ISLAMABAD: The results of a new study suggest that high discard rates among donated kidneys could be avoided in the future. Researchers say that even kidneys with poor biopsy results may be more efficient in prolonging patients' lifespans than other treatments.

Dr. Sumit Mohan - of the Columbia University College of Physicians and Surgeons and New York Presbyterian Hospital, both in New York City, NY - and colleagues recently conducted a study on donated kidneys.

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 patients' health outcomes after transplantation. This might mean that most cases of discarded kidneys from living donors could be avoided in the future.
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 patient's life.

Dr. Sumit Mohan said that "[...] 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."
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.
