Transurethral water vapor ablation of the prostate with the Rezūm system: Urodynamic findings

The efficacy of the transurethral convective interstitial radiofrequency water vapour thermal ablation of the prostate with the Rezūm system for treating male lower urinary tract symptoms due to benign prostatic hyperplasia is well proven. The improvement of urodynamic parameters obtained from a simple uroflowmetry cannot measure the effect of water vapour injection on the bladder outlet obstruction. These data show that the possibility of significantly reducing the obstruction grade with even a single Rezūm procedure is concrete and seems to be independent of the degree of the obstruction grade.
