The two patients with failing kidneys each had willing living donors who were not compatible. Better matches were found, allowing the kidney exchange to take place last week at Vidant Medical Center.  The donors underwent their surgical procedure laproscopically, allowing their release from the hospital in two days. Their kidneys were given to Sherrie Hoopes of Jacksonville and Brenda Peele of Greenville. Both are off dialysis and are now enjoying normal kidney function. There were discharged at three and four days after surgery.
