A friend of mine said they were getting their bladder imaged once and noticed that when they coughed, they could see some urine entering.

My understanding is that the kidneys constantly process urine, and some can kind of be squeezed out of them if you add pressure. So when you ‘push’, you’re probably pressing some extra urine through your kidneys’ filters and into your bladder.
