目的以18G活检针为对照,评估经皮肾穿刺活检术应用16G活检针的安全性。方法 160例肾脏类疾病住院患者采用单盲法随机将患者分为16G针组80例和18G针组80例,均行肾穿刺活检,观察两组穿刺成功率及并发症。结果 16G针组穿刺成功率97.50%,明显高于18G针组成功率88.75%,差异有统计学意义(χ2=4.783,P<0.05);16G针组并发症发生率23.75%,18G针组并发症发生率23.75%,两组并发症发生率差异无统计学意义(P>0.05)。结论肾活检对于临床病理诊断肾脏类疾病有效性和安全性较好,16G活检针的活检成功率高于18G活检针,安全性与18G活检针相似。
Objective To evaluate the safety of 16G biopsy needle using percutaneous renal biopsy with 18G biopsy needle as control. Methods One hundred and sixty hospitalized patients with renal diseases were randomly divided into two groups: 80 cases of 16G needle group and 80 cases of 18G needle group. All patients underwent renal biopsy and the puncture success rate and complications were observed. Results The successful rate of puncture in 16G needle group was 97.50%, which was significantly higher than that in 18G needle group (88.75%), the difference was statistically significant (χ2 = 4.783, P <0.05). The complication rate of 16G needle group was 23.75% The incidence rate was 23.75%. There was no significant difference in the complication rates between the two groups (P> 0.05). Conclusion The renal biopsy is effective and safe for clinical diagnosis of renal diseases. The biopsy success rate of 16G biopsy needle is higher than that of 18G biopsy needle, which is similar to that of 18G biopsy needle.
