Abstract

Purpose: We evaluated the urodynamic changes after high energy microwave thermotherapy in patients with lower urinary tract symptoms and benign prostatic enlargement.

Materials and methods: A total of 120 patients was available for analysis with urodynamic investigation and pressure-flow studies before and 6 months after treatment. Several obstruction parameters were used to evaluate treatment outcome.

Results: A significant decrease (p < 0.001) in all obstruction parameters was noted. Mean detrusor pressure at maximum flow decreased from 64.7 to 39.1 cm. water, urethral resistance factor from 41.8 to 23.5 cm. water and linear passive urethral resistance relation from 3.0 to 1.4. Analysis of subgroups showed better results in patients with greater degrees of obstruction.

Conclusions: High energy thermotherapy results in a significant and substantial decrease in bladder outlet obstruction.
