Vaporization of the prostate

Purpose of review Transurethral resection of the prostate remains the treatment of choice for men with symptomatic benign prostatic enlargement. Concerns regarding the morbidity of this operation have led to the development of alternative surgical procedures. Vaporization of the prostate can be achieved using either laser energy or electrosurgery. The advantage of these approaches is that they allow tissue removal with reduced blood loss. Vaporization techniques have been around for almost a decade and more powerful lasers have recently become available. This has led to a minor resurgence in interest in laser vaporization. We reviewed articles on all forms of vaporization of the prostate published in the 12 months from August 2002. Recent findings Electrovaporization of the prostate is an effective treatment for men who require surgery for benign prostatic enlargement. The results are well maintained at 5 years follow-up with low reoperation rates. Scanty data are available for the Gyrus (Gyrus Medical Ltd, Cardiff, Wales) bipolar electrovaporization system but preliminary results suggest there is no significant advantage over transurethral resection of the prostate. Early forms of laser vaporization of the prostate are not as effective as either transurethral resection of the prostate or transurethral electrovaporization of the prostate and have a higher. retreatment rate. Newer, more powerful lasers have been recently introduced with encouraging initial results in small numbers of patients. Summary Electrovaporization of the prostate is a safe, effective and durable alternative to transurethral resection. Early laser vaporization techniques have high retreatment rates, which limit their cost-effectiveness. Few data are yet available on high-powered lasers for bladder outflow obstruction. Whether any vaporization technique will stand the test of time is unclear.
