Bladder diary patterns in detrusor overactivity and urodynamic stress incontinence.
Journal Article (Journal Article)
AIMS: Our aims were: (1) to describe and compare frequency-volume and incontinence episode patterns in patients with urodynamic stress incontinence (USI) and detrusor overactivity (DO) as measured by a hand-written and computer-analyzed bladder diary and (2) to compare degree of separation between these clinical groups produced by raw diary measurements and after age- and total-volume-adjustment against a reference population. MATERIALS AND METHODS: We studied 58 patients with USI, 29 with DO, and 22 with both USI and DO. From 3-day hand-written and computer-analyzed bladder diaries, we calculated average and maximum volume voided (Vol/Void), voiding frequency and volume voided over 24 hr, and number, size and type (whether accompanied by activity or urge) of incontinence episodes. RESULTS: Compared to the USI patients, the DO patients tended to have (1) higher voiding frequency, (2) lower Vol/Void, (3) more urge-related, than activity-related leaks, (4) smaller volume, and equally frequent leaks and (5) more severe incontinence symptoms. The age- and volume-adjusted percentiles better separated the USI and DO groups' frequency and volume measurements than did the raw measurements. Unexpectedly high percentages of our USI patients had low Vol/Void measurements, high voiding frequency, and predominantly urge-related leaks. A subgroup of 29 USI patients with "low" (average volume <30th reference population percentile) Vol/Void measurements had high incidences of urgency and urge-related leaks. CONCLUSIONS: Reference population percentiles better separate the frequency/volume patterns of USI and DO than do the raw measurements. We found a subgroup of USI patients that had an OAB-like clinical picture.
