Is night-time surgical procedure for renal graft at higher risk than during the day? A single center study cohort of 179 patients

Abstract

Introduction: Various surgical centers tend to postpone a kidney transplantation (KT) to the following morning than to operate at night-time. The objective of our study was to assess whether there was any difference between daytime and night-time renal transplantation in our institution. Method: This study is a retrospective monocentric study including all the KTs that were performed between 2012 and 2013 by transplant expert surgeons in our institution. Clavien-Dindo (CD) complications were classified according to 7 variables going from 1 to 5. Time before postgraft diuresis and delayed graft function (DGF) were also analyzed. Two groups of patients were formed according to threshold value of incision time (6.30 p.m.). Data comparison were performed using the Kruskal–Wallis nonparametric test. Results: A total of 179 patients were included. Median follow-up was 24 months. Cold ischemia time was longer in the night-time transplantation (1082 vs. 807 min, p
