目的:探讨低温下肾蒂阻断肾实质切开取石术在复杂性肾结石治疗中的应用。方法:选择复杂性肾结石患者25例,阻断前静脉注射肌苷2.0g,均采用低温下阻断肾蒂,沿Brodel线作肾实质切开取石术。结果:25例肾蒂阻断17～45min,术中出血150～450ml,手术时间100～160min,结石残留2例。术后随访6个月～4年,术后肾功能恢复良好。结论:低温肾蒂阻断肾实质切开取石术是治疗复杂性肾结石的重要方法,结石取净率高,并发症少,对肾功能无影响。
Objective: To explore the application of renal pedicle block renal cryogenic lithotomy in complex renal calculus. METHODS: Twenty-five patients with complex renal calculi were selected. The inosine 2.0g was blocked by anterior intravenous injection. The renal peduncle was blocked at low temperature and the renal parenchyma was taken along the Brodel line. Results: 25 cases of renal pedicle block 17 ~ 45min, intraoperative bleeding 150 ~ 450ml, operation time 100 ~ 160min, residual stones in 2 cases. Follow-up 6 months to 4 years after surgery, renal function recovered well. CONCLUSION: Low-temperature renal pedicle block renal parenchyma lithotripsy is an important method for the treatment of complex renal calculus. High rates of stone removal, fewer complications and no effect on renal function.
