不同直径穿刺针对超声引导下经皮移植肾活检的影响

Effect of puncture needles with different diameter on percutaneous biopsy for transplant kidney under ultrasound guidance

    摘要
  • 摘要:
      目的  比较在超声引导下应用不同直径穿刺针行经皮移植肾活组织检查(活检)的效果。
      方法  接受超声引导下经皮移植肾穿刺活检的患者82例，按所用穿刺针直径将其分成两组，18 G组(31例)和16 G组(51例)。比较两组活检效果及并发症的发生情况。
      结果  与18 G组比较，16 G组的穿刺针数较少，且取得的肾小球数量较多(均为P＜0.01)。16 G组的取材合格率明显高于18 G组(P＜0.05)。两组患者术后并发症发生率比较差异无统计学意义(P＞0.05)。进一步分层比较，同为2针或3针穿刺时，两组的并发症发生率比较差异亦无统计学意义(均为P＞0.05)。
      结论  在超声引导下行移植肾穿刺活检，采用16 G穿刺针和18 G穿刺针穿刺的安全性相近。在患者病情的允许下，采用16 G穿刺针较18 G穿刺针更具有优势，肾取材标本的质量较高。

     

    Abstract:
      Objective  To compare the effect of puncture needles with different diameter on percutaneous biopsy for transplant kidney under ultrasound guidance.
      Methods  A total of 82 cases underwent percutaneous renal biopsy for transplant kidney under ultrasound guidance, and were divided into two groups based on the diameters of puncture needles, Group 18 G (n=31) and Group 16 G (n=51). The effect of biopsy and complications were compared between the two groups.
      Results  Compared with Group18 G, Group16 G used less puncture needles and obtained more glomeruli (both P＜0.01). The qualified rate of renal specimens in Group 16 G was significantly higher than that of Group 18 G(P＜0.05). There was no significant difference in postoperative complications between the two groups (P＞0.05). Further stratified comparison was conducted, and the results showed that complications of the two groups were not statistically significant in case of puncture with 2 needles or 3 needles (both P＞0.05).
      Conclusions   There is similar safety of 16 G puncture needle and 18 G puncture needle to perform renal biopsies under ultrasound guidance. Under the allowable condition of patients, 16 G puncture needle is superior to 18 G puncture needle and realizes high quality of renal specimens.
