3D可视化技术在预测输尿管软镜碎石术后清石率的应用OA

Objective To compare the value of 3 D visualization technology versus CT non-contrast three-dimensional re-construction in the modified S.T.O.N.E.,S.O.L.V.E.,and SHA.LIN scoring systems for predicting stone-free rates(SFR)af-ter flexible ureteroscopic lithotripsy.Methods Clinical data from 163 patients with renal stones treated at our hospital between January and December 2024 were retrospectively analyzed.Preoperative 3D imaging and CT three-dimensional reconstruction were performed based on non-contrast CT scans,dividing patients into a 3D visualization group and a CT reconstruction group.Both groups were assessed using modified S.T.O.N.E.,S.O.L.V.E.,and SHA.LIN scores.Receiver operating characteristic(ROC)curves were plotted to analyze the predictive efficacy for stone clearance,and the area under the curve(AUC)was compared be-tween the two groups under identical scoring criteria.Results The overall stone-free rate(SFR)was 82.8％.Patients achieving stone-free status had significantly lower preoperative modified S.T.O.N.E.,S.O.L.V.E.,and SHA.LIN scores than those with residual stones(P＜0.05).The AUC values for all three scoring methods were significantly higher in the 3D visualization group than those in the CT reconstruction group(P＜0.05).Conclusion 3 D visualization technology outperforms CT three-dimensional reconstruction across all three scoring systems in predictive efficacy and demonstrates superior advantage in predicting SFR after flexible ureteroscopic lithotripsy.
