Nephrologists deal with function and diseases of the kidney which do not require surgery. This concerns the diagnosis and treatment of kidney diseases, management of blood salt balance,  hypertension and giving renal support and replacement therapy, including dialysis and renal transplant patients.

Many diseases affecting the kidney are systemic disorders and not limited to just one organ itself and may require special treatment from other specialists. Patients are referred to nephrology specialists for various reasons, such as:

  • Acute renal failure, a sudden loss of renal function
  • Chronic kidney disease, declining renal function, usually with an inexorable rise in creatinine.
  • Haematuria, blood in the urine
  • Proteinuria, the loss of protein especially albumin in the urine
  • Chronic or recurrent urinary tract infections
  • Hypertension that has failed to respond to multiple forms of anti-hypertensive medication or could have a secondary cause
  • Electrolyte disorders or acid/base imbalance

The cause of any symptom can be found from important clues in the history and physical examination.  Laboratory tests are almost always aimed at:

·         urea,

·         creatinine,

·         electrolytes

·         urinalysis, which is frequently the key test in suggesting a diagnosis.

Other tests often performed by nephrologists are:

  • Renal biopsy, to obtain a tissue diagnosis of a disorder when the exact nature or stage remains uncertain
  • Ultrasound scanning of the urinary tract and occasionally examining the renal blood vessels
  • CT scanning when mass lesions are suspected or to help diagnosis nephrolithiasis;
  • Scintigraphy (nuclear medicine) for accurate measurement of renal function (rarely done), and MAG3 scans for diagnosis of renal artery disease or 'split function' of each kidney

Angiography or Magnetic resonance imaging angiography when the blood vessels might be affected
