Studies investigating the incidence, risk factors, and outcomes of surgical-site hemorrhage after kidney transplantation are limited. Patients who underwent a kidney transplant from 1 January 2000 to 30 September 2012 (followed until 31 December 2012) at Toronto General Hospital were included in this study. Postoperative surgical-site hemorrhage was defined as a drop in hemoglobin 20 g/l over a 24-hour period within 3 days of transplantation, followed by an ultrasound indicating a significant hematoma/collection. A total of 59 of 1203 (4.9%) kidney transplant recipients had postoperative surgical-site hemorrhage. Most cases (89.8%) occurred within 1 day after transplantation. Living donor transplants [OR 0.30 (95% CI: 0.16, 0.55)] and higher recipient BMI [OR 0.54 per 10 kg/m(2) increase in BMI (95% CI: 0.30, 0.99)] were associated with a significantly lower risk of bleeding. Chronic preoperative anticoagulant usage led to an increased risk of bleeding but was not statistically significant [OR 1.75 (95% CI: 0.52, 5.88)]. Postoperative hemorrhage was associated with a higher risk of graft loss or death [HR 1.62 (95% CI: 1.01, 2.60)]. While the incidence of postoperative surgical-site hemorrhage in kidney transplantation is relatively low, it may be associated with an increased risk of graft loss or death.
