Spinal Fluid Leaks. The spinal cord and nerves are covered by a protective watertight sac of tissue (dura mater). During a spinal surgery, it is not uncommon for a rupture or tear to occur in this dura mater. If this happens, spinal fluid will begin to leak. If the tear is noticed during the surgery, it is repaired and usually heals uneventfully. If a tear occurs and is not noticed, the tear may heal on its own.
1 The cost benefit of kidney transplantation compared to dialysis over a period of ten years (the median transplant survival time) is Â£241,000 or Â£24,100 per year for each year that the patient has a functioning transplanted kidney.  In 2008-09, 2,497 people received a kidney transplant.
Organ procurement is a surgical procedure that removes organs or tissues for reuse, typically for organ transplantation. It is heavily regulated by United Network for Organ Sharing to prevent unethical allocation of organs. There are over 110,000 patients on the national waiting list for organ transplantation and in 2016, only about 33,000 organ transplants were performed. Due to the lack of organ availability, about 20 patients die each day on the waiting list for organs. Organ transplantation and allocation is mired in ethical debate because of this limited availability of organs for transplant. In the United States in 2016, there were 19,057 kidney transplants, 7,841 liver transplants, 3,191 heart transplants, and 2,327 lung transplants performed.
