彩色多普勒超声在肾脏弥漫性病变诊断中的价值

目的探讨彩色多普勒超声在肾脏弥漫性病变诊断中的价值。方法收集2013年6月至2014年6月于我院接受彩色多普勒超声检查的肾脏弥漫性病变患者80例,其中42例为急性肾病患者(急性组),另38例为慢性肾病患者(慢性组),另选择同期健康体检者20例作为对照组,检测三组受试者肾功能指标血清尿素氮(BUN)以及尿肌酐(Cr),对三组受试者行彩色多普勒超声检查,对比观察三组患者肾脏大小和肾皮质厚度,超声参数包括叶间动脉收缩期峰值流速(Vmax)、叶间动脉阻力指数(RI)和段动脉加速时间(AT)。结果三组BUN和Cr比较差异有统计学意义(均P0.05),急性组显著高于慢性组和对照组(均P0.05),慢性组显著高于对照组(P0.05);三组肾脏长、宽、厚和肾皮质厚度比较差异均有统计学意义(均P0.05),其中急性组肾脏长、宽、厚和肾皮质厚度显著高于慢性组和对照组(均P0.05),慢性组肾脏长、宽、厚和肾皮质厚度显著低于对照组(P0.05);三组叶间动脉Vmax、叶间动脉RI和段动脉AT比较差异均有统计学意义(均P0.05),其中急性组叶间动脉Vmax显著高于对照组和慢性组,而慢性组显著低于对照组,差异均有统计学意义(均P0.05);急性组叶间动脉RI、段动脉AT显著低于对照组和慢性组,而慢性组显著高于对照组,差异均有统计学意义(均P0.05)。结论肾脏弥漫性病变患者肾脏大小和肾皮质厚度均表现出一定程度的升高或降低,彩色多普勒超声技术可有效协助临床对肾脏慢性弥漫性患者的诊断、治疗及预后评估,且检查方法安全可靠、简便易行,无创伤,值得临床推广及应用。

The Value of Color Doppler Ultrasound in the Diagnosis of Renal Diffuse Lesions

Objective To study the value of Color Doppler ultrasound in the diagnosis of renal diffuse lesions.Methods 80 cases of diffuse lesions collected from 2013 June to 2014 June in my hospital underwent color Doppler ultrasonography of the kidney, including 42 cases of acute kidney disease patients (the acute group), another 38 cases of patients with chronic kidney disease (the chronic group), to explore the clinical value of color Doppler ultrasound in the diagnosis of renal diffuse lesions.Results There was statistically significant difference of BUN and Cr among the three groups(all P<0.05),acute group was significantly higher than chronic group and the control groups(all P<0.05),chronic group was significantly higher than that of control group (P<0.05);There was statistically significant difference of the length, width, thickness of kidney and renal cortical thickness among the three groups(all P<0.05),acute group was significantly higher than chronic group and the control groups(all P<0.05),chronic group was significantly lower than that of control group (P<0.05);There was statistically significant difference of Artery Vmax,RI and segment artery AT among the three groups(all P<0.05),arterial Vmax in acute group was significantly higher than chronic group and the control groups(all P<0.05),chronic group was significantly lower than that of control group (P<0.05);RI and segment artery AT in acute group was significantly lower than chronic group and the control groups(all P<0.05),chronic group was significantly higher than that of control group (P<0.05). Conclusion Color Doppler ultrasound technology can effectively assist clinical on renal chronic diffuse diagnosis, treatment and evaluation of prognosis of patients, and check method is safe and reliable, simple, non-invasive, is worth the clinical promotion and application.
