Is it possible to urinate and defecate at the same time

So you can tighten them and hold in your pee or poop, only releasing bodily wastes when and where you choose to. Well, most of the times. The external muscle that we relax when peeing, however, is a lot smaller and easier to isolate than the muscle relaxed when pooping. So when you decide to take a leak, you're able to do so without the general musculature of the pelvic floor relaxing. When pooping, however, apart from allowing solid waste to pass, the relaxation of the considerably stronger anal sphincter also decreases tension in the weaker urinary sphincter, allowing urine to pass simultaneously.

Causing some pretty glorious relief, no doubt. In a nutshell, it's a fight between the shit and piss muscles and shit trumps piss every day of the week, and twice on Sunday. Your child will have an evaluation to best determine the cause of their urological problems.

Many of them are parents and bring a special understanding to what our patients and families experience. Skip to Content. Urgent Care. The muscles are smaller, but the concept is the same. There is both an involuntary internal urethral sphincter and a voluntary external urethral sphincter. The internal urethral sphincter opens when pressures inside the urinary bladder are great enough; we can hold back the urine by tightening our external urethral sphincter, or we can urinate by relaxing this muscle.

So why do we often urinate when we defecate, but not vice versa? The main reason is that the muscles of the pelvic floor play a role in defecation and urination. The pelvic floor muscles relax when we defecate. However, they will not necessarily have to fully relax when we urinate. But when the pelvic floor musculature does relax, in addition to allowing stool to pass, it decreases the tension in our urinary sphincters, allowing urine to flow.
