Area of Science:

  • Urology
  • Urodynamics
  • Pelvic Floor Disorders

Background:

  • Urethral instability is an emerging clinical diagnosis.
  • Understanding its prevalence and associations is crucial for managing lower urinary tract symptoms (LUTS).

Purpose of the Study:

  • To determine the prevalence of urethral instability in patients undergoing urodynamic assessment for LUTS.
  • To explore the relationship between urethral instability and detrusor instability.

Main Methods:

  • Urethral pressure profilometry was performed on 608 patients referred for urodynamic assessment.
  • Urethral instability was defined by a pressure variation of ≥15 cm water at the maximum urethral pressure (MUP).

Main Results:

  • Urethral instability was identified in 6.4% of the studied patients.

Related Experiment Videos

  • A significant association was observed between urethral instability and detrusor instability.
  • Frequency and urgency of micturition were linked to urethral instability.

    • Conclusions:

    • Urethral instability is a relevant finding in patients with LUTS.
    • It contributes to symptoms like urgency and frequency.
    • Presence of urethral instability elevates the risk of urinary incontinence.
