摘要

目的分析肾石测量评分系统(GSS、STONE、CROES 和 S-ReSC)和结石表面对经皮肾镜取石术(PCNL)成功率和并发症的预测能力:我们对本中心接受 PCNL 的 392 例患者进行了研究。方法:我们对本中心接受 PCNL 的 392 例患者进行了研究,最终只分析了接受非对比 CT 检查的患者(240 例)。使用 ROC 曲线及其曲线下面积(AUC)评估了不同评分系统对成功率和并发症的预测能力:在成功率方面,S-ReSC 系统的预测能力最高,其 AUC 为 0.681(95% CI 0.610 - 0.751),其次是 CROES,为 0.667(95% CI 0.595 - 0.738),STONE 为 0.654(95% CI 0.579 - 0.728),最后是 GSS,为 0.626(95% CI 0.555 - 0.698)。结石表面作为单一变量的 AUC 为 0.641(95% CI 0.565 - 0.718)。在并发症方面,S-ReSC 的 AUC 最高,为 0.664 (95% CI 0.57 - 0.758),其次是 STONE,为 0.663 (95% CI 0.572 - 0.755),GSS 为 0.626 (95% CI 0.555).- 0.698),CROES 为 0.614(95% CI 0.518 - 0.7)。结石表面单独的 AUC 为 0.616(95% CI 0.522 - 0.715):结论:所分析的肾石量表对在本中心接受 PCNL 治疗的患者的成功率和并发症具有一定的预测能力。此外,结石表面作为一个独立变量,对这两种结果也有一定的预测能力。

Does success in percutaneous nephrolithotomy depend only on stone size? Analysis of the predictive capacity for success and complications of the current nephrolithometry scoring systems and their relationship with the stone surface

Objective

To analyze the predictive capacity of the nephrolithometry scoring systems (GSS, STONE, CROES and S-ReSC) and stone surface regarding success and complications following percutaneous nephrolithotomy (PCNL).

Methods

We studied 392 patients who had undergone PCNL in our center. Only patients with a non-contrast CT (n = 240) were finally included for analysis. The predictive capacities for success and complications of the different scoring systems were evaluated using ROC curves and their area under the curve (AUC).

Results

Regarding success, the S-ReSC system had the highest predictive capacity with an AUC of 0.681 (95% CI 0.610−0.751), followed by the CROES with 0.667 (95% CI 0.595−0.738), the STONE with 0.654 (95% CI 0.579−0.728) and finally the GSS with 0.626 (95% CI 0.555−0.698). The stone surface as a single variable had an AUC of 0.641 (95% CI 0.565−0.718). As for complications, the S-ReSC had the highest AUC with 0.664 (95% CI 0.57−0.758), followed by STONE with 0.663 (95% CI 0.572−0.755), GSS with 0.626 (95% CI 0.555).−0.698) and CROES with 0.614 (95% CI 0.518−0.7). The stone surface alone had an AUC of 0.616 (95% CI 0.522−0.715).

Conclusion

The nephrolithometry scales analyzed show a moderate predictive capacity for success and complications in patients undergoing PCNL in our center. Moreover, stone surface as an independent variable demonstrates moderate predictive capacity for both outcomes.
