How Do We Work?

Identifying the origin of your kidney disease and/or kidney stones relies on a specialized assessment crucial for accurate diagnosis. This involves recommended blood tests, a 24-hour urine collection for urine analysis, and a cytobacteriological urine examination.

We start with detailed diagnostics to pinpoint your kidney condition.

At Renal Care Clinic, our initial step is to conduct a thorough diagnostic assessment to determine the underlying causes of your kidney disease or kidney stones. This involves a series of tests that may include:

  • Blood Tests: Essential for evaluating kidney function.
  • 24-Hour Urine Collection: To analyze kidney performance over a day.
  • Urine Culture: To detect any bacterial infections.
  • Imaging Techniques: We primarily use ultrasound to examine your kidneys and bladder. In certain cases, additional imaging like abdominal scans or urinary system scans may be required for a more detailed view.
  • Kidney Biopsy (when necessary): Involves taking a small tissue sample from your kidney for detailed analysis.

Customized treatments cater to your specific kidney health needs.

For Chronic Kidney Disease:
Our focus is on identifying the cause of reduced kidney function and implementing strategies to prevent further deterioration, potentially delaying or avoiding the need for dialysis.

For Kidney Stones:
We aim to determine the causative factors of stone formation and provide treatments to prevent recurrence and mitigate complications.

Advanced tools and ongoing management support your kidney health journey.

  • Remote Monitoring: We employ continuous remote monitoring to integrate your treatment into daily life, ensuring long-term, high-quality care.
  • Inbody Balance Assessment: A specialized tool to evaluate your body mass composition, offering insights into your cardiovascular risk.
  • AIDEWA® Smartbottle: This device tracks your hydration levels at home, playing a crucial role in your kidney health management.

We employ proven strategies to slow your kidney disease progression.

Adhering to ‘nephroprotection measures’ is crucial in slowing the progression of kidney disease. These include lifestyle modifications recommended by the KDIGO 2022 guidelines, such as regular physical activity, dietary changes, weight management, and smoking cessation. These measures are instrumental in preserving kidney function for an extended period.

Our integrated care plan focuses on comprehensive kidney health support.

For those with impaired kidney function, we offer comprehensive care plans in collaboration with your primary care physician and nephrologist. This integrated approach focuses on maintaining kidney health, minimizing the risk of cardiac complications, and enhancing overall well-being.
