This review provides an update on the treatment of benign prostatic hyperplasia and the pharmacologic considerations for perioperative care. By age 85 years, approximately 90% of men have prostate histologic characteristics consistent with benign prostatic hyperplasia. Pharmacologic treatment with an alpha1 receptor antagonist may reduce symptoms and, when given in combination with a 5-alpha-reductase inhibitor, may decrease the risk of urinary retention and the need for surgical intervention. Transurethral resection of the prostate has been the historical standard when surgical intervention is indicated. However, recent evidence suggests that Holmium laser enucleation of the prostate may have similar efficacy with less risk of complications and with decreased catheterization time. Prostatic urological operations may have perioperative complications, including urethral bleeding, acute urinary retention, urinary tract infection, urge incontinence, and venous thromboembolism. Pharmacist recommendations for the appropriate use of laxatives, antibiotics, anticoagulation, and urinary antispasmodics are key components of perioperative management. Surgical interventions improve symptoms but may have complications, providing the pharmacist an opportunity to improve perioperative care.
