摘　　要：目的探讨cT值对于输尿管下段结石选择治疗方法的价值。方法选择不同CT值的三组（A组HU〈700，B组HU700—1000，C组HU〉1000）输尿管下段结石的患者，分别行体外碎石（ESWL）＋药物治疗，治疗后有变化但还有未排出的结石，间隔10～14d后再行2次或3次ESWL。治疗后3～6个月复查。结果A组（n=45）患者中43例结石排出占95．6％，B组（n=31）患者中23例结石排出，占74．2％，C组（n=36）患者中15例患者结石排出占41．7％，均未出现明显并发症。结论输尿管下段结石的CT值对指导治疗方法的选择有重要价值，HU〈700的患者应首选ESWL。Objective To explore the role of CT Hounsfield unit （Hn） of stone in the choice of treatment methods to lower urethral calculi, for the improvement in treatment efficiency.
