摘要
目的探讨影响上尿路结石体外冲击波碎石(ESWL)预后的因素。方法回顾性分析ESWL治疗上尿路结石患者366例的临床资料。治疗结果在随访3月时评估,结石完全排出视为治疗成功,未排或有残石为治疗失败。分析患者及结石特征如性别、年龄(年龄段)、身高、体重、体重指数、病程、疼痛、血尿、结石位置、结石侧别、结石长度、结石宽度等因素与治疗成功率的关系。结果366例碎石成功率63.4%(232/366)。应用χ2检验及t检验比较两组术前资料,发现病程、结石长度及结石宽度是有意义因素,Logistic多因素回归分析排除了结石宽度和病程,说明结石长度是影响体外冲击波碎石的独立因素。结论结石大小是影响上尿路结石ESWL预后的最主要因素。
Objective To investigate the factors affecting the efficacy of extracorporeal shockwave lithotripsy （ESWL） for upper urinary tract stones. Methods Between January 2003 and January 2006, 366 patients with upper urinary tract stgne underwent ESWL, and the results were identified by regular KUB/IVU or ultrasonography and evaluated 3 months after the treatment. The treatment success was defined as complete clearance of the stones without residual fragments. The stone-free rate was analyzed in relation to the stone features and the patients＇ clinical characteristics, and the factors identified to significant affect the results were further analyzed using multivariate regression analysis. Results Three months after the treatment, the overall stone-free （success） rate was 63.4% （232/366） in these patients. Chi square test and t test identified the disease course, stone length and width as the factors with significant impact on the stone-free rate. Multivariate analysis excluded the disease course and stone width from the logistic regression model, and identified the stone length as the independent factor affecting the outcome of ESWL. Conclusion The stone length is an independent factor influencing the efficacy of ESWL for upper urinary tract stones.
