Summary
Frequency of urination is the key symptom linked to overactive bladder (OAB) and objective measures. Reporting urinary frequency is essential for diagnosing OAB.
Area of Science:
- Urology
- Gynecology
- Urogynecology
Background:
- Overactive bladder (OAB) syndrome is characterized by urgency, frequency, nocturia, and urge incontinence.
- The relationship between subjective OAB symptoms and objective urodynamic findings requires further clarification.
Purpose of the Study:
- To investigate the association between overactive bladder symptoms and objective parameters from bladder diaries and filling cystometry.
- To determine which subjective symptom best correlates with objective urodynamic findings.
Main Methods:
- Retrospective review of 95 women undergoing urodynamic investigation.
- Assessment of urogenital symptoms and quality of life using the Urogenital Distress Inventory (UDI) and Incontinence Impact Questionnaire (IIQ).
- Analysis of 48-hour bladder diary data and filling cystometry parameters.
Main Results:
- Urinary frequency and urge incontinence symptoms significantly correlate with detrusor overactivity.
- Frequency and urgency symptoms are associated with lower micturition and bladder sensation volumes.
- Multivariate analysis shows frequency is linked to higher 24-hour voiding frequency, lower maximum voided volume, and reduced sensation volumes during cystometry.
Conclusions:
- Urinary frequency is the strongest predictor of objective urodynamic findings and detrusor overactivity among OAB symptoms.
- Subjective reporting of urinary frequency is crucial for diagnosing overactive bladder syndrome.
- This study highlights the importance of bladder diaries and cystometry in evaluating OAB.
