摘　　要：目的探讨CT预测泌尿系结石硬度的可行性,为临床选择合理的治疗方法提供科学依据。方法选择2002年3月-2004年3月60例住院行开放手术的尿路结石患者,手术取出结石后测定平均CT值,以硬度计测定结石的硬度,将结石标本的平均CT值与其硬度值进行直线相关性分析。结果60枚结石平均CT值与其硬度值的Person相关系数为0.661,P=0.000。认为结石平均CT值与其硬度值间呈直线相关关系。结论结石平均CT值与结石硬度呈正相关关系,提示混合性结石CT值越高,其硬度就越大,可能所需碎石次数就越多。Objective This study investigates whether CT can be used to predict the hardness of the urinary calculi in order to provide scientific basis for choosing a reasonable treatment method. Methods 60 patients with urinary calculus were chosen randomly to measure the CT average value of these calculi after the surgical operation, then the hardness of calculi was measured with the sclerometer. And then CT average value and the hardness was analysed by linear correlation. Results The coefficient of CT average value and the hardness of the 60 sample stones was 0. 661, P = 0. 000, indicating a linear correlation. Conclusion There is a positive correlation between the CT average value and hardness. The results show that higher CT average value of stones requires more per-unit volume impact number.
