Cyclingboy: Sorry, it is more like two sphincters are removed. The one at the neck as indicated and the less formal one that the prostate gland provided. So you are left with the pelvic floor muscle to do the job. Urination is actually a very complex voluntary and involuntary act. It is hard to find a good lay person text that explains it well. Both the brain and muscles work in concert to
open passages and trigger muscles to empty your bladder.
I get the same feeling in this recovery period. Will I have to always think about and hold back my pelvic floor muscle so I don't void when I don't want to? My understanding and please guys correct me if I am wrong, is that once proper healing takes place the pelvic floor muscle is toned to the point where it keeps the sphincter closed. Further the sphincter is healed to the point where it wants to positively hold back urine.
I think the fight for continence boils down to this: The pelvic floor muscle is still in training or perhaps very strong but the sphincter has not healed yet and still leaks so that despite a great conditioned pelvic floor muscle, the sphincter does not seal properly yet because it has not healed enough to form a strong seal.
Otherwise, all it would take for everyone is a few weeks of conditioning the pelvic floor muscle and ta-da, we would all stop leaking very shortly. Despite the exercises, the unknown variable is how long it takes for the body to heal the sphincter.
Please don't anguish over this so soon after your surgery. Most folks are barely back to feeling like going to work at 20 days after surgery if they are leaking and still have some pain/discomfort issues. Even when you get to the point where standing still does not inspire leaking, when you walk for a time before proper healing takes place, you will leak some. So your 20 ml per hour will start to fall to smaller and smaller amounts.
Patience, patience, patience.
