彩超引导下使用16 G和18 G Cru-cut手动活检针肾组织活检结果比较

Comparative Study of 16 G(gauge)cru-cut Needle and 18 G Cru-cut Needle Renal Biopsies by Color Doppler Ultrasound Guidiance

目的:为了研究穿刺针粗细对肾活检穿刺成功率及并发症的影响。方法:156例患者随机分成两组,1组80例,用16 G Cru-cut针;2组76例,用18 G Cru-cut针进行彩超引导下肾组织活检。结果:1组穿刺成功率97.5%;平均穿针次数(2.36±0.23)针;并发症11.3%(肉眼血尿8.8%,被膜下血肿2.5%)。2组穿刺成功率97.4%;平均穿针次数(3.39±0.50)针;并发症10.5%(肉眼血尿7.9%,被膜下血肿2.6%),两种方法成功率、术后并发症没有统计学意义(P>0.05),两组穿针次数差异有统计学意义(P<0.01)。1组每条肾组织中肾小球个数17.24±5.21;每例肾小球总数29.36±7.31,2组每条肾组织中肾小球个数11.37±3.13;每例肾小球总数21.81±6.43,两组每条肾组织中肾小球个数及每例肾小球总数比较差异有统计学意义(P<0.05)。结论:使用16 G针进行超声引导下肾活检没有增加并发症,与18G针一样安全,而且可以获得更多的肾小球。

Objective：To compare affection in success rates and complications of using thick needles and fine needles in renal biopsies Methods：146 subjects were divided into two groups in a randomized manner,Group1 80 subjects received a 16G cru-cut needles biopsy while Group2 76 subjects received a 18G cru-cut needles biopsy by color Doppler ultrasound guidance.Results：In group1,success rates was 97.5%;complications were 11.3%（cross hematuria was8.8%,perirenal hematoma was2.5%）.In group 2 success rates was 97.4%;complications were10.5%（cross hematuria were 7.9%,perirenal hematoma were 2.6%）respectively,these results no significant difference.,In group1the number of cores was 2.36± 0.23;In group2 the number of cores was3.39±0.5;the number of cores was has significant difference in two groups（P〈0.01）.the number of glomeruli per core and the total glomeruli number has significant difference in two groups 16G group were（17.24±5.21）,（29.36±7.31）;18G group were（11.37±3.13,21.81±6.43）（P〈0.05）.Conclusion：16G needles performing renal biopsy was as safe as 18 G needles,moreover,it can get more glomerulies did not hence the complications.
