目的客观评价体外冲击波碎石术、经皮肾穿刺造瘘碎石取石术治疗肾结石的疗效。方法采用电子检索和手工检索进行文献初检,电子检索数据库有Medline data-base(1980年1月~2006年6月)、中国期刊全文数据库(CNKI,1980年1月~2006年6月)、中国循证医学/Cochrane中心数据库(CEBM/CCD)、Cochrane图书馆,手工检索近期《中华泌尿外科杂志》等4种杂志,鉴定有关随机对照试验,并采用RevMan4.2进行Meta-分析。结果我们共收集纳入2个随机对照试验进行了结石清除率的比较,177例病人符合纳入标准,Meta-分析结果显示经皮肾穿刺造瘘碎石取石术治疗肾结石(直径<3cm)在结石清除率方面明显高于体外冲击波碎石术。结论经皮肾穿刺造瘘碎石取石术治疗肾结石方面显示出了巨大的优势。
Objective To objectively evaluate the efficacy of extracorporeal shock wave lithotripsy and percutaneous nephrolithotomy in the treatment of kidney stones. Methods The preliminary examination of the literature was conducted by means of electronic retrieval and manual retrieval. The electronic retrieval database includes Medline data-base (January 1980 to June 2006), Chinese Journal Full-text Database (CNKI, January 1980 to June 2006) Cochrane Central Register of Evidence-Based Medicine / Cochrane Central Register (CBS) / Cochrane Central Library (Cochrane Central Library) and the Cochrane Library, and hand searched four recent journals such as Journal of Urology. Randomized controlled trials were identified and Meta-analysis was performed using RevMan 4.2. Results We collected a total of two randomized controlled trials for stone clearance, and 177 met the inclusion criteria. Meta-analysis showed that percutaneous nephrolithotripsy was used to treat kidney stones (diameter <3 cm) Clearance rate was significantly higher than extracorporeal shock wave lithotripsy. Conclusion Percutaneous nephrostomy lithotripsy showed great advantages in the treatment of kidney stones.
