Summary

Pelvic floor dysfunction often causes voiding symptoms. This study found that hesitancy, poor stream, and stop-start voiding significantly predict impaired maximum urine flow rate in women.

Area of Science:

  • Urology
  • Gynecology
  • Pelvic Floor Disorders

Background:

  • Pelvic floor dysfunction (PFD) frequently presents with bothersome voiding symptoms in women.
  • Understanding the relationship between subjective voiding complaints and objective urodynamic measures is crucial for effective management.
  • Uroflowmetry is a key non-invasive test for assessing lower urinary tract symptoms.

Purpose of the Study:

  • To investigate the association between specific voiding symptoms and uroflowmetry parameters in women with PFD.
  • To identify which voiding symptoms are predictive of impaired maximum urine flow rate.

Main Methods:

  • A cross-sectional study involving 414 women with complaints of pelvic floor dysfunction.
  • Free uroflowmetry using a weight transducer flowmeter was performed.

  • Voiding symptoms were assessed via interview and correlated with maximum urine flow rate and its centiles in 356 women with voiding volumes between 50-600 ml.

    • Main Results:

    • 62% of women reported at least one voiding symptom.
    • Hesitancy, poor stream, and stop-start voiding were significantly associated with reduced maximum urine flow rate centiles (p=0.002, p<0.001, p=0.014 respectively).
    • Straining to void and incomplete emptying were not significantly associated with reduced flow rates.

    Conclusions:

    • Hesitancy, poor stream, and stop-start voiding are significant indicators of potential voiding impairment in women with PFD.
    • These specific symptoms are more predictive of objective flow abnormalities than straining or incomplete emptying.
    • Uroflowmetry findings should be interpreted in conjunction with patient-reported voiding symptoms for comprehensive PFD assessment.
