Photoselective vaporization of the prostate (PVP) is an alternate method that is challenging traditional transurethral resection of the prostate (TURP) because of its lesser morbidity. PVP is when a laser vaporizes the prostate tissue and coagulates it at he same time. This is possible because of the wavelength of the laser at 532-nm which travels through the fluid medium and is absorbed by hemoglobin in cells. The prostate tissue turns into gas by way of the laser energy and is vaporized. This study is a systematic review of 9 randomised trials which have compared head-to-head these 2 techniques – PVP v TURP between 2002 – 2012. The results are promising in favor of PVP, either using the 80-W or 120-W systems:
This is a very important topic because BPH affects 60% of men at 70-80 years old. Also TURP has been associated with morbidity such as bleeding and TUR syndrome, and has a retreatment rate of 5-15% at 5 years.
