目的 本研究旨在探讨压迫止血法在减少实时超声引导经皮肾穿刺术后并发症中的价值。方法 选取2011年9月1日—2016年12月31日于我院行超声引导下经皮肾穿刺术患者405例。按肾穿刺后是否行立即行压迫止血法分2组,非压迫止血法为对照组(A组),压迫止血法为研究组(B组)。记录患者术前血压、凝血四项、血红蛋白、血小板等指标。记录穿刺次数及每次穿刺所取标本长度。术后24 h复查穿刺点出血情况及肾周血肿情况。穿刺术后24 h内监测血尿情况。结果 与非采用压迫止血法超声定位经皮肾穿刺术后(A组)相比,压迫止血法术后(B组)并发症发生率较低, A组肉眼血尿发生率为8.8 %,B组为4 %,差异有统计学意义(P=0.048);A组24 h肾周血肿发生率为 62.1%,B组为49.8%,差异有统计学意义(P=0.042)。结论 实时超声引导下经皮肾穿刺后立即行压迫止血法,可有效减少术后肾周血肿和血尿。

Objective To discuss how to reduce the post-biopsy complications of real-time ultrasound-guided percutaneous renal biopsy by manual compression. Methods A total of 405 ultrasound-guided biopsies were performed in 404 patients in our hospital, between September 2011 and January 2017, were recruited to this study. They were divided into 2 groups, group A biopsy without manual compression, and group B biopsy with manual compression. All patients' records were retrospectively reviewed and both pre and post biopsy information, as well as complications were collected. Results The gross hematuria rate is 8.8 % (16 patients) in group A, but in group B, the rate is 4 %. The perirenal hematoma rate at 24 h after biopsy in group A detected by ultrasound is 62.1% (113 patients), and 49.8% (116 patients, P vs group A=0.042) in group B. Conclusion Manual compression to the puncture site reduced complications like perirenal hematoma and gross hematuria after real-time ultrasound-guided renal biopsy.
