My bladder defies the laws of physics: 8oz of fluid goes in, 16oz comes out! It’s truly amazing! I swear, sometimes I feel like a walking pee factory! FU old age! :mad: 🙂 ---

About 60% of your body is water so it’s like saying you were able to pour a liter of water into a lake and then draw 2 liters out. That’s worth a sarcastic golf clap at best. 😉 ---

> [@Grrr](#): > > My bladder defies the laws of physics: 8oz of fluid goes in, 16oz comes out! That’s hardly surprising. Infuse 8 oz of fluids into your bladder via a catheter tube up your urethra, and even as you do that, two ureters are filling it up also, from your kidneys. So of course more will come out than you put in to it! My question is why you’re putting fluids into your bladder that way? What fluids? To what end? Chemo for certain cancers or interstitial cystitis treatment? Internal prostate massage? Endorphin induction? For the halibut? 😕 [sub]at least you can still get a catheter up there. wait until your prostate is huuuge, and then try it. ugh[/sub] ---

**Grrr!** , does your bladder also follow you around like in the drug ads? I have no idea why those patients don’t carry a gun and blow the persnickety little pain in the ass away. :mad: My sympathies to all who are bladder-afflicted. ---

In less than three weeks, I expect to be spending anywhere from 2 to 5 hours [in a place](https://i.ytimg.com/vi/IhBx9bhFIGs/hqdefault.jpg) where there simply won’t be a opportunity to pull over to the side of the road to take a leak. (Yes, that’s me in the floppy hat in that picture.) For us older male farts with older male problems, that can get, um, uncomfortable. I test-drove a set of Depends and didn’t find it quite adequate to the task. Now I’m wondering if should be looking into a condom-style catheter with a pee bag. ---

> [@Weisshund](#): > > I vote for a short rubber tube poking out the floor of the plane. > The prop wash should hide all the evidence? This IS commonly done, in fact. Ix-nay on the prop wash though: Pee all over the prop would _not_ leave it very clean. Besides, there’s no prop. It’s a glider. A lot of gliders have a plastic tube of some sort leading to a hole in the floor, and the condom catheter tube can be stuck into that. (Sorry, the glider I’ll be flying does not.) [XCPee Base Kit](https://www.xcshop.com/shop/product.php/511/xcpee-base-kit) (XC refers to cross-country flights in which this could be useful.) [Glider Pee Tubes](https://darrylramm.wordpress.com/glider-pee-tubes/) Instructions for DIY pee tube. Now, lest this sub-topic be considered a hijack, one may consider: Is this something that could be useful to OP and all others similarly situated? Cross country glider soaring is largely done over rural areas. The area where I expect to be (I posted some pics in another nearby thread) is mountainous, but a popular mountain biker territory. Those bikers better wear their rain hats! ---

Infuse 8 oz of fluids into your bladder via a catheter tube up your urethra, and even as you do that, two ureters are filling it up also, from your kidneys. So of course more will come out than you put in to it! I’d didn’t read the OP as meaning exactly that. I assumed he meant infusing 8 oz fluids per os, excrete 16oz per dick. Anyway, it’s really unpredictable. Me, some days I can go all day (or all night) without having to pee, other days I’m taking a little leak every 30 minutes or more, sometimes by day, sometimes by night. I’ve haven’t been able to spot a clear correlation between that and how much I’ve been infusing (per os that is). I assume **JackieLikesVariety** is asking the OP, not me, if a diuretic is in use. I’ve done some occasional lengthy flights in airplanes recently too. The pilot-in-command (not me), it turns out, is a caffeine addict, and has to pee even more often that I do, despite being only 22 years old. That’s feasible in a little airplane, because we can land at any nearby airport, deal with it, and take off again. In fact, I’m going to e-mail him Real Soon Now and ask how he deals with his XC glider flights. Whatever the solution here, it sounds useful also for those hundreds of people who get stuck, all at once, on a commercial airplane at the airport who aren’t allowed to get off the plane for hours on end. If it were me, I think I’d pee and shit right there at my seat, and urge all other passengers to do the same. The airline can think about that when they replace all the upholstery and carpets. ---
