There were different sensation-related voiding patterns on the 3-day SR-BD from incontinent women and healthy volunteers. All incontinence groups had increased bladder sensation compared to healthy volunteers. The most severe increase of bladder sensation was observed in the patients with urgency incontinence.

Increased bladder sensation is the most troublesome symptom of overactive bladder. In clinical practice, reliable noninvasive evaluation of bladder sensation is needed. This study was designed to determine the reliability of a 24-h sensation-related bladder diary (SR-BD) in women with urinary incontinence including clinically relevant information regarding the bladder sensation. A total of 246 women with urinary incontinence filled out a SR-BD for 3 days. They graded the perception of bladder sensation at each micturition and measured the volume voided. The reliability of the 24-h SR-BD method is preserved, when taking into account the grade of bladder sensation. The 24-h SR-BD, which incorporates bladder sensation at each micturition, not only gives information on sensation-related micturition behavior but also shows good reliability. Grading of bladder sensation does not jeopardize this methodology but on the contrary provides added value, which is clinically relevant.

During conventional cystometry the patients with different types of incontinence experience the degrees of desire to void at larger volumes than in daily life. Sensation related symptoms will thus be more accurately studied with the SR-BD than with cystometry.

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.
