As per protocol, patients who require cadaver organs are put in the waiting list. But in India, number of patients requiring organs are more as compared to number of organs available.
There are two types of waiting list; one is urgent waiting list and another one is regular waiting list. Urgent listing of patients for cadaver organ transplant is primarily based on medical criteria, i.e. patient needs organ on urgent basis otherwise he/she may not survive.
Regular waiting list is also based on medical criteria and these criteria are different for different organs. Like for kidney transplant, main criteria is time spent on regular dialysis. Similarly, for other organs, criteria are different.
