Hi, Thanks for writing in. Kidney transplant is a common surgery now and it is done in most cities. The transplanted kidney should be from a matching donor and this is a voluntary donation in India. Buying or selling kidneys is illegal. The const of the transplant is for surgery and recovery. This is around 3 to 5 lakhs Indian rupees. It can be higher if there is any problem. Please know that even after kidney transplant the person should be on long time medicines which will cost few thousands of rupees every month. The native kidneys are not disturbed during kidney transplant. The new kidney is put in the pelvis. Effectiveness of kidney transplant is based on many factors including primary cause of kidney failure, age of the patient, immunity and host graft rejection and the surgery. Many kidney transplants are successful on patients getting dialysis. Usually kidney transplant is done before 60 years of age. If patient is healthy then it can be done at 61 years of age after getting clearance from ethical board. Please do not worry.
