Nephrology is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function and kidney disease, the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal replacement therapy. The word "renal" is an adjective meaning "relating to the kidneys", and its roots are French or late Latin. Whereas according to some opinions, "renal" and "nephro" should be replaced with "kidney" in scientific writings such as "kidney medicine" or "kidney replacement therapy", other experts have advocated preserving the use of renal and nephro as appropriate including in "nephrology" and "renal replacement therapy", respectively.
Kidney dialysis is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. Along with kidney transplantation, it is a type of renal replacement therapy.
Kidney failure, also known as end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney failure, which develops slowly and can often be irreversible. Symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications of acute and chronic failure include uremia, hyperkalemia, and volume overload. Complications of chronic failure also include heart disease, high blood pressure, and anaemia.
Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function occurs over a period of months to years, or abnormal kidney structure. Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications can relate to hormonal dysfunction of the kidneys and include high blood pressure, bone disease, and anemia. Additionally CKD patients have markedly increased cardiovascular complications with increased risks of death and hospitalization. CKD can lead to kidney failure requiring kidney dialysis or kidney transplantation.
Peritoneal dialysis (PD) is a type of dialysis that uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood. It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure. Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years. Other benefits include greater flexibility and better tolerability in those with significant heart disease.
Kidney transplant or renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD). Kidney transplant is typically classified as deceased-donor or living-donor transplantation depending on the source of the donor organ. Living-donor kidney transplants are further characterized as genetically related (living-related) or non-related (living-unrelated) transplants, depending on whether a biological relationship exists between the donor and recipient. The first successful kidney transplant was performed in 1954 by a team including Joseph Murray, the recipient's surgeon, and Hartwell Harrison, surgeon for the donor. Murray was awarded a Nobel Prize in Physiology or Medicine in 1990 for this and other work. In 2018, an estimated 95,479 kidney transplants were performed worldwide, 36% of which came from living donors.
In medicine, Kt/V is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy.

Artificial kidney is often a synonym for hemodialyzer, but may also refer to the other renal replacement therapies that are in use and/or in development. This article deals mainly with bio-artificial kidneys featuring cells that are grown from renal cell lines/renal tissue.
The National Kidney Foundation, Inc. (NKF) is a voluntary nonprofit health organization in the United States, headquartered in New York City, with over 30 local offices across the country. Its mission is to prevent kidney and urinary tract diseases, improve the health and well-being of individuals and families affected by these diseases, and increase the availability of all organs for transplantation. NKF is the largest, most comprehensive, and longstanding patient-centric organization dedicated to the awareness, preventions and treatments of kidney disease in the United States.
The National Kidney Foundation Singapore scandal, also known as the NKF saga, NKF scandal, or NKF controversy, was a July 2005 scandal involving National Kidney Foundation Singapore (NKF) following the collapse of a defamation trial which it brought against Susan Long and Singapore Press Holdings (SPH). This sparked significant controversy, causing a massive backlash and fallout of donors to the charity; it then subsequently resulted in the resignation of chief executive officer T.T Durai and its board of directors.
Northwest Kidney Centers is a regional, not-for-profit community-based provider of kidney dialysis, public health education, and research into the causes and treatments of chronic kidney disease. Established in Seattle in 1962, it was the world's first out-of-hospital dialysis provider. It offers dialysis throughout the greater Seattle area in 20 free-standing clinics, eight hospitals and its home dialysis program. It opened its first clinic in Everett in 2020, the organization's first in Snohomish county.

Life Is Beautiful is a Singaporean Chinese drama produced by MediaCorp Channel 8. The drama is a collaboration between MediaCorp and the National Kidney Foundation (NKF), which hopes to raise awareness of kidney-related diseases.
David Wayne Johnson is an Australian nephrologist known for kidney treatments and transplants in Australia. In 2009 he was a Queensland State Finalist for Australian of the Year, for his work in the early recognition and care of people with chronic kidney disease and specifically for his work in detection of chronic kidney disease.
Epstein syndrome is a rare genetic disease characterized by a mutation in the MYH9 gene in nonmuscle myosin. This disease affects the patient's renal system and can result in kidney failure. Epstein syndrome was first discovered in 1972 when two families had similar symptoms to Alport syndrome. Epstein syndrome and other Alport-like disorders were seen to be caused by mutations in the MYH9 gene, however, Epstein syndrome differs as it was more specifically linked to a mutation on the R702 codon on the MYH9 gene. Diseases with mutations on the MYH9 gene also include May–Hegglin anomaly, Sebastian syndrome and Fechtner syndrome.
The SIA-NKF Dialysis Centre is a dialysis centre in Toa Payoh, Singapore, and was the first dialysis centre outside of a hospital in Singapore.
