Summary
Aortic calcification index (ACI) predicts kidney function decline after radical nephrectomy for renal cell carcinoma (RCC). Higher ACI levels indicate a greater risk of chronic kidney disease (CKD) development post-surgery.
Area of Science:
- Nephrology
- Cardiovascular Radiology
- Oncology
Background:
- Radical nephrectomy for renal cell carcinoma (RCC) increases the risk of chronic kidney disease (CKD).
- Preoperative assessment of renal function is crucial to anticipate postoperative decline.
- The aortic calcification index (ACI) as a predictor of renal function deterioration remains under investigation.
Purpose of the Study:
- To investigate the association between the aortic calcification index (ACI) and the risk of renal function deterioration after radical nephrectomy for RCC.
- To determine if ACI can predict the development or worsening of chronic kidney disease (CKD) post-surgery.
Main Methods:
- Retrospective analysis of 109 patients undergoing radical nephrectomy for RCC with at least five years of renal function follow-up.
- Patients were categorized into non-CKD and pre-CKD groups based on preoperative estimated glomerular filtration rate (eGFR).
- Aortic calcification index (ACI) was measured using abdominal computed tomography; patients were stratified by low and high ACI levels. Renal function deterioration-free interval rates were evaluated using Kaplan-Meier analysis and multivariate analysis.
Main Results:
- Higher ACI (≥8.3%) was significantly associated with eGFR decline in both non-CKD and pre-CKD groups.
- Patients with high ACI showed significantly lower renal function deterioration-free interval rates compared to those with low ACI.
- Multivariate analysis identified higher ACI as an independent risk factor for renal function deterioration five years post-radical nephrectomy.
Conclusions:
- The burden of aortic calcification is a potential predictor of renal function deterioration following radical nephrectomy.
- ACI may serve as a valuable tool for risk stratification in patients undergoing nephrectomy for RCC.
- Further research is warranted to confirm ACI's role in managing patients at risk for CKD post-nephrectomy.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

526
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
