Nephrology

Nephrology is the branch of internal medicine dealing with the study of the function and diseases of the kidney. The word nephrology is derived from the Greek word nephros, which means "kidney", and the suffix -ology, or "study of".

Scope of the specialty

Most diseases affecting the kidney are not limited to the organ itself, but are systemic disorders. Nephrology concerns itself with the diagnosis of kidney disease and its treatment (medication, dialysis), and follow-up of renal transplant patients. Additionally, most nephrologists consider themselves to be expert in the care of electrolyte disorders and hypertension. Given that most renal conditions are chronic, nephrologists "grow with their patients".

Who sees a nephrologist?

Patients are referred to nephrology specialists for various different reasons, such as :

Urologists are surgical specialists of the urinary tract. They are involved in renal diseases that might be amenable to surgery:

  • Diseases of the Bladder and prostate such as malignancy, stones, or obstruction of the urinary tract.

Diagnosis

As with the rest of medicine, important clues as to the cause of any symptom are gained in the history and physical examination.

Laboratory tests are almost always aimed at: urea, creatinine, electrolytes, and urinalysis-- which is frequently the key test in suggesting a diagnosis.

More specialized tests can be ordered to discover or link certain systemic diseases to kidney failure such as hepatitis b or hepatitis c, lupus serologies, paraproteinemias such as amyloidosis or multiple myeloma or various other systemic diseases that lead to kidney failure. Collection of a 24-hour sample of urine can give valuable information on the filtering capacity of the kidney and the amount of protein loss in some forms of kidney disease. However, 24-hour urine samples have recently, in the setting of chronic renal disease, been replaced by spot urine ratio of protein and creatinine.

Other tests often performed by nephrologists are:

Therapy

Many kidney diseases are treated with medication, such as steroids, DMARDs (disease-modifying antirheumatic drugs), antihypertensives (many kidney diseases feature hypertension). Often erythropoietin and vitamin D treatment is required to replace these two hormones, the production of which stagnates in chronic renal disease.

When symptoms of renal failure become too severe, dialysis might be required. Please refer to dialysis for a comprehensive account of this treatment.

If patients proceed to renal transplant, nephrologist often monitor the immunosuppressive regimen and the infections that can occur at this stage.
