Accurately predicting new baseline-glomerular-filtration rate (NBGFR) after radical nephrectomy (RN) can improve counseling about RN vs partial nephrectomy. Split-renal-function (SRF)-based models are optimal, and differential parenchymal volume analysis (PVA) is more accurate than nuclear renal scans (NRS) for this purpose. However, there is minimal data regarding the limitations of PVA. Our objective was to identify patient/tumor-related factors associated with PVA inaccuracy.

实质体积分析用于估计肾根治性切除术后分裂肾功能和新基线 GFR 的局限性。

准确预测根治性肾切除术 (RN) 后新的基线肾小球滤过率 (NBGFR) 可以改善有关 RN 与部分肾切除术的咨询。基于分割肾功能 (SRF) 的模型是最佳的，并且差示实质体积分析 (PVA) 比核肾扫描 (NRS) 更准确。然而，关于 PVA 局限性的数据很少。我们的目标是确定与 PVA 不准确相关的患者/肿瘤相关因素。
