摘要

背景:最近出现了几种评分系统来预测经皮肾镜取石术(PCNL)后无结石率(SFRs)。我们的目的是比较最常用的评分系统(Guy’s stone评分、stone肾结石测定仪和泌尿系统学会临床研究办公室(CROES) nomogram),并评估它们对无结石率(SFRs)的预测准确性。我们还评估了这些评分系统预测围手术期并发症、手术时间(OT)、住院时间(LOH)和术后血红蛋白下降的能力。方法:我们对50例连续两年在我院行PCNL的肾结石患者进行前瞻性评估。术前均行CT检查。我们对所有患者应用GSS、STONE肾结石测量和CROES图。评估这些评分系统与SFR、围手术期并发症、OT、LOH和血红蛋白下降的关系。结果:本研究的总SFR为94%。GSS、STONE和CROES的平均评分分别为1.66±0.71、7.08±1.77和86.9±4.35。与CROES图(AUC - 0.223)不同,GSS (AUC - 0.86)和S.T.O.N.E肾结石测定(AUC - 0.837)评分能有效预测SFR。总并发症发生率为54%。GSS (AUC - 0.643)和S.T.O.N.E肾结石测定(AUC - 0.628)评分与CROES nomogram (AUC - 0.308)评分不同,能有效预测术后并发症。三种评分系统(GSS、STONE和CROES)与OT均显著相关(P < 0.01)。没有一个评分系统与LOH相关。GSS和CROES图显示与Hb下降的相关性较弱。结论:与CROES图不同,GSS和STONE肾结石术能有效预测SFR和围手术期并发症。所有的评分系统都与加时赛有关。评分系统与LOH无关。GSS和CROES图与血红蛋白下降呈弱相关。

Comparative study between Guy's stone score, S.T.O.N.E nephrolithometry and Clinical Research Office of the Endourological Society (CROES) nephrolithometric nomogram in predicting stone-free rates in patients undergoing percutaneous nephrolithotomy: A prospective analysis
Background: Several scoring systems have recently emerged to predict stone-free rates (SFRs) after percutaneous nephrolithotomy (PCNL). We aimed to compare the most commonly used scoring systems (Guy's stone score, STONE nephrolithometry and Clinical Research Office of the Endourological Society (CROES) nomogram) and assess their predictive accuracy for stone-free rates (SFRs). We also evaluated these scoring systems in their ability to predict perioperative complications, operative time (OT), length of hospital stay (LOH) and postoperative fall in haemoglobin. Methods: We prospectively evaluated 50 consecutive patients with renal calculi who underwent PCNL at our institute for two years. Preoperative CT was done in all the patients. We applied GSS, STONE nephrolithometry and CROES nomogram in all patients. The association of these scoring systems with SFR, perioperative complications, OT, LOH and fall in haemoglobin was evaluated. Results: The overall SFR in our study was 94%. The mean score of GSS, STONE and CROES was 1.66 ± 0.71, 7.08 ± 1.77 and 86.9 ± 4.35. GSS (AUC – 0.86) and S.T.O.N.E nephrolithometry (AUC – 0.837) score effectively predicted SFR, unlike CROES nomogram (AUC – 0.223). The overall complication rate was 54%. GSS (AUC – 0.643) and S.T.O.N.E nephrolithometry (AUC – 0.628) score effectively predicted post-operative complications, unlike CROES nomogram (AUC – 0.308). All three scoring systems (GSS, STONE and CROES) significantly correlated with OT (P < 0.01). None of the scoring systems correlated with LOH. GSS and CROES nomogram showed a weak correlation with fall in Hb. Conclusion: GSS and STONE nephrolithometry effectively predicted SFR and perioperative complication, unlike the CROES nomogram. All scoring systems correlated with OT. Scoring systems did not correlate with LOH. GSS and CROES nomogram weakly correlated with fall in haemoglobin.
