GreenLight HPS™ 120-W laser vaporization vs transurethral resection of the prostate (less than 60 mL): A 2-year randomized double-blind prospective urodynamic investigation, "Beyond the Abstract," by João Antonio Pereira-Correia, MD, MSc

BERKELEY, CA (UroToday.com) - Our medium-term (urodynamic findings) demonstrate, for the first time, the satisfactory performance of TURP and Green Light HPS™ 120-W PVP in restoring the vesical function in cases of bladder outlet obstruction caused by benign prostatic enlargement.

Twenty men with BPH and medium to severe refractory lower urinary tract symptoms (LUTS) were randomly assigned to undergo TURP or PVP. The men did not know which treatment they received. Repeatedly over 24-months after surgery, they returned for evaluation by 2 urologists and a neuro-urologist; these 3 doctors were also unaware of patients' study assignments.

Both groups had improvements in infravesical obstruction, with a significant reduction of at least 20 cm H2O in mean micturition pressure.

Although very well designed, our study was performed with a small number of patients. We have no doubt that further studies on this topic are needed, and we hope that our findings will encourage further detailed analyses of long-term vesical function related to prostatic photovaporization.
