A randomized controlled trial comparing transurethral resection of the prostate, contact laser prostatectomy and electrovaporization in men with benign prostatic hyperplasia: urodynamic effects.
J Urol. 2002 Sep; 168(3):1058-62.JU

Abstract

PURPOSE

We compared urodynamic and uroflowmetry improvements in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) after transurethral prostate resection, contact laser prostatectomy and electrovaporization.

MATERIALS AND METHODS

A prospective randomized controlled trial was performed in men with lower urinary tract symptoms suggestive of BPH who met the criteria of the International Scientific Committee on BPH, had a prostate volume of between 20 and 65 ml., and a Schäfer obstruction grade of 2 or greater. Before and 6 months after treatment urodynamics and free uroflowmetry were performed.

RESULTS

A total of 50, 45 and 46 men were randomized to transurethral prostate resection, laser treatment and electrovaporization, respectively. Baseline characteristics were similar in the 3 groups. Detrusor contractility did not change in any of the treatment groups. The average maximum free flow rate increased by a factor of 2.4 after transurethral prostate resection, 2.5 after laser prostatectomy and 2.4 after electrovaporization. The Schäfer obstruction grade decreased by a factor of 0.3 in all groups. Obstruction (Schäfer grade greater than 2) was not noted after transurethral prostate resection or electrovaporization but it was evident in 2 patients after laser prostatectomy. Effective capacity increased by a factor of 1.5 or more. The incidence of detrusor instability was decreased by half in all groups. The incidence of significant post-void residual urine volume decreased in all groups.

CONCLUSIONS

There were no significant differences in the improvement in urodynamic and uroflowmetry parameters 6 months after treatment when comparing transurethral prostate resection, contact laser prostatectomy and electrovaporization in men with lower urinary tract symptoms suggestive of BPH.
