Medical Forum / Diseases and Disorders / Prostate Cancer / July 2005Sphincter Muscle ?
Someone mentioned to me that women have only one sphincter muscle to control the flow of urine. Is this true?? TIA, Sandy K. Yes, from all that I've read. B.A. > Yes, from all that I've read. > B.A. So, if women only have one sphincter muscle to control the flow of urine, I wonder why we men have such difficultly with incontinence if one of our two sphincter muscles is removed from RP surgery?? Sandy K. I have no clue. But after a few babies - well, never get in the way of a woman, on her way to the bathroom, who has sneezed or coughed! I think the problem is larger than it may seem but it is not discussed.

First of all, we men have 2 sphincters. The so-called third is the prostrate itself due to its restriction to flow. From this perspective, 2 of our three are removed. And the remaining sphincter is often damaged during surgery. Also, at least a few of the nerves that control that last sphincter in men are in those precious nerve bundles docs try to preserve during the surgery. So, not only is the muscle itself often damaged, some of its nerves are too. In addition, the muscle is being asked post-op to do more than it ever had to do before and with the normal atrophy from aging, the drips-in-the-pants syndrome is rather common. Dave Perry Part of the problem is that men have nmore muscular bladders to force the urine out past two sphincters and the prostate (which is itself muscular and capable of some contraction). The other part of the problem is that the final sphincter is not called upon to do much work most of our lives (pre RP). So post RP we end up with a weak sphincter trying to restrain a powerful bladder.  SignaturePeter Headland I think perhaps there is some confusion here between sphincter and Kegel. I suggest that you check out www.Answers.com for sphincter (there are four) and the following site for more info about the Kegel: http://www.answers.com/main/ntquery;jsessionid=cmoi249fg9h7g?tname=urinary-incon tinence-1&curtab=2222_1&hl=kegel&sbid=lc03a Ken Bland > Someone mentioned to me that women have only one sphincter muscle to control > the flow of urine.

If I do remember well, the 'other' sphincter with women is part of the uterus. Douwe > Someone mentioned to me that women have only one sphincter muscle to control > the flow of urine.
