Is There a Role for Preoperative 5 Alpha Reductase Inhibitors in Reducing Prostate Vascularity and Blood Loss?

Benign prostatic hyperplasia (BPH) and the related medical problems are a major burden as health care costs and as a cause of patient morbidity. The introduction of medical therapy largely offered an alternative to surgical therapy, and these medications have been linked with multiple positive BPH-related outcomes. With ubiquitous use, however, a variety of adverse side effects and unsupported claims to these medications have been reported both in scientific literature and popular press. The use of 5 alpha reductase inhibitors (5ARIs) to reduce recurrent bleeding due to BPH is a reasonable option for men with recurrent trips to the physician or hospital. After a largely anecdotal report of their use in the preoperative period to reduce bleeding during BPH surgery, there was interest in the use of 5ARIs for this indication considering the effusive bleeding that can occur during BPH-related surgery, a dreaded and not uncommon complication. While the pathophysiology for the use of 5ARI to reduce BPH-related bleeding is sound, the actual clinical outcomes still require scrutiny to determine if the efficacy is both scientifically valid and clinically significant. This report will review the current literature on this topic and make attempts to determine if the use of a 5ARI before BPH-related surgery should be encouraged.
