Urodynamic evaluation in men with prostatism reveals that urinary flow rate is linked to bladder contractility and urethral resistance. Urethral resistance involves factors affecting voiding initiation and maintenance.

Area of Science:

  • Urology
  • Medical Engineering

Context:

  • Prostatism affects adult males, necessitating detailed urodynamic evaluation.
  • Understanding the interplay of urodynamic parameters is crucial for managing lower urinary tract symptoms.

Purpose:

  • To assess the utility and interrelationships of various urodynamic data in men with prostatism.
  • To elucidate the factors contributing to urethral resistance and bladder contractility.

Summary:

  • Urodynamic testing in 105 males with prostatism utilized Abrhams and Griffiths and Schaeffer models.
  • Results indicate a direct correlation between urinary flow rate and bladder contractility.
  • Urinary flow rate showed an inverse relationship with urethral resistance parameters.

Impact:

  • Identifies two independent factors contributing to urethral resistance: one affecting voiding initiation (opening pressure) and another affecting voiding maintenance (PURR curvature/slope).
  • Establishes a relationship between bladder contractility and pressure at maximum flow rate.
  • Provides a foundation for more precise diagnosis and targeted treatment of prostatism.
