目的观察C臂机定位在经皮肾取石术(PCNL)穿刺引导中预防肾血管损伤的临床价值。方法选取行C臂机定位下PCNL术患者60例为观察组,患者进行旋转C臂机穿刺法建立皮肾通道,穿刺进针。选取行彩色多普勒超声引导下PCNL术患者60例为对照组,观察2组患者肾血管损伤情况。结果观察组肾血管损伤发生率为3.3%明显低于对照组的10.0%,差异有统计学意义(P<0.05)。2组患者术中、术后均无大出血和动静脉瘘等严重并发症发生。结论 C臂机定位下PCNL术能确切避开肾血管,提高手术安全性和精确性,有效减少PCNL手术并发症。
Objective To observe the clinical value of C-arm positioning in the prevention of renal vascular injury by percutaneous nephrolithotomy (PCNL). Methods Sixty patients undergoing PCNL under C-arm positioning were selected as the observation group. The patients underwent rotary C-arm puncture to establish the renal access and puncture the needle. Sixty patients with PCNL under the guidance of color Doppler ultrasound were selected as the control group, and the renal vascular damage was observed in the two groups. Results The incidence of renal vascular injury in observation group was significantly lower than that in control group (3.3% vs 3.3%, P <0.05). There were no serious complications such as hemorrhage and arteriovenous fistula in the two groups during operation and postoperatively. Conclusion PCNL under C-arm positioning can avoid the renal blood vessels, improve the safety and accuracy of the operation and reduce the complications of PCNL.
