This study explores the use of non-heart beating donors for renal transplantation, including the selection criteria, outcomes, and biopsy results. The findings suggest that while there may be higher rates of primary non-function and delayed graft function, graft survival rates at 5 years are comparable to other donors. Biopsy can help distinguish between primary non-function and delayed graft function but should be used with caution.

Sources of asystolic donors in Leicester • Irreversible cardiorespiratory arrest • Accident & Emergency department –failed resuscitation after MI • Medical wards –catastrophic intracerebral haemorrhage with ‘coning’
Leicester selection criteria for NHBDs • Age<60 • Warm ischaemic time <40 minutes • No history of renal impairment • No uncontrolled hypertension • No complicated insulin dependent diabetes • No systemic sepsis or malignancy

Conclusions: Non-heart beating donor kidneys • Increased PNF rate (decreases with experience) • High DGF rate; dialysis usually needed • Slightly higher serum creatinine, may compensate • Slightly more interstitial fibrosis at 6 months • Indistinguishable graft survival rate at 5 years • Biopsy does not help with donor selection (?) • Protocol biopsies detect acute rejection at unchanged rate • Biopsy helps to distinguish PNF and DGF, but care needed
