As an update, inspired by this thread I set out to measure my volume per void. I weighed my diaper after a good spontaneous wetting and compared it to the weight of an identical fresh diaper. Assuming that urine has about the same weight as as water, I calculated my voiding volume to be 125 ml.
Here’s where it gets interesting: I read somewhere that most adults will first sense the need to pee around 150 ml. The average post void bladder volume is supposed to be 50 mL or less for someone my age. I don’t have history or symptoms of urinary retention, so let’s say my residual volume is right in the middle: 25mL. That means it’s my functional bladder capacity is right around 150 mL. In other words I spontaneously pee upon my bladder sensing bladder pressure. It’s basically the default micturation reflex at this point. Obviously, I’m making a lot of assumptions here but I will say this is most often what I perceive in my day to day experience…. Reflexive wetting once the pressure hits a certain threshold. Though there are times when my bladder behaves differently.
And, I don’t think it’s a coincidence that this is similar to what others with long term issues such as
@Eclectic and
@cantwait reported well.
Yay science!
