Early characterization of small (T1a, <4 cm) renal masses is imperative for patient care and treatment planning. Renal biopsy is a sensitive and specific procedure that can accurately differentiate small renal masses as malignant or benign. However, it is an invasive procedure with a nonnegligible complication rate and is not performed routinely at most institutions.

- - Renal cell carcinoma (RCC) is the most prevalent kidney cancer, but a formal scoring system for assessing neovascularity—a key factor in its metastasis—didn't exist until this study.
- - Researchers analyzed angiogenesis in kidneys affected by RCC and developed a new scoring scale (0-4) to quantify neovascularity, correlating higher scores with more advanced tumor stages.
- - The study included 227 patients, showing significant differences in neovascularity scores between various tumor stages and benign kidneys, suggesting that this new scoring system can enhance radiological assessments and clinical decisions regarding RCC.
