Abstract

Objective: To determine the usefulness of different urodynamic data and their relationship.

Methods: 105 adult males with prostatism were evaluated urodynamically. Data were obtained utilizing the Abrhams and Griffiths and the Schaeffer models.

Results: Our results show that the urinary flow rate correlates directly with bladder contractibility and inversely with the urethral resistance parameters.

Conclusions: 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.
