Blowing air through your urethra

What would happen to me if I inserted the red straw from a "compressed gas" duster into my urethra and pressed the trigger, say, for about 5 seconds or so?


I imagine it would be terribly painful, but would I suffer long term consequences from this stunt?

It would certainly damage you internally.

Don't forget that those "canned air" units (if used incautiously) can directly expel hydrocarbon fluid that evaporates causing extreme cooling - and the expelled air is a fluorocarbon anyhow. I would not want that in my bladder.

Quote:
If the can is held upside down, then its contents are expelled as a liquid. This liquid evaporates very quickly at standard temperature and pressure, chilling anything in contact with it. This process can produce very cold temperatures, easily sufficient to cause frostbite. Similar cans with dip tubes are marketed as "freeze spray," and will expel liquid when held right side up.
Not a good idea at all.

I have to think you could search Youtube and find someone doing it. This is the internet, after all.

The real trick would be to find someone doing it twice.

The air embolism is a very real possibility. Surviving that, the necrosis from frostbite after freezing the very delicate tissue inside the urethra would ruin your day.

People seriously underestimate the power of air pressure. Even if we're talking just 1 psi of overpressure, the pressure inside your bladder would be a few pounds to start with. That would be enough to expand the bladder, which would increase the total pressure even further. It's like a chain reaction until something ruptures. And you'd better hope the thing that ruptures is just the bladder so that the pressure doesn't move up the ureters to the kidneys.

PS: If you could insert that little red straw at all, I'd be amazed. That would have to hurt like I can't imagine.

This would be an awful thing to do. And yet a part of me want you to try it and get back to us on the result.

That little red straw is pretty sharp, and would definitely damage the urethra. You'd have a lot of bleeding from a tear, long before it got to the bladder . . . which would never happen anyway, since the straw's too short. So what would happen is that you'd poke a hole in the side of your urethra, then blow air into the "meat" of your penis, causing serious injury.

Once I had my bladder scoped and you would not believe the size of the MF that they threaded up mine. That little red straw is nothing, in terms of diameter. (Notwithstanding, it would be a very bad idea to blow air up there.)

I am curious as to why people think it's likely to get an air embolism and die from this?

An air embolism is when an air bubble forms in the VASCULAR system, forming a potential clot and such. But your urethra is not part of your vascular system. It's part of the renal system and leads up to the bladder. You would basically be blowing air up and either into your bladder (or way less likely) into your spermatic ducts and tubes and such things. I suppose if you followed the ureters then up the bladder, you'd get to the kidney, and THAT's where the first hints of a vascular system occur, but the idea of air being able to go up the urethra, into the bladder, thru the ureters and then into the kidneys to form an embolism is HIGHLY dubious. More likely is that the bladder would inflate with a possible rupturing inside, causing a possible peritoneal infection.

So where's the Air Emboli logic coming from? Unless you're saying that instead of sticking it up your urethra, you're trying to stick the tube into a vein or an artery the chances of the air embolism forming are slim to none, right?
I think my interpretation is right, but I'm willing to hear the other side.

I don't know about anyone else, but I have a vascular system right there in my penis.

Sure, my vascular system is not directly plumbed to my urethra, but that's under the specific, normal circumstances of not having a sharp plastic object jammed in there, venting gases.

No one said it's likely.
However, there have been cases of fatal air emboli after sexual intercourse - I would think that injecting high-pressure gas internally runs at least as great a risk.

Well dont WE have a schmancy fancy penis....

We havent even considered the shrinkage factor yet....the life and death stuff is taking precedent for some strange reason.

Well, the bladder itself is relatively impermeable. And I've been in many procedures where some type of contrast material (an iodine-based fluid) is injected retrograde into the ureters in order to visualize them as well as the kidneys, but from the patients' reactions (those not under anesthesia), it certainly doesn't look to be much fun.

I'm sure an M.D. or two will be along shortly, but it's my layman's guess that an embolism wouldn't be the first concern. I'd tend to lean toward worrying about a rupture and subsequent infection.

Well that's why I'm making the difference there, if you're willingly doing this to yourself, I'm assuming you've taken the time to insert the tube in properly- ie: you've not jammed it into the vasculature. That's why I'm curious as to the emboli issue, I believe it's a non-issue if the tube is still in the (relatively intact, maybe slightly inflamed) urethra. The actually high powered air/freezing issue itself is the more the damning issue than a risk of embolism.

Yes, indeed. It's called 'sounding', but it generally involved using solid objects (dulled knitting needle, carriage bolt, etc.) rather than air. May sometimes be done with liquids, I think.

These cans are high pressure air. Something will rupture and you'll bleed out. The embolism or frozen necrotic wanker won't even matter.

Or peritonitis? IANAMD, but I think an intermediate possibility might be blowing out your bladder and causing peritonitis from the torn open bladder.

What say the MDs in the audience?

That's what my thought was earlier, especially if you got the tube far enough in. It'd be easier in a woman though to get to that bladder, though there's def. a greater chance of tissue damage and all though, if you held it down and kept going, I'd say you blow out the bladder and bam! Peritonitis.

Not a doctor yet though so I'll easily defer to any Doc that wants to take this one on.

Since the bladder is kinda stretchy, do you think the ureters or part of the renal pelvis might blow before the bladder?

Hm.

I'll run this past one of the urologists the next time I see 'em. They can't think I'm any weirder than they already do.

I own a set of sounds, and believe me, the ends are very rounded and smooth. And even then you have to insert them very carefully, with sufficient lubrication, into a totally flaccid penis. And they need to be properly disinfected.

Sounds also have a bend or knob on the non-inserting end, to prevent the whole thing from getting accidentally inserted. (Imagine what the ER will have to do, to fish that sucker out.)

Do not insert anything sharp into your penis, with or without a burst of air.

By the way, the reason some guys do this is, if the sound is long enough and the penis is short enough, you can stimulate the prostate. There's no reason to go all the way to the bladder, unless you're a medical professional clearing an obstruction.

On further consideration, we need to take male/female into account. And, are we just considering where the first blowout will occur?

If male, would the first blowout occur in the vas deferens?

I love this forum. I was using a can of "dust destroyer" this morning and the thought came to my head: "hey, what would happen if I stick this in my peenor? I think I'll just post it at Straight Dope!".


I was also going to make a quip about how crappy a "blow job" this would be but I thought against it.

Assuming Livardo is male, the straw on the can probably wouldn't reach the bladder. When inserting a catheter into the bladder, on a male the urethra is 17-23cm long (6.7-9"). It would be easier in a female, since their urethra is only about 4-4.5cm long (1.6-1.8").

So just my WAG, most of the damage in a male would be to the urethra and the bladder - I have no idea how far up the system the gas would travel. Urine travels from the kidneys to the bladder via the ureters; where the ureters join the bladder there are one-way valves to prevent backflow of urine into the kidneys (ureterovesical valves). Presumably these valves would fail when under pressure, but googling quickly I couldn't get any information on how much pressure it would take.

You bet it can happen. Fatal air embolism from trauma to that area is well reported.

Here's a brief case just to illustrate that a rather small cut of the urethra (peeing tube) can lead to fatal air embolism. And that's not even with the air being put in under pressure. Just cutting the urethra at the same time as the bladder neck (bottom part of bladder through which urethra passes) can cause it.

Here's a similar case which also happened during prostate surgery.

In fact, there a good number of published cases of fatal air embolism in both human and animals (but not linked to - at least not readily).

I think what may be causing some SDMB'ers doubts about the possibilty of this happening is that people may generally be unaware that much prostate and urethral and bladder surgery allows air to enter (and stay in) the bladder (as a result of having that great tube inserted into the urethra.

This discussion inspires a catch phrase that is way better than that oldy but goody "quit trying to blow smoke up my ass".

The details and actual construction of the 21st century version are left as an exercise for the reader.

Oh, I don't have any doubt that an embolism could occur, I'm just wondering what would happen first--supposing that there wasn't any type of incision/accidental puncture, and that air pressure alone was the determining factor.

Where's the weakest point at which a 'blowout' would take place?

This.

Stick the air nozzle halfway into the end of a hot dog and press the plunger for a couple seconds. Really, give it a try. You'll get a very good idea of what you'll be dealing with.

Sounds like a can of compressed air is NOT recommended for generating on-demand dickfarts/manqueefs/woodwinds.

FIVE WHOLE SECONDS ????????????????

My WAG is that you'd pass out from the pain before the second second. Or at the very least, you'd let go of the can from sheer surprise.

Here's a somewhat safer experiment you can try, sort of as "practice" or a "warmup" to the above: Put a couple of fingers around that tube. Then try and hold those fingers real tight, perhaps in a fist, to approximate how there's no escape route from the penis for all that compressed gas. Then be amazed at how impossible it is to hold that gas in.

Heh.. I was going to say 30 seconds but that seemed a little excessive.

Thanks for this. In the years since I first heard of sounding, I'd never been able to figure out why anyone would do it. Still leaves me curious how it was first discovered to be pleasurable, though.

I'd speculate that that's the minority, there's much simpler ways to stimulate the prostate after all. The majority probably do it for less mechanical reasons, such as the thrill of the forbidden, unusual or unique and the masochistic thrill of body modification and pain. They sell graduated sizes for a reason afterall, you can't discount the presumed wow-factor in fetishes.
