To determine the usefulness of different urodynamic data and their relationship.
105 adult males with prostatism were evaluated urodynamically. Data were obtained utilizing the Abrhams and Griffiths and the Schaeffer models.
Our results show that the urinary flow rate correlates directly with bladder contractibility and inversely with the urethral resistance parameters.
The urethral resistance was produced by two independent factors: a factor which resists initiation of voiding, measured by the opening pressure according to the Schaeffer model; a second factor which opposes maintenance of voiding, measured by the PURR curvature of the Schaeffer model and by the slope of the Abrhams and Griffiths model. Bladder contractibility was related to pressure at maximum flow rate of the Schaeffer model.
确定不同尿动力学数据的实用性及其相互关系。
对105名患有前列腺增生症的成年男性进行尿动力学评估。使用亚伯拉罕斯和格里菲斯模型以及谢弗模型获取数据。
我们的结果表明，尿流率与膀胱收缩力直接相关，与尿道阻力参数呈负相关。
尿道阻力由两个独立因素产生：一个是抵抗排尿起始的因素，通过谢弗模型的开放压测量；另一个是阻碍排尿维持的因素，通过谢弗模型的PURR曲率以及亚伯拉罕斯和格里菲斯模型的斜率测量。膀胱收缩力与谢弗模型最大尿流率时的压力相关。
