[摘要] 目的 研究尿路結石患者采用非增強螺旋CT檢測結石CT值對尿路結石體外沖擊波碎石（ESWL）后排石效果的預測價值。 方法 方便選取82例該院2013年9月—2015年9月期間收治的尿路結石患者作為研究對象，所有患者均采用CT檢測結石CT值，并進行ESWL治療。根據治療后結石排空情況分為結石排空組（n=48）和結石殘留組（n=34），統計兩組患者基本特征、結石CT值以及能量沖擊次數，分析結石CT值對患者ESWL治療效果的預測價值。結果 結石排空組平均CT值、能量平均沖擊次數為（581.62±163.44）HU、（1 528.69±463.24）次，結石殘留組分別為（1 028.95±256.73）HU、（2 608.35±514.68）次，差異有統計學意義（P<0.05）。結論 結石CT值可預測尿路結石患者ESWL治療后結石排空效果，CT值越低，ESWL治療后結石排空率越高，結石CT值對尿路結石ESWL治療效果具有重要預測價值。

[Abstract] Objective To research the predicative value of CT value test on the extracorporeal shock wave lithotripsy effect of patients with lithangiuria. Methods Conclusion selection 82 cases of patients with lithangiuria admitted and treated in our hospital from September 2013 to September 2015 were selected and the stone CT value was tested by CT， and the patients were treated with ESWL， and the patients were divided into the stone evacuation group with 48 cases and stone residual group with 34 cases according to the stone evacuation conditions， and the basic features， stone CT value and energy impulse frequency of the two groups were counted and the predictive value of stone CT value on the ESWL treatment effect was analyzed. Results The differences in the average CT vale and average energy impulse frequency between the stone evacuation group and the stone residual group were statistically significant[（581.62±163.44）HU， （1 528.69±463.24） vs （1 028.95±256.73）HU， （2608.35±514.68）]（P<0.05）. Conclusion The stone CT value can predict the stone evacuation effect of patients with lithangiuria after the ESWL treatment， the lower the CT value， the higher the stone evacuation rate after the ESWL treatment and the stone CT value is of important predictive value to the lithangiuria ESWL treatment effect.

體外沖擊波碎石術（ESWL）憑借其安全性高，速度快，治療便捷，痛苦小等優勢，在臨床上廣泛運用，成為泌尿系結石治療的常用方法之一[1]。但有研究顯示[2]，仍然有一些泌尿系結石僅采用ESWL碎石治療效果并不理想。因此ESWL治療具有一定的適應癥。為進一步研究ESWL治療的最佳適應癥，減少臨床治療的重復性，節省醫療資源，該文對該院2013年9月—2015年9月期間收治的82例尿路結石患者進行研究，采用增強螺旋CT檢查患者結石的CT值，探討結石CT值對ESWL治療的預測價值，現報道如下。
