Contrast-enhanced Ultrasound and Super-resolution Imaging Predict Renal Function Outcome After Nephrectomy

The goal of this prospective cohort study is to evaluate the predictive value of Contrast-Enhanced Ultrasound (CEUS) and Super-Resolution Imaging (SRI) technologies regarding renal function outcomes in patients with renal cell carcinoma (RCC) undergoing partial or radical nephrectomy. The main questions it aims to answer are: Can quantitative parameters of renal microcirculation and microvascular structure derived from CEUS and SRI predict long-term renal function (defined as New Baseline eGFR for radical nephrectomy and Recovery from Ischemia for partial nephrectomy)? Can these imaging parameters accurately predict the occurrence, severity, and early recovery of postoperative acute kidney injury (AKI)? Researchers will monitor the dynamic evolution of renal blood flow and microvascular density by comparing the affected kidney to the contralateral healthy kidney before and after surgery to see if these biomarkers correlate with clinical outcomes. Participants will: Undergo CEUS and SRI examinations before surgery and at specific time points after surgery (e.g., within 7 days) to visualize renal microvasculature. Provide blood and urine samples for standard laboratory tests (such as serum creatinine and Cystatin C) to assess kidney function during hospitalization. Attend follow-up visits at 1, 3, 6, 9, and 12 months post-surgery to monitor long-term renal recovery and complete necessary imaging assessments (CT or Ultrasound).
