目的:探讨彩超引导下经皮肾镜术治疗不积水肾结石的应用价值,总结技术要点。方法:55例不积水肾结石患者,在彩超引导下建立标准经皮肾通道,采用EMS第四代碎石清石系统清除结石。结果:全部患者均成功建立通道,一期完成手术,一期结石清除率90.9%(50/55),2例残石较多者行二期PCNL,3例术后ESWL治疗。所有患者均未输血以及介入栓塞治疗。结论:彩超引导下行经皮肾镜术治疗不积水肾结石,可以有效降低术中、术后严重出血,安全可靠。
Objective: To explore the value of percutaneous nephrolithotomy guided by color Doppler ultrasonography in the treatment of hydronephrosis, and to summarize the technical points. Methods: Fifty-five patients with hydronephrosis were established. Standard percutaneous renal access was established under the guidance of color Doppler ultrasonography. The fourth generation of lithotripsy by EMS was used to remove stones. Results: The pathology was successfully established in all patients. The first stage of operation was completed. The first stage stone clearance rate was 90.9% (50/55). The second stage PCNL was 2 cases with more residual stone stones and the third postoperative ESWL treatment. None of the patients had blood transfusions or embolization. Conclusion: Percutaneous nephrolithotomy guided by color Doppler ultrasonography can treat hydronephrosis without hydrosphere, which can effectively reduce intraoperative and postoperative severe hemorrhage and is safe and reliable.
