Detrusor-Overactivity-Related Voiding in Women Mimics Bladder Outflow Obstruction and Conceals Underactivity.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveUrodynamics of the storage phase showing detrusor overactivity is com- mon in neurogenic bladder patients. Terminal detrusor overactivity, which is defined by involuntary detrusor contraction that cannot be inhibited, causes urinary incon- tinence. Such incontinence causes a unique voiding in neurogenic bladder patients. During the voiding phase, the detrusor pressure at Qmax (Pdet.Qmax)/maximum flow rate (Qmax) (P/Q) is the gold standard for differentiating between detrusor underactiv- ity and bladder outflow obstruction. We investigated whether a valid identification of lower urinary tract dysfunction could be established from P/Q assessment of detrusor overactivity-related voiding patients.
methodsThis study evaluated 2 types of voiding. Detrusor overactivity-related void- ing is involuntary detrusor contraction that results in micturition or voiding after per- mission to void when detrusor overactivity has occurred, while voluntary voiding is voiding voluntarily after permission to void and without terminal detrusor overactivity. We evaluated female patients with neurogenic bladder who could undergo micturition without catheterization. A pressure flow study compared the 2 groups.
resultsComparison of the detrusor overactivity-related voiding group (n=20) and the voluntary voiding group (n=12) found statistically significant differences with a lower Qmax and higher Pdet.Qmax (P=.01) in the detrusor overactivity-related void- ing group. The linear regression analysis P/Q plot showed the positivity and negativity value of the slope that was reversed in the 2 groups (-0.089 vs. 0.198).
conclusionCurrent results showed different P/Q plot patterns between 2 types of voiding in patients with neurogenic bladder. These findings suggest there is increased detrusor pressure observed in detrusor overactivity-related voiding that mimics out- flow obstruction.
