Abstract

Purpose: To develop a multivariate liniear model for predicting long-term (> 3 months) post-adrenalectomy renal function decline in patients with primary aldosteronism (PA). The model aims to help identify patients who may experience a significant decline in renal function after surgery.

Methods: We retrospectively analyzed the clinical data of 357 patients who were diagnosed with PA and underwent adrenalectomy between September 2012 and February 2023. LASSO and multivariate linear regression analyses were used to identify significant risk factors for model construction. The models were further internally validated using bootstrap method.

Results: Age (P < 0.001), plasma aldosterone concentration (PAC) measured in the upright-position (PACU, P = 0.066), PAC measured after saline infusion (PACafterNS, P = 0.010), preoperative blood adrenocorticotropic-hormone level (ACTH, P = 0.048), preoperative estimated glomerular filtration rate (eGFR, P < 0.001) and immediate postoperative eGFR (P < 0.001) were finally included in a multivariate model predictive of post-adrenalectomy renal function decline and the coefficients were adjusted by internal validation. The final model is: predicted postoperative long-term (> 3 months) eGFR decline =-70.010 + 0.416*age + 6.343*lg PACU+4.802*lg ACTH + 7.424*lg PACafterNS+0.637*preoperative eGFR-0.438*immediate postoperative eGFR. The predicted values are highly related to the observed values (adjusted R = 0.63).

Conclusion: The linear model incorporating perioperative clinical variables can accurately predict long-term (> 3 months) post-adrenalectomy renal function decline.

建立预测原发性醛固酮增多症患者肾上腺切除术后肾功能下降的多变量模型:一项大型队列单中心研究。
目的:建立一个多变量线性模型,用于预测原发性醛固酮增多症(PA)患者肾上腺切除术后长期(大于 3 个月)肾功能下降的情况。该模型旨在帮助识别术后肾功能可能显著下降的患者:我们回顾性分析了 2012 年 9 月至 2023 年 2 月期间确诊为 PA 并接受肾上腺切除术的 357 例患者的临床数据。我们使用 LASSO 和多变量线性回归分析来识别重要的风险因素,从而构建模型。采用引导法对这些模型进行了进一步的内部验证:年龄(P U,P = 0.066)、生理盐水输注后测量的 PAC(PACafterNS,P = 0.010)、术前血液促肾上腺皮质激素水平(ACTH,P = 0.048)、术前估计肾小球滤过率(eGFR,P 3 个月)eGFR 下降 =-70.010 + 0.416*age + 6.343*lg PACU+4.802*lg ACTH + 7.424*lg PACafterNS+0.637*preoperative eGFR-0.438*immediate postoperative eGFR。预测值与观察值高度相关(调整 R = 0.63):结论:包含围手术期临床变量的线性模型可准确预测肾上腺切除术后长期(大于 3 个月)的肾功能下降。

期刊介绍: The WORLD JOURNAL OF UROLOGY conveys regularly the essential results of urological research and their practical and clinical relevance to a broad audience of urologists in research and clinical practice. In order to guarantee a balanced program, articles are published to reflect the developments in all fields of urology on an internationally advanced level. Each issue treats a main topic in review articles of invited international experts. Free papers are unrelated articles to the main topic.
