Background: To explore new factors that are predictive of post-partial nephrectomy (PN) renal global function, we analyzed various clinico-pathological factors with a special focus on renal volume measured via three-dimensional imaging technology and histopathological parameters in non-neoplastic parenchyma. Methods: Estimated glomerular filtration rate (eGFR) and computed tomography (CT) scan were examined pre- and 6 months. post-operatively in 52 patients treated by PN. The post-operative percent eGFR decline was employed as the measure of global renal functional deterioration. The novel factors analyzed included the percent renal parenchymal volume decline of the diseased side, contralateral and bilateral sides and the global glomerulosclerosis (GS) extent in non-neoplastic parenchyma. Renal parenchymal volumetry by CT scan was performed using SYNAPSE VINCENT (Fujifilm). Additional factors analyzed included patient demographics and comorbidities, surgical factors and tumor pathology. All factors demonstrating significant tendencies (P < 0.1) in univariate analyses were subjected to multivariate logistic regression analysis. Results: Two groups were categorized according to the degree of eGFR decline. Groups A and B were categorized as less than 15% and greater than 15% decline, respectively. Pre-operative eGFR was significantly lower in group B than in group A. Greater than 10% global GS extent in non-neoplastic parenchyma, male gender and proteinuria were significantly more frequent in in group B than in group A. The renal volume change was not statistically significant. In multivariate logistic regression analysis, greater than 10% global GS extent in non-neoplastic parenchyma was the sole independent affecting factor for Group B. Conclusion: Our study suggested that host factors rather than surgical factors may be useful for the prediction of post-PN renal global function. The evaluation of the global GS extent in non-neoplastic parenchyma is a promising biomarker of post-PN renal global function.
