A new research headed by French scientists disclosed that matching up the weight of donors and recipients plays key role in kidney transplants.

During the research, scientists followed more than 1,000 transplant patients and detected that those having a small kidney in comparison to their weight were more prone to complications such as hypertension, kidney scarring, and around 55% increased risk of transplant failure two years after the operation.

In the Journal of the American Society of Nephrology, the study researchers said the discoveries would offer surgeons a new chance to improve long-term survival.

Professor Jean Paul Soulillou, from the French National Institute of Health and Medical Research, led the research.

Prof. Jean said that from a clinical point of view the impact of the finding was similar to when researchers identified markers to enable tissue type to be matched to reduce the risk of rejection.

"This information is potentially useful for thousands of transplants and provides a new opportunity to improve long-term graft survival," he added. (With Inputs from Agencies)
