How we (men) control our flow ...

Hi all,

Still trying to understand the reason why we often end up leaking (especially given how much a pain it is to many) after prostate work and this is my interpretation so far.

From Wiki (and other places etc), there are basically two sphincters that do this, one involuntary (It happens on it's own, by default, we don't have to think about it), one voluntary (that we actually have to make happen ... like for the few seconds when doing PF exercises)?

The involuntary one (internal urethral sphincter) is in the base of the bladder and is the primary one, typically staying closed unless we intentionally decide to let it go.

The voluntary one (external urethral sphincter) is secondary, below the prostate and supported by the pelvic floor muscles and so only activates (closes) when we ask it to, like if we are busting to go to the loo but can't for some reason (or typically women after childbirth when they cough or sneeze).

So, what is it that happens during prostate work that negatively impacts the primary sphincter in the bladder??

eg, If say surgery interferes with the secondary sphincter / valve, the only one that interacts with the PF muscles, how does that explain us leaking when it's never the one that normally (subconsciously / involuntarily) holds any flow?

I can see how doing pelvic floor exercises would help prevent surges (like when we are 'busting' or sneeze etc) but not the everyday 'just going for a walk and don't need the loo' type?

Personally, I think it may have more to do with having a catheter stuck though the primary sphincter for a couple of weeks and not allowing it to close properly (muscle wastage, 10%/week or distortion) may be more to do with it but I'm hoping someone with the right medical qualifications could give me the right / medically provable answer please?

If it is the primary sphincter that becomes 'effected' because of the catheter, what if an alternate solution could be found, especially considering how negatively impacting on everyday life it seems to be in some cases? Like, what if the urethra could be joined internally and externally where the internal joint protects the join from infection and allowing it to heal and then dissolves away, once the external one has also healed to return full flow?

Interested / engineering / practical minds etc.

  • Hi Able

    I don't think you are going to find the answers to your questions here.

    The Community is aimed at people/relatives with cancer to be able to share their PERSONAL journey through cancer. The Community guidelines ask medically qualified people to stay away.

    If we have any Community members with the personal knowledge to respond to your post, you may well receive a reply. Your question would be best directed to your Urology Specialist - i am sure they may well be interested in sharing their knowledge.

    Best wishes - Brian.

    Ah, sorry and thanks for that heads-up mate.

    Do we know why such guidelines are in place though as wouldn't we appreciate answers from the horses mouth so to speak?

    And surely, whilst I understand this is urology question, it has only come up as a result of prostate cancer and IS clearly something that many prostate cancer and family here suffer with / from?

    Again I would appreciate the 'why'. ;-)

    (Off to look for a urology forum ...)

  • People who have "been there done that" can freely share their knowledge and experiences with others on a cancer journey. The Community is a "safe space" for inclusive supportive discussions.

    Medical staff are required to stick to giving documented advice and treatments in their place of work where they are fully insured against medical negligence.

    I think that's the "why" you 're after.

    Best wishes - Brian.

    It is indeed, thanks Brian.

  • Think you'd make a great urinary specialist able, keep going Sweat smile wot u are saying makes sense as well.

  • Hehe, thanks Steve. ;-)

    Actually, I've thought a bit more about the mechanics of it. Because the two valves on our urethra are a small distance apart, you can see how we could get a bit of leakage, if we do  something that means the 'main' valve leaks but we hold onto it for a short time with the second. That fluid is then trapped till we let go (as the second is a voluntary one) and then that short length of pipe empties (and why ladies will often wear 'accident' pads in case they sneeze etc) etc?

    It's like you turn off the outlet tap on the water tank in the loft then turn on the downstairs tap till it runs dry. If you leave that tap open and the tank tap leaks, then you will just see that leakage at the downstairs tap. But if you put your thumb over the downstairs tap, all is fine as long as you hold it there but as soon as you let go, you will get all that has built up in the pipe in the meantime (and like with the boy with his finger in the dam, can't hold it forever).

    So the solution is to fix the leaky tap ... and I don't believe that's done by exercising the pelvic floor muscles alone? <shrug>

  • Let's call a plumber for advice Grin

  • Joking aside, I fully plumbed this house when I bought it 40+ years ago so I've been there done that. ;-)

    I visited my plumber mate and he was just finishing off bleeding his own radiators. He said he was struggling with one small radiator in the hall that was only getting warm at the bottom. It was obvious that he had tried to bleed it as he had the bleed screw in his hand. I asked if he had some fuse wire and he found some, I 'pricked' the bleed hole to then hear the sound of escaping air and was just able to get the bleed screw back in before we lost too much fluid! ;-)

    He said 'I'll probably never live this down' and I've tried to make it so. ;-)

  • See, it's not just yer own plumbing u can sort out . ThumbsupGrin

  • Quite Steve and whilst I don't think for one second I'll be able to come up with some new idea about how to fix this obviously troublesome issue for many, you never know?

    It seems to add a bit more information re how it all works here:

    "The pelvic floor muscles are the layer of muscles that support the pelvic organs and span the bottom of the pelvis, forming a muscular support across its base. In men, the pelvic floor muscles support the bladder and bowel. Sphincters at the base of the bladder and underneath the prostate gland help to prevent urine leakage. Portions of the pelvic floor muscles wrap around these valves to assist them in staying closed."

    Whilst it says "Portions of the pelvic floor muscles wrap around these valves to assist them in staying closed" (it says valveS), I don't know if they really do support the upper / internal valve?

    And if it doesn't, what causes the upper one to leak after PC surgery (Other than having a catheter poked though it for 2+ weeks)?
