This BackTable podcast is sponsored by Boston Scientific’s Urology Division. Boston Scientific is dedicated to transforming lives through innovative medical solutions that improve the health of patients around the world; this includes solutions for Benign Prostatic Hyperplasia or BPH, one of the most prevalent urologic conditions facing men today. [1,2]
Boston Scientific’s RezūmTM Water Vapor Therapy is a minimally invasive BPH treatment that provides urologists with an efficient, durable solution that reduces prostate volume while preserving sexual function. [3,4] With proven efficacy, durability, and lower clinical progression rates than daily medications, AUA guidelines support a shared decision-making process for the consideration of RezūmTM as a first-line treatment and alternative to medications. [3,5,6] Additionally, if insufficiently treated, BPH can negatively
impact bladder function, making earlier intervention valuable for patients. [7] Give your patients an alternative to daily medications and long-lasting BPH relief with Rezum Therapy.
