体外冲击波碎石术与微创经皮肾镜取石术治疗肾下盏结石疗效比较

目的比较体外冲击波碎石术(ESWL)与微创经皮肾镜取石术(mPCNL)治疗肾下盏结石的临床效果。方法 75例肾下盏结石患者,54例行ESWL(ESWL组),21例行mPCNL(mPCNL组),比较2组的结石清除率及并发症。结果 ESWL组的结石清除率为31.5%,mPCNL组的结石清除率为76.2%,mPCNL组结石清除率显著高于ES-WL组(P<0.05)。ESWL组出现不同程度的肉眼血尿48例,发热6例,肾周血肿2例;mPCNL组出现术后迟发性出血1例,尿路感染3例。结论 mPCNL治疗结石直径1.0～2.0 cm的肾下盏结石清除率高于ESWL,且并发症少。

Comparison of the effect of extracorporeal shock-wave lithotripsy and minimally invasive percutaneous nephrolithotomy for kidney lower calycal calculi

Objective To compared the clinical effect of extracorporeal shock-wave lithotripsy(ESWL) and minimally invasive percutaneous nephrolithotomy(mPCNL) for kidney lower calycal calculi. Methods Among Seventy-five patients with kidney lower calycal calculi,fifty-four patients in ESWL group were treated with ESWL,twenty-one patients in mPCNL group were treated with mPCNL,the stone clearance and complication were compared between two groups. Results The stone clearance of ESWL group and mPCNL group was 31.5% and 76.2% respectively,the stone clearance of mPCNL group was significantly higher than that of ESWL group(P<0.05).In ESWL group,the complications included forty-eight cases of varying degrees of gross hematuria,six cases of fever,two cases of perirenal hematoma;in mPCNL group,the complications included one case of delayed hemorrhage after operation and three cases of urinary tract infection. Conclusion For the patients with kidney lower calycal calculi with stone diameter of 1-2 cm,the stone clearance of mPCNL is higher than that of ESWL,and the complication is few.
