What characterizes reflex incontinence?

Reflex incontinence is characterized by involuntary urination that occurs at predictable intervals related to the volume of the bladder. This type of incontinence typically arises from a disruption in normal bladder control mechanisms, often due to neurological conditions. In individuals with reflex incontinence, as the bladder fills to a certain volume, it triggers a reflex that leads to the release of urine without the person being aware of the urge or having control over the timing.

This distinct pattern differentiates reflex incontinence from other forms. For instance, incontinence due to sudden urgency involves an immediate and strong urge to urinate, often leading to leakage before one can reach a bathroom. Lost urine at unpredictable times suggests a lack of control over the urge and release, but without the regularity found in reflex incontinence. Incontinence during physical activities, such as sneezing or exercising, typically relates to stress incontinence, which is not centered around the bladder's volume but on increased abdominal pressure. In contrast, reflex incontinence’s regularity linked to bladder fullness is what makes it unique.
