We document changes in pressure-flow study parameters in patients treated by transurethral microwave thermotherapy.
Pressure-flow study tracings before and after therapy from 75 patients with benign prostatic hyperplasia were analyzed. Patients were stratified according to the predominant type of obstruction at screening (constrictive or obstructive).
An improvement in Madsen score and flow rates was noted at 6 months in both groups. In contrast to compressive obstruction patients, however, those with constrictive obstruction also showed significant changes in pressure-flow study parameters, including detrusor pressure at maximum flow, maximum flow rate and urethral resistance factor.
Patients with predominantly constrictive obstruction are the best candidates for microwave thermotherapy.
我们记录经尿道微波热疗治疗患者压力-流率研究参数的变化。
分析了75例良性前列腺增生患者治疗前后的压力-流率研究记录。患者根据筛查时主要梗阻类型（狭窄性或梗阻性）进行分层。
两组在6个月时均观察到马德森评分和流速有所改善。然而，与压迫性梗阻患者不同，狭窄性梗阻患者的压力-流率研究参数也有显著变化，包括最大尿流率时的逼尿肌压力、最大尿流率和尿道阻力因子。
以狭窄性梗阻为主的患者是微波热疗的最佳候选者。
