摘要
目的分析彩色多普勒能量图(CDE)在引导肾穿刺活检中的利与弊,为进一步减少穿刺并发症积累经验。方法231例有穿刺指征的患者,按照随机原则分成灰阶超声引导组(112例)和CDE定位引导组(119例),记录分析进肾点位置、进针角度及并发症发生率等。结果112例CDE定位引导组中共有6例患者术后出现肉眼血尿和被膜下血肿,119例灰阶超声引导组中共有22例患者出现上述并发症。2种方法在降低穿刺并发症发生率方面有显著性差异(P<0.01)。结论单纯CDE实时引导穿刺过程中因组织移位造成彩色外溢干扰针尖位置的观察;CDE结合灰阶超声实时引导下肾脏穿刺活检,可以在高选择性确定进肾点和穿刺路线的同时保证监测的实时性,进一步减少穿刺出血等并发症。
Objective To analysis the advantages and disadvantages of color Doppler energy （CDE） in guilding renal automatic biopsy, explore a way to reduce the puncture complications. Methods 231 patients were separated into two groups at random. Patients in group one （112/231） were received renal automatic biopsy guided by gray scale ultrasound, while puncture operations for patients in group two （119/231） were guided by CDE. The rate of complication occurance, angles between kidney and puncture needle, and successful rates of obtaining specimens after renal biopsy were recorded. Results 6 of 112 patients in group one and 22 of 119 patients in group two were found out hematuria or perirenal hematomas after puncture operation. The result showed that CDE was superior to gray scale ultrasound in reducing renal biopsy complications, with marked difference （P〈0.01）. Complications after renal automatic biopsy have obvious relationship with puncture point and the angle between the kidney and puncture needle. Puncture times owe less help to hematuria and perirenal hematomas. Conclusions CDE alone had some disadvantages in guilding renal automatic biopsy, while CDE in cooperation with gray scale ultrasound was conformed useful in reducing hematuria and perirenal hernatomas.
