Kidney Transplants: Many Discarded Kidneys Could Prolong Life
According to the Organ Procurement and Transplantation Network (OPTN), so far this year, 6,099 kidneys have been donated in the United States. Of these, living donors provided 2,223 kidneys, with the remaining 3,876 having been collected from deceased donors.
This means that around 13 people die each day without having received their kidney transplant.
When comparing the number of donated and discarded kidneys with that of the patients placed on the waiting list for transplantation, it becomes apparent that there is a severe shortage of organs.
High discard rates could be avoided
Dr. Sumit Mohan â€“ of the Columbia University College of Physicians and Surgeons and New York Presbyterian Hospital, both in New York City, NY â€“ and colleagues recently conducted a study on donated kidneys.
Dr. Mohan and colleagues worked with a sample of 975 kidneys, of which 427 came from living donors and 548 came from deceased donors.
The researchers note that the main reason for discarding donated organs in the U.S. is poor biopsy results. Their study analyzed the importance of these outcomes, considering whether, and to what extent, they influence the effectiveness of transplantations.
According to the data they collected throughout their study, it seems that the high discard rate of donated kidneys is unnecessary.
In the case of kidneys provided by living donors, it was found that biopsy results did not significantly affect patientsâ€™ health outcomes after transplantation. This might mean that most cases of discarded kidneys from living donors could be avoided in the future.
Transplants more effective than dialysis
The study also suggests that even kidneys that showed poor biopsy results, and which were collected from deceased donors, were more efficient in prolonging life expectancy than dialysis. The results indicated that even kidneys with the worst biopsy results could add an additional 5 years to a patientâ€™s life.
â€œ[â€¦] seventy-three percent of deceased donor kidneys with suboptimal biopsy results were still functioning at 5 years, suggesting that discards based on biopsy findings may be inappropriate and merits further study.â€

The research undertaken by Dr. Mohan and colleagues provides hope that high organ discard rates may drop in the future, allowing the high mortality rates of patients on the waiting list to decrease.
