Pelvic muscle exercises are effective for mild stress urinary incontinence. A pressure transmission ratio of 80% or higher predicts successful outcomes in women undergoing Kegel exercises.

Area of Science:

  • Urology
  • Pelvic Floor Physical Therapy

Background:

  • Genuine stress urinary incontinence (SUI) affects many women.
  • Pelvic muscle exercises, like Kegel exercises, are a common conservative treatment for SUI.

Purpose of the Study:

  • To determine urodynamic predictors for the success of pelvic muscle exercises in women with genuine SUI.

Main Methods:

  • Thirty-six women with SUI underwent urodynamic studies before and after a 6-month Kegel exercise program.
  • Outcomes were assessed via subjective symptoms, objective urine loss, and pad count.
  • Receiver-operating characteristic (ROC) curve analysis evaluated the prognostic value of the pressure transmission ratio (PTR).

Main Results:

  • 56% of women showed significant improvement or cure after pelvic muscle training.

Related Experiment Videos

  • Improved patients demonstrated increased urethral closure pressure and significant changes in PTR during cough.
  • Mild SUI cases responded better than severe cases; a PTR of 80% or higher showed optimal predictive value.

    • Conclusions:

    • Kegel pelvic muscle exercises are more effective for women with mild SUI.
    • A pressure transmission ratio of 80% or greater is a positive prognostic indicator for treatment success in SUI.
