Mp70-06 Blood Transfusion and Timing Following Open and Minimally Invasive Nephrectomy

Abstract

Thirty-day mortality was 3 times higher in the OC cohort, 1.7% versus 0.6% in the overall nephrectomy cohort. 8 deaths were observed; all underwent radical nephrectomy or nephroureterectomy for malignancy. 7 of the 8 patients who died were male (88%). Of those, median blood loss was higher (2-5 litres) and operating time was over 3 hours in all cases.CONCLUSIONS: When OC occurs, patients experience poorer clinical outcomes with respect to blood loss, post-operative morbidity, and length of stay. Risk factors predictive of OC include bleeding, nephrectomy for malignancy and tumour size (>7cm). When combined with male sex, blood loss (>2 litres) and prolonged operation times (> 3 hours) OC is associated with increased risk of death.
