【摘要】 目的 评价超声背向散射积分对肾组织轻微病变的诊断价值。 方法 用超声背向散射积分检测尿常规指标异常但肾功能指标正常、二维B超检查双侧肾脏正常的患者30例和健康自愿者24例;对患者施行B超导引下经皮肾脏穿刺活检术。 结果 超声背向散射积分检测发现患者双侧肾实质IBS值和IBS%值均增高，肾窦区无明显变化。病理活检证实患者存在肾组织微观结构的改变。 结论 超声背向散射积分作为一种超声检测新技术，对肾组织轻微病变可做出早期诊断;可用于病理活检风险性大、难以开展病理活检或者没有必要确定病理分型的组织轻微病变的诊断。

    【Abstract】 Objective To evaluate the diagnostic value of integrated backscatter in mild changes of renal tis-sue.Methods Ultrasonic integrated backscatters were performed on the24healthy cases and on the30patients who were abnormal in urinal routine examination.The patients were undergone percutaneous renal biopsy inducted by B-mode ultrasound.Results There was significant increase in the value of IBS and IBS%of renal parenchyma in pa-tients and there was no significant change in the renal sinus.There were pathologic changes of renal parenchyma in the patient which confirmed by percutaneous renal biopsy.Conclusion As a new method for clinic examination ......
