We studied 34 patients with benign prostatic hypertrophy who had infravesical obstruction with a high opening pressure and a stable bladder. No treatment was given except for intermittent short courses of plant extracts. There were no factors other than prostatic obstruction that could affect the mechanics of micturition. The patients were reassessed after a mean of 21 months (range 7 to 62). Voiding dynamics were unchanged in 12 patients who had a stable obstructed bladder, while 22 had an unstable obstructed bladder with a significantly greater opening pressure. Peak flow pressure was also increased but much less so that at the onset of voiding. The driving pressure and bladder volume were decreased. Despite this fact, urine flow rates were unchanged and maximum external voiding power was enhanced. The significance of such findings is discussed.
我们研究了34例良性前列腺增生患者，这些患者存在膀胱颈下梗阻，开放压高且膀胱稳定。除了间歇性短期使用植物提取物外，未给予其他治疗。除前列腺梗阻外，没有其他因素会影响排尿机制。平均21个月（范围7至62个月）后对患者进行了重新评估。12例膀胱梗阻稳定的患者排尿动力学未改变，而22例膀胱梗阻不稳定，开放压明显更高。排尿高峰压力也有所增加，但远低于排尿开始时。驱动压力和膀胱容量降低。尽管如此，尿流率未改变，最大外部排尿力增强。讨论了这些发现的意义。
