Lancelot:
Unfortunately no.

SPLAT!!!!!

Followed by a rythemic squishing sensation coinsiding with fin kicks. :freak:

Wow...that is quite a disclosure.
 
Hemlon:
Plus, it's some warm fluid in your wetsuit when you're cold!
Actually, the warmth is only superficial. In reality, it makes you colder. That heat in your urine used to be inside your body. Now it's on the outside.
 
Undercurrent had an article recently about a dive op in Hawaii, Scuba Shack, that bans peeing. Here is a reader's response:

Dear Ben: As a physician and diving instructor, I
feel compelled to address some of Mr. Neal’s “aesthetic”
points. Urine is sterile. If it were not, we would all have
urinary, kidney, bladder and prostate infections. Sure,
urine has waste products, especially ammonia, but not
bacteria. While Mr. Neal may not like urine on his skin,
he can be assured that he is not promoting bacterial
proliferation in his wetsuit. The exchange of water in his
wetsuit while diving has a diluting effect on the volume
of urine in his suit. So the idea of dumping urine onto the
carpet and the deck is not going to lead to infections. In
fact, it is theoretically more unhealthy to spit in your mask
and rinse it off in a community rinse bucket, although
this too is unlikely to lead to sickness. The human mouth
harbors more numerous and more toxic bacteria than the
urinary tract. Divers are a “spitting” group -- we spit when
we climb on board, when we have something in our regulators
to clear out, and so on. Perhaps this habit needs to
be banned as well! So I will continue to use hand sanitizers
when appropriate, because shaking hands is far riskier
behavior than peeing in your wetsuit.

Uh, how do you enforce a ban on peeing? How would you know if someone peed their wetsuit?
 
It's a great question--I'd hate to even speculate.
 
A little more insight, again from Undercurrent:

Truth is, peeing in one’s wetsuit is virtually [un?]avoidable
and just fine. Here’s what “Scuba Doc” Ernest
Campbell, M.D., wrote in these pages a few years back:
“Once underwater, the urge to urinate increases.
During a dive, there is about a 60 percent increase in
the work of breathing. Negative pressure breathing
causes divers to lose about 350 cc/hour from their
circulating blood volume. The cardiovascular system
changes. Peripheral blood vessels constrict, driving fluid
back into the core and stimulating urine discharge.
There is no increased central blood volume and output
from the heart increases up to 30 percent. The result?
Urine flow increases four to five times during a dive.
“Holding the urine in could possibly be harmful.
There have been cases of fainting when the stretch
receptors located in the wall of the bladder are stimulated
and a vagal nerve reaction—a decrease in heart
rate, blood pressure and a feeling of light-headedness—
occurs. Fainting underwater is risky to say the least.
“So if you need to, go ahead and pee, even if it is
against your sensibilities.”
