目的. - 回顾性评估放射学参数在输尿管镜检查（URS）计划中作为单次输尿管软镜检查后无结石状态预测因子的临床实用性。- 回顾性评价了67例采用弹性URS治疗的肾结石患者。为了评估放射学参数的临床效用，采用受试者工作特征曲线下面积和Logistic回归分析无结石（SF）状态与结石负荷（最大直径、计算面积、计算体积、累积直径和三维体积[V3D]）之间的关系。- 最大直径（AUC = 0.75）、计算面积（AUC = 0.79）、计算体积（AUC = 0.79）、累积直径（AUC = 0.80）和三维体积（AUC = 0.82）可预测URS后SF状态。- 结石负荷评估对于预测单次URS后的SF状态至关重要。平面和体积测量显示出相同的能力来预测SF状态。V3D更准确，但在临床实践中直径测量仍然更容易。(C)2017年Elsevier Masson SAS。All rights reserved.
Purpose. - To retrospectively assess the clinical utility in ureteroscopy (URS) planning of radiological parameters as predictor of stone-free status after a single flexible ureteroscopy.Material. - Sixty-seven patients with renal stones treated by flexible URS were retrospectively evaluated. To assess the clinical utility of radiological parameters, relationships between stone-free (SF) status and stone burden (maximal diameter, calculated area, calculated volume, cumulative diameter, and tridimentionnal volume [V3D]) were analyzed using the area under the receiver operating characteristics curve and logistic regression.Results. - Maximal diameter (AUC = 0.75), calculated area (AUC 0.79), calculated volume (AUC = 0.79), cumulative diameter (AUC = 0.80) and tridimensional volume (AUC = 0.82) revealed ability to predict SF status after URS.Conclusion. - Stone burden evaluation is critical in predicting SF status after a single URS. Planar and volumetric measurements showed equal ability to predict SF status. V3D is more accurate but diameter measurement remains easier in clinical practice. (C) 2017 Elsevier Masson SAS.
