Renal Medicine, also known as Nephrology, is a branch of medicine that deals with disorders and diseases of the kidney. Our department is staffed by a team of doctors, nurses and dieticians, providing a specialist service for our patients.

The conditions we treat

We diagnose and treat patients with many different kidney conditions including:

  • Acute kidney failure (also known as acute kidney injury or AKI)
  • Chronic kidney disease (also known as CKD)
  • Kidney failure requiring renal replacement therapy either as dialysis or a kidney transplant
  • High blood pressure that is unexplained or difficult to treat
  • Protein and / or blood in urine
  • Electrolyte problems (e.g. abnormal sodium, calcium and potassium levels)
  • Recurrent kidney stones where we investigate the cause and help prevent further kidney stones
