Evolution of Bloodless Surgery: A Case for Bloodless Suprapubic Prostatectomy

Allogeneic blood transfusion is commonly prescribed to patients undergoing suprapubic prostatectomy for benign prostatic hyperplasia as a treatment option to replace blood loss. Historically, suprapubic prostatectomy has been perceived as an extremely high hemorrhagic surgery, and this has led to the association of suprapubic prostatectomy with a high rate of allogeneic blood transfusion. However, the outcome of suprapubic prostatectomy has significantly improved over the years and has become less hemorrhagic in many hands - creating the opportunity to consistently avoid allogeneic blood transfusion. On the other hand, the efficacy of blood transfusion has come under more stringent scrutiny as many clinical studies have reported inconsistent effects of blood transfusion on patient outcome. In contemporary practice, a more conservative/bloodless approach in the perioperative management of anemia in surgical patients is strongly being advocated with convincing evidence that many surgical patients can be routinely and safely managed without allogeneic blood transfusion. There is no large-scale discussion on bloodless surgery in urology in the contemporary literature, especially in the area of suprapubic prostatectomy that has been historically associated with a high rate of blood transfusion. This review article will discuss the evolution of bloodless surgery including the ongoing controversies surrounding blood transfusion in general, and then the relatively small but ongoing penetration of bloodless surgical approach in the field of suprapubic prostatectomy. Furthermore, the authors' approach to bloodless suprapubic prostatectomy will be highlighted, and in doing so, it can be emphasized that suprapubic prostatectomy is no more as hemorrhagic as was historically perceived, but rather a routine bloodless suprapubic prostatectomy is now possible in many hands.
