Increased Bladder Sensation is the Most Troublesome Symptom of OAB/Overactive Bladder

Newswise — Our group evaluated a 3-day Sensation Related Bladder Diary (SR-BD) from 246 incontinent women. The analyzed group consisted of 102 women with SUI, median age 54, range (23"86); 80 women with UUI, median age 59, (15"85); 64 women with MUI, median age 57 (15"77).

The patients graded the perception of bladder sensation at each micturition and measured the volume voided. A 24-h period was defined as the period between the first void when waking up to the first void the next morning when waking up again. The participants were asked to fill out time and volume of fluid intake, time of micturition, and voided volume with grading of bladder sensation at each micturition. Bladder sensation was graded according to the following definitions: grade 1—no desire to void; grade 2—desire to void but voiding can be delayed for at least 30 min; grade 3—desire to void and voiding cannot be delayed for more than 15 min; grade 4—desire to void and voiding cannot be delayed for more than 5 min. Reliability was tested by means of the intraclass correlation coefficients of the SR-BD parameters between the first, second, and third 24-h period. We were able to show in this study that the 24-h fluid intake, the 24-h voiding frequency, the 24-h total voided, the mean voided volume, and the distribution of voids according to the different grades of bladder sensation were not significantly different over the three 24-h SR-BDs. The ICC values for voids made with desire to void (grade 2, 3, and 4) were in the range of moderate to good reliability.

The SR-BD, which incorporates bladder sensation at each micturition, not only gives information on sensation-related micturition behaviour 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.
