Summary

Urinary symptoms in Parkinson's disease patients often indicate bladder dysfunction. Patient-reported symptom scores can accurately predict the type and severity of these urodynamic abnormalities.

Area of Science:

  • Urology
  • Neurology

Background:

  • Parkinson's disease (PD) frequently causes bladder dysfunction.
  • Urinary symptoms are common in PD patients, impacting quality of life.

Purpose of the Study:

  • To evaluate bladder dysfunction in Parkinson's disease patients.
  • To determine the correlation between disease severity and urodynamic abnormalities.
  • To assess if subjective urinary symptoms predict urodynamic findings.

Main Methods:

  • Seventy Parkinson's disease patients with urinary symptoms were assessed.
  • International Prostate Symptom Score (IPSS) and urodynamic tests were utilized.

Main Results:

  • Urodynamic abnormalities were prevalent, with detrusor hyperreflexia in 67% of patients.

  • Abnormalities increased with PD severity, though only post-void residual urine volume correlated significantly.
  • Symptom scores correlated with urodynamic parameters, predicting over/underactivity during storage and voiding phases.

    • Conclusions:

    • Bladder dysfunction in Parkinson's disease may worsen with disease progression.
    • Subjective symptom scores are reliable predictors of urodynamic abnormalities.
    • Quantifying urinary symptoms aids in assessing the severity and type of bladder dysfunction in PD.
