Predicting blood loss and transfusion requirements during radical prostatectomy: the significant negative impact of increasing body mass index.
Radical retropubic prostatectomy (RRP) has been associated with significant blood loss and/or transfusion requirement. While still a concern, routine autologous blood donation has not been standard at our institution for more than a decade. We assessed recent blood loss and transfusion requirements in contemporary patients undergoing RRP and examined the possible predictive impact of preoperative variables. ⋯ Our series demonstrates that blood loss during RRP continues to decrease. The respectable blood loss and low transfusion rates in this series were due to refinements in surgical technique rather than to perioperative modifications. To our knowledge the identification of BMI as a predictor of blood loss and transfusion is novel. These data serve as a benchmark for future comparisons and argue for continued refinements in techniques to decrease blood loss, particularly in overweight and obese patients.
