A case of kidney transplantation using donation after circulatory death with renal calculi.

ABSTRACT: Donation after circulatory death (DCD) supplies a big percentage of the organ source pool. Compared to living-related donations, donor kidneys from DCD are commonly with lower quality since they inevitably suffer from hypoxia, hypotension, and inadequate organ perfusion during the progression to circulatory arrest. The current case presents a 44-year-old male donor with wide range subarachnoid hemorrhage and multiple skull fracture from a car accident. Multiple stones were detected in his right kidney. We performed a modified ex vivo pyelolithotomy and ureteroscopy on the bench to render a stone-free allograft. We also improved the donor kidney with hypothermic/perfusion preservation machine before renal transplantation. The recipient showed no complications during the first two-month post-operational follow-up. Such a donor kidney with stones may probably be discarded by conventional perspective. Yet, the combination of the ex vivo bench-surgery technique and hypothermic oxygenation/perfusion makes it a qualified donor kidney. Thus we have demonstrated a promising way of saving borderline qualified DCD donor kidneys.

Project description:Background and objectivesThe broader use of combined expanded criteria donor and donation after circulatory death (ECD/DCD) kidneys may help expand the deceased donor pool. The purpose of our study was to evaluate discard rates of kidneys from ECD/DCD donors and factors associated with discard.Design, setting, participants, & measurementsECD/DCD donors and kidneys were evaluated from January 1, 2000 to March 31, 2011 using data from the Scientific Registry of Transplant Recipients. The kidney donor risk index was calculated for all ECD/DCD kidneys. Multivariable logistic regression models were used to determine risk factors for discarding both donor kidneys. The Kaplan-Meier product limit method and the log-rank statistic were used to assess the cumulative probability of graft failure for transplants from ECD/DCD donors where the mate kidney was discarded versus both kidneys were used.ResultsThere were 896 ECD/DCD donors comprising 1792 kidneys. Both kidneys were discarded in 44.5% of donors, whereas 51.0% of all available kidneys were discarded. The kidney donor risk index scores were higher among donors of discarded versus transplanted kidneys (median, 1.82; interquartile range, 1.60, 2.07 versus median, 1.67; interquartile range, 1.49, 1.87, respectively; P<0.001); however, the distributions showed considerable overlap. The adjusted odds ratios for discard were higher among donors who were older, diabetic, AB blood type, and hepatitis C positive. The cumulative probabilities of total graft failure at 1, 3, and 5 years were 17.3%, 36.5%, and 55.4% versus 13.8%, 24.7%, and 40.5% among kidneys from donors where only one versus both kidneys were transplanted, respectively (log rank P=0.04).ConclusionsOur study shows a significantly higher discard rate for ECD/DCD kidneys versus prior reports. Some discarded ECD/DCD kidneys may be acceptable for transplantation. Additional studies are needed to evaluate the factors that influence decision making around the use of ECD/DCD kidneys.
