Renal function

Renal function refers to the functionality of the kidneys, which are responsible for filtering waste products, excess water, and other impurities from the blood. These waste products are stored in the bladder and later expelled from the body through urination.

Overview

The kidneys also regulate the body's levels of electrolytes, such as sodium, potassium, and phosphate, and they produce hormones that influence other bodily functions. For instance, the kidneys produce a hormone called erythropoietin, which stimulates the production of red blood cells.

Measurement of Renal Function

The Glomerular filtration rate (GFR) is the most commonly used indicator of renal function. It measures the volume of blood that the kidneys filter per minute. The GFR can be estimated (eGFR) from a serum creatinine measurement using the MDRD formula or the CKD-EPI formula.

Conditions Affecting Renal Function

Several conditions can affect renal function, including kidney disease, diabetes, and high blood pressure. These conditions can lead to chronic kidney disease (CKD), which can progress to end-stage renal disease (ESRD) if not properly managed.

Treatment of Renal Dysfunction

Treatment of renal dysfunction typically involves managing the underlying condition and may include medication, dietary changes, and in severe cases, dialysis or kidney transplant.
