Tumour size outperforms nephrometry scores to predict surgical success following partial nephrectomy

Although lower R.E.N.A.L., PADUA, and SPARE NSs were associated with achieving surgical success and reduced risk of AKI, their predictive performance was modest and can be outperformed by a simpler and more objective measure, such as tumour diameter. Future studies remain necessary to re-evaluate the broader clinical utility of NSs in predicting surgical and functional outcomes, in addition to its original purpose as standardized tools for the anatomical characterization of renal tumours.
