An objective noninvasive procedure has been developed to evaluate the urodynamics of benign prostatic hypertrophy. The test uses pneumatic occlusive cuffs similar to those used for blood pressure measurements and the electrical engineering concepts of open-circuit, short-circuit, and transient response measurements. The cuff is first inflated to measure pressure, then rapidly released, yielding the transient response and subsequent unimpeded flow. From the pressure and flowrate recordings as functions of time, objective evaluations of bladder strength and urethral obstruction are extracted.
一种客观的非侵入性程序已被开发出来，用于评估良性前列腺增生的尿动力学。该测试使用类似于用于血压测量的气动闭塞袖带，以及开路、短路和瞬态响应测量的电气工程概念。首先给袖带充气以测量压力，然后迅速释放，产生瞬态响应和随后的无阻流动。从作为时间函数的压力和流量记录中，提取对膀胱强度和尿道梗阻的客观评估。
