Point-Counterpoint: HoLEP vs. GreenLightTM PVP–GreenLightTM PVP – Summary

Seth K. Bechis, MD, compares GreenLightTM photosensitive vaporization of the prostate (PVP) to holmium laser enucleation of the prostate (HoLEP,) illustrating how PVP can safely and effectively treat benign prostatic hyperplasia (BPH) in small and large prostates. Dr. Bechis first establishes BPH prevalence and expenses. He then cites American Urological Association (AUA) guidelines on the surgical management of BPH, noting that PVP may be used on small and average prostates. 

Dr. Bechis explains that large prostates are also good candidates for PVP, and PVP can offer an advantage for patients on anticoagulation. Dr. Bechis then emphasizes that 180-watt laser use contributes to properly, safely, and durably treating BPH and creating functional outcomes after two years, regardless of prostate size. He compares data between PVP outcomes on small and large prostates, reviewing differences in operative time, lasering time, and energy per unit volume of the prostate. He evaluates the similar data found between small and large prostates treated with PVP, including hospital stay, quality of life, and International Prostate Symptom Score (IPSS). 

Dr. Bechis then explores a 2017 study that found that PVP creates durable results at four years, provided that energy density remains at 3 KJ/cc or higher. Dr. Bechis also stresses that keeping the retreatment rate low for PVP depends on using the correct energy density. He continues by noting that there are fewer complications with PVP compared to HoLEP. Dr. Bechis completes his discussion by examining PVP’s relatively simpler learning curve and proficiency maintenance while also highlighting PVP as a financially sound option in BPH treatment. 

This lecture is part of a Point-Counterpoint debate. Its opposing lecture is “Point-Counterpoint: HoLEP vs. GreenLightTM PVP – HoLEP.”


About the 30th Annual Perspectives in Urology: Point Counterpoint conference: Presented by Program Chair and Grand Rounds in Urology Editor-in-Chief E. David Crawford, MD, this conference brought together leading experts in urology, medical oncology, and radiation oncology to discuss and debate the latest topics in genitourinary cancers, primarily prostate cancer and bladder cancer. This interactive conference offered topical lectures, pro/con debates, interesting-case presentations, interactive panel discussions, and interactive audience and faculty networking. 


Seth K. Bechis, MD is a board-certified urologist specializing in diseases of the urinary tract, including kidney stones, benign prostatic hyperplasia (BPH) or enlarged prostate, and men's health issues. Dr. Bechis completed fellowship training in laparoscopy/robotics and endourology at the University of California (UC), San Diego School of Medicine, and residency training at Harvard Medical School, Massachusetts General Hospital in Boston. He earned his medical degree from UC San Francisco School of Medicine and holds additional Master of Science training in biomedical research, also from UC San Francisco, focusing on ways to prevent and treat diseases.

As a member of the Comprehensive Kidney Stone Center at UC San Diego Health, Dr. Bechis has a special interest in advanced surgical treatment, medical prevention, and research on kidney stone disease. He has surgical expertise in percutaneous nephrolithotomy (PCNL) for complex stones, ureteroscopy, and shockwave lithotripsy. Dr. Bechis specializes in all procedures of the prostate including minimally invasive procedures such as Rezum water vapor therapy and UroLift, as well as robotic surgery and GreenLight™ Laser photoselective vaporization of the prostate (PVP).

Dr. Bechis serves as the associate program director for the UC San Diego - Kaiser Laparoscopy/Endourology Fellowship in the Department of Urology at UC San Diego School of Medicine. His current research includes improving surgical techniques and clinical outcomes in stone disease, as well as tools for stone diagnosis and opiate-sparing pathways for managing pain. His research has been featured in peer-reviewed medical journals and he has authored chapters for university handbooks.

Prior to joining UC San Diego Health, Dr. Bechis worked at Massachusetts General Hospital and Harvard Medical School, where he taught residents and medical students in the operating room and clinic.
