Water Vapor Thermal Therapy. How I Do It – Summary
Kevin C. Zorn, MD, FRCSC, FACS, analyzes water vapor thermal therapy for the treatment of benign prostatic hyperplasia (BPH), focusing on its application, benefits, and procedural techniques. His discussion highlights the efficacy and minimally invasive nature of this therapy, making it an appealing option for patients seeking relief from BPH symptoms.
Dr. Zorn explains the mechanism of water vapor thermal therapy, which involves the delivery of steam directly into the prostate tissue. He outlines the procedural steps, starting with patient preparation and anesthesia. Dr. Zorn details the insertion of the transurethral device and the precise delivery of water vapor to the targeted prostate zones.
The advantages of water vapor thermal therapy are discussed extensively. Dr. Zorn highlights its high safety profile, low risk of complications, and significant improvement in urinary symptoms and quality of life. He also notes the durability of the treatment outcomes. Challenges and potential complications are addressed, including transient dysuria, hematuria, and urinary retention.
Future directions for water vapor thermal therapy include ongoing research to refine techniques, improve patient outcomes, and expand the indications for this treatment. Dr. Zorn highlights the potential for combining this therapy with other minimally invasive treatments to enhance efficacy and broaden its applicability.

He is also an expert in performing surgery with the daVinciⓇSurgical Robotic System to manage localized prostate cancer and small renal masses.
Dr. Zorn attended McGill University in Montréal for his pre-med program, his medical degree, and his residency in Urological Surgery. He became a Fellow of the Royal College of Physicians and Surgeons of Canada (FRCSC) in 2005. Dr. Zorn also completed a fellowship in oncology and endourology at the University of Chicago. In 2007, he became certified by the American Board of Urology in urology and a Fellow of the American College of Surgeons.
Dr. Zorn was the first in Canada to use many new BPH technologies, including Greenlight XPS, Rezum, iTind, Optilume, Aquablation, and Zenflow. He has also been the first in Canada to introduce cutting-edge technologies, including the Clarius and ButterflyIQ point-of-care ultrasound (POCUS), as well as disposable AMBU4 cystoscopes for faster patient care and greater safety. Dr. Zorn is among the first physicians globally to be named as a Center of Excellence for Rezum and Greenlight vaporization and VIT (vapor incision technique). He is an international speaker and surgical trainer for these techniques.
Dr. Zorn is the senior author of theMale Lower Urinary Tract Symptoms (LUTS)/BPH Guidelinesfor the 2018 and 2022 Canadian Urological Association (CUA) and consulted on the American Urological Association BPH guidelines. He has also helped create national online programs in robotic prostate cancer care and rehabilitation, as well as the CUA BPH patient decision-aid tool. Dr. Zorn has authored 400 peer-reviewed publications and 12 book chapters on BPH and minimally invasive surgical care.
