Potassium titanyl phosphate laser prostatectomy: a review

Purpose of review High-powered potassium titanyl phosphate laser (GreenLight PV) has gained attention as a minimal access alternative for the treatment of prostate obstruction. This article reviews the recent data and technical refinements of potassium titanyl phosphate laser prostatectomy. Recent findings The technique is similar to transurethral resection of the prostate in improving symptoms and urinary flow but with minimal morbidity. Striking advantages of this technique include minimal catheter times, true day-case surgery and the virtual abolition of blood transfusions. The absence of intraoperative irrigant absorption (transurethral resection syndrome) in this technique allows high-risk patients, or those with massive prostates, to be safely treated with minimal hospitalization. Summary The availability of a safe and effective technique to overcome the considerable drawbacks of open prostatectomy and transurethral resection of the prostate is a major advance. Although randomized studies are limited, multicentre prospective data from a variety of clinical settings show similar benefits and promising durability over 3-5 years.
