The Feasibility of CT Attenuation Value to Predict the Composition of Upper Urinary Calculi and Success Rate of Extracorporeal Shock Wave Lithotripsy
摘要
Abstract
Objective To explore the feasibility of CT attenuation value (CT-value) to predict the composition of upper urinary calculi and the number of shock waves (NSW) and success rate (SR) of extracorporeal shock wave lithotripsy (ESWL).Methods A total of 146 patients with upper urinary calculi treated by ESWL were included.CT scan was performed before ESWL.Upper urinary calculi with the maximum diameters of less than or equal to 2 cm were included.Infrared spectroscopy was used to analyze the composition of calculi.The effect of ESWL was estimated at 1 month follow-up.The factors that influence NSW and SR of ESWL were analyzed by correlation analysis.Results The CT-value of calcium calculi were larger than that of non-calcium calculi (P＜0.001).The differences of NSW,SR of ESWL and CT-values of calculi between the patients with different ages,skin-to-stone distances and genders were not statistically significant.The partial correlation analysis found that CT-value and long diameter of calculi were positively correlated with the NSW (P＜0.05).This result was consistent in subgroup analysis (stone site.:kidney or ureter).CT-value and long diameter of calculi were negatively correlated with SR of ESWL (P＜0.05).However,the CT-value of ureteral calculi was not correlated with SR of ESWL in subgroup analysis.Conclusions The power of CT-value to predict upper urinary calculi composition is insufficient.Higher CT-value suggests more NSW in ESWL,but CT-value is not suitable to predict SR of ESWL.关键词
