Computed Tomography Radiomics-Derived Nomogram for Predicting Early Renal Function Decline After Partial Nephrectomy in Renal Cell Carcinoma: A Multicenter Development/Validation Study
- Conditions
- Renal Cell Carcinoma (RCC)
- Registration Number
- NCT07117786
- Brief Summary
The goal of this observational study is to explore the relationship between CT-based radiomics and postoperative renal function changes in patients with localized renal cell carcinoma (RCC) undergoing partial nephrectomy (PN). The main question it aims to answer is: Can a radiomics-clinical nomogram integrating CT-based radiomics features with preoperative and intraoperative clinical variables accurately predict early postoperative renal function decline in patients with localized RCC undergoing PN? Participants already undergoing renal CT examination and scheduled for postoperative renal function testing as part of the routine perioperative care will receive renal function assessment after completing surgical treatment for RCC.
