis, the accuracy was 63.6%. Conclusion Based on sufficiently understanding the characteristics of pyonephrosis on renal sonography, medical history and laboratory results are helpful to improve the accuracy of diagnosing pyonephrosis.
