探讨超声实时引导下“十字定位法”肾穿刺活检术在基层医院的临床应用价值。

回顾分析上海新华医院崇明分院超声科2018年1月至2019年12月105例超声实时引导下“十字定位法”肾穿刺活检患者的成功率、穿刺活检肾小球数量及术后并发症发生率。

105例肾穿刺活检术患者中，除1例患者穿刺病理提示为脂肪组织，其余患者肾活检均获得10个以上的肾小球数，肾穿刺活检成功率为99%（104/105）。全组术后超声检出肾周及包膜下血肿25例（23.8%，25/105），其中，血肿长径＞25 mm者5例；肉眼血尿者7例（6.7%，7/105），总并发症发生率为30.5%（32/105）。

基层医院开展超声实时引导下“十字定位法”肾穿刺活检术安全、有效，具有一定的临床应用价值。

To assess the clinical application of real-time ultrasound-guided "cross positioning" renal biopsy in primary hospitals.

The success rate, the number of glomeruli, and the incidence of postoperative complications in 105 patients who underwent "cross positioning" renal biopsy under real-time ultrasound guidance at the Department of Ultrasound of Chongming Branch of Shanghai Xinhua Hospital from January 2018 to December 2019 were analyzed retrospectively.

In the 105 cases of renal biopsy included, more than ten glomeruli were obtained except one case in whom fat tissue was obtained. The success rate of renal biopsy was 99% (104/105). Twenty-five (23.8%, 25/105) cases of perirenal hematoma and subcapsular hematoma were detected by ultrasound, including five cases with hematoma larger than 25 mm and seven (6.7%, 7/105) with gross hematuria; the total complication rate was 30.5% (32/105).

It is safe and effective to carry out "cross positioning" renal biopsy under the guidance of real-time ultrasound in primary hospitals.
