Renal or kidney transplantation, is a surgery which involve implantation of a healthy donor kidney to a patient suffering from an end-stage renal disease (ESRD).
There are two types of donors:
On the other hand, the kidney taken from a deceased donor is called deceased donor kidney, and patients must get their names listed on the waiting list to get the chance for the transplant.
Renal transplantation is the definitive treatment for patients with end stage renal disease (ESRD). ESRD can be defined as patients who are suffering with chronic kidney disease (CKD) and require regular dialysis or possibility of permanent dialysis requirement is imminent.
Before transplant surgery, donor and recipient have to undergo certain investigations related to fitness for surgery, matching of kidney and proof of relationship. Donor is evaluated whether he / she is fit for donation and not suffering with any disease which can impact his life after donation. Better one of his two kidneys, is left with donor. Certain legal formalities have to be done for approval of transplantation by committee. The other hand, in cadaveric donation, two to three blood group matched ESRD patients are called as per waitlist, as and when cadaveric kidney is available for transplantation. They are prepared for transplantation and one who has best cross match with donor kidney receive the kidney graft.
During the renal transplant procedure, the surgeon makes an incision on one side of lower abdomen, and the donor kidney is placed in abdomen. The blood vessels of the donor kidney are connected to the arteries and veins of the patient. The ureter of the donor kidney is also connected with the bladder of the patient. A siliconized stent is placed inside donor kidney to patient urinary bladder which is usually removed two weeks after surgery by simple procedure of flexible cystoscopy. A urinary catheter and drainage tube are also placed which are removed before discharge from hospital. Abdominal incision is closed by fine suture or staples. Patient is usually kept for 7 days is hospital. Donor kidney is removed by laparoscopy usually which involve 3-4 small holes and one small lower abdominal cut to remove kidney. Donor is usually discharged from hospital after 4 days of surgery.
The patient usually makes lot of urine in tune of half to one liter per hour which usually sets to 2-3 liter per day after 5-7 days of surgery. His creatinine improved to normal. Immunosuppressant drugs are given and monitored as per their level in blood. Even after getting discharged, the patient needs to visit the hospital for regular checkups initially twice a week for a month and weekly for next month. He has to continue immunosuppressant medication for life.
Renal transplantation is one of the best ways to treat the patient suffering from the end-stage renal disease. Below are some of the advantages of a renal transplant:
TJust like every transplant, renal transplant is also associated with some of the risks and complications that can occur after the renal transplant procedure. Some of the complications a patient may experience after a renal transplant are rejection of the donor kidney, infection, bleeding, failure of the donor kidney and reaction to medications. Regular follow up and investigations are required for early diagnosis and treatment of any of these complications.
