Do sensation-related bladder diaries differ between patients with urodynamically confirmed and non-objectivised urinary incontinence?

The aim of the study is to investigate whether sensation-related bladder diary (SR-BD) differs between women with symptoms of urinary incontinence (UI) in whom incontinence is not demonstrated during investigation and women with demonstrated UI. Two hundred and six patients with stress UI, urge UI and mixed UI filled out a SR-BD for 3days. They graded the perception of bladder sensation at each micturition and measured the voided volume. Incontinence episodes and the severity of leakage were recorded. All had cystometrogram. The patients were divided in urodynamically confirmed and non-objectivised UI within each type. More disturbed bladder sensation was present in urodynamically confirmed urge UI and to a lesser extent in mixed UI than in the respective non-confirmed groups. No such difference could be seen in stress UI. Close interpretation of the SR-BD may indicate to a certain extent the presence of detrusor overactivity in urge UI and to a lesser degree in mixed UI.
