微创腔镜技术治疗结石性脓肾46例疗效分析

目的探讨用微创腔镜技术治疗结石性脓肾的疗效。方法结石性脓肾患者46例，其中32例采用微创经皮肾镜取石术，11例采用经尿道输尿管镜取石术，3例同时采用微创经皮肾镜取石和经尿道输尿管镜取石术治疗。结果术后40例获得随访6个月。5年，患肾功能恢复或部分恢复31例（77．5％），患肾萎缩（无功能）7例（17．5％），患肾切除2例（5％）。结论腔镜技术治疗结石性脓。肾是安全、有效的；早期诊断、及时引流、解除梗阻是结石性脓肾保肾治疗的关键。

Treatment of calculous pyonephrosis with minhnally invasive endoscopic technique

Objective To investigate the feasibility of treatment of calculous pyonephrosis with minimally endoscopic technique. Methods 46 cases of calculous pyonephrosis were treated by endoscopic technique （32 by mini-percutancous nephrolithotomy, 11 by transurethral ureteroscopy,3 by mini-percutancous nephrolithotomy and transurethral ureteroscopy together）. Results 40 cases have been followed up for 6 months to 5 years. The renal function improved in 77.5%（31/40）. Renal atrophy was observed in 17.5% （7/40） and nephrectomy in 5% （2/40）. Conclusion It is safe and effective to treat calculous pyonephrosis with endoscopic technique.The key to the treatment of calculous pyonephrosis by kidney-sparing operation is early diagnosis ,timely drainage and relief of obstruction.
