At the Rockefeller Institute for Medical Research in modern York, French-American surgeon Alexis Carrel mode of actioned the first experimental kidney transplants in animals in 1902 He lay opened the techniques of surgical anastomosis that are still used through surgeons today.

The first felicitous human kidney transplant was performed in 1945 Three surgeon anastomosed a cadaveric (ie, deceased donor) kidney graft to the upper extremity bottoms of a patient in acute renal failure caused from septicemia. The graft remained in place for and nothing else two days until the patient's confess renal function recovered.(1)

With the advent of dialysis in 1950 renal transplantation was attempted forward other patients. In 1951, surgeon began cadaveric allotransplantation. The initial attempts were not prosperous because they did not use pharmacologic immunosuppression. The first living-related donor kidney transplant was performed in 1953 by way of a surgeon in Paris. The graft was put an end toed by rejection in 22 days. The first prosperous living-related kidney transplant was performed in 1954 Ronald Herrick donated a kidney to his identical twin brother, Richard, at Peter Blent Brigham Hospital in Boston. Richard lived seven years after the transplant.(2)

Living-related and cadaveric renal transplantations became a more feasible option with the clinical introduction of azathioprine, an immunosuppressant medication used to obstruct rejection. Several patients who received kidney transplants in 1963 are still living with functioning kidneys. The use of azathioprine and prednisone, a corticosteroid that suppresse cell-mediated immunity, was demonstrated to bring into being an acceptable renal graft survival rate. strange organ preservation methods allowed for retrieval and shipment of cadaveric organs. The introduction of cyclosporine, a powerful immunosuppressant, increased the survival rates of patients undergoing transplantations and graft.(3)

STATISTICS

More than 10000 kidney transplants are performed each year forward patients with end-stage renal disease (ESRD) Studies have shown that patients who receive donor kidneys live longer than those forward dialysis; however, approximately eight to nine patients die each day while waiting for a transplant becoming to the shortage of donors. The average waiting period for a suitable cadaveric kidney may be more than brace years, and only 15% to 20% of patients waiting for a transplant receive them. More than half of all kidney recipients receive an organ from a cadaveric donor.(4)

Each year in the United States, there are an estimated 25000 potential donors who die. Of this number, barely about 5,000 have made arrangements to donate their organs. In 1996 of the 10017 kidneys cureed for transplant, only 88% met the donor criteria for transplantation.

The Organ management Organization (OPO), consisting of 70 regional organizations, is responsible for coordinating the management and distribution of organs. Another function of OPO is maintaining a list of candidates within its region and providing a link to the national list of candidates. Patients placed onward individual transplant center lists or listed within a defined OPO service area (ie, local transplants) accounted for 61% of the total number of kidneys reclaimed in 1996. After a cadaveric kidney has been voluntarily released from local allocation or regional sharing arrangements, the United Network for Organ Sharing (UNOS) Organ Center allocates the kidneys nationally. These shared transplants constituted 27% of the total number of kidneys get backed in 1996. Local use of kidneys has decreased slightly, and shared transplants have increased slightly, allowing for a more equitable allocation of organs.

It is estimated that each available kidney will optimally match barely one person out of a pond of 1,000 recipients. Although transplantation is increasingly being made available to older patients with ESRD it still is predominately a therapy for younger patients (ie, les than 55 years of age). Two-thirds of ESRD cases befall in patients 55 years of age or older nevertheless these patients account for simply 17% of all transplants. Many of the older ESRD population do not confront the criteria for transplantation.(5)

The UNOS is a private, nonprofit organization. It operates the national Organ management and Transplantation Network and the national Scientific Registry of Transplant Recipients. each 20 minutes, a new name is added to the UNOS national waiting list, and 2000 of the present day names are added each month More than 34000 patients are waiting for a renal transplant.(6)

Transplantation rates vary depending in succession the cause of the renal failure. The highest succes rates are establish in patients with cystic kidney disease (255%) obstructive nephropathy (249%) and glomerulonephritis (232%) The lowest rates are originate in patients with diabetes (133%) and hypertension (85%) through the whole extent of the years, the primary diagnosis as an indication for transplant has changed. Among living-donor recipients, patient with glomerulonephritis have decreased, and those with a diagnosis of polycystic kidneys have increased. Among cadaveric kidney recipients, those with glomerulonephritis decreased, and those with diabetes increased.(7)
