A urodynamic study was done to judge the capability of laser treatment to relieve bladder outlet obstruction.
Advanced urodynamic studies with pressure-flow analysis were performed before and 6 months after laser treatment using 3 different laser devices.
Forty patients showed significant improvement in all obstruction parameters (detrusor pressure at maximum flow rate, urethral resistance relation, theoretical cross-sectional urethral area, minimal detrusor pressure and linear passive urethral resistance relation) together with significant subjective improvement in international prostate symptom score. After treatment 82 to 92% of the patients could no longer be considered to have obstruction. No difference in outcome among the devices used was found.
Laser prostatectomy is indeed capable of relieving bladder outlet obstruction.
进行尿动力学研究以判断激光治疗缓解膀胱出口梗阻的能力。
使用3种不同的激光设备，在激光治疗前及治疗后6个月进行压力 - 流分析的高级尿动力学研究。
40例患者在所有梗阻参数（最大尿流率时的逼尿肌压力、尿道阻力关系、理论尿道横截面积、最小逼尿肌压力和线性被动尿道阻力关系）方面均有显著改善，国际前列腺症状评分也有显著的主观改善。治疗后，82%至92%的患者不再被认为存在梗阻。所使用的设备在治疗效果上未发现差异。
激光前列腺切除术确实能够缓解膀胱出口梗阻。
