PRESSURE-FLOW STUDY ANALYSES IN PATIENTS TREATED WITH HIGH-ENERGY THERMOTHERAPY

Purpose: We evaluated the urodynamic changes after high energy microwa ve thermotherapy in patients with lower urinary tract symptoms and ben ign prostatic enlargement. Materials and Methods: A total of 120 patie nts was available for analysis with urodynamic investigation and press ure-flow studies before and 6 months after treatment. Several obstruct ion parameters were used to evaluate treatment outcome. Results: A sig nificant 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 li near passive urethral resistance relation from 3.0 to 1.4. Analysis of subgroups showed better results in patients with greater degrees of o bstruction. Conclusions: High energy thermotherapy results in a signif icant and substantial decrease in bladder outlet obstruction.
