Pre-Implantation trial of Histopathology in renal Allografts

Chief investigator: Mr Gavin Pettigrew
Primary sponsor: Cambridge University Hospitals
Funder: NIHR Research for Patient benefit


Does the introduction of a national, pre-implantation biopsy histopathology service increase numbers and improve outcomes of kidney transplants performed in the UK?

Study hypothesis

Provision of a national, 24/7 pre-implantation biopsy service results - at reasonable cost - in the transplantation of a greater proportion of kidneys offered from ECD donors, and/or improves kidney transplant function at one year post-transplant.

Numbers of deceased donor kidney transplants performed annually in the UK are consequently significantly increased or improved in quality.

Study design

An open, stepped-wedge cluster, randomised trial.
