Each summer, some swimmers and not just kids! That is, what should you do when you need to pee? And if so, is this safe? Urologist Petar Bajic, MD , weighs in on whether you should just go, or find yourself a proper restroom. Learn the scientific pros and cons to consider in favor of holding it — or not. And just how safe is it to swim in public pools if other people have peed in them?
Cleveland Clinic is a non-profit academic medical center. If you have ever wondered why some guys appear to be playing with themselves as they don their drysuits, you now know what they most likely were doing. During the dive, when the need to pee arises the diver opens the pee valve, pees into the water, and closes it again.
I tried this technique when I first started technical diving but there are several problems. Wearing a condom glued to your penis for several hours is not particularly comfortable. If the catheter slips off the pee valve you will pee into your drysuit not uncommon.
If the pee valve leaks you also get wet. Finally, condom catheters are use-and-throwaway and the cost does add up. Female tech divers have similar options. They can use diapers. They can use the female equivalent of a condom catheter and pee valve see www.
This silicone device glues to the skin and has a tube that attaches to a pee valve. I do not know any female divers who have tried this device but it likely has shortcomings similar to the condom catheter. Both sexes could catheterize themselves and wear a bag under the drysuit or connect the tube to a pee valve. This is a better option for females since the urethra tube from the outside to the bladder is very short and catheterization is normally a simple procedure. In my opinion there is a better solution for both sexes.
The body signals the kidneys to produce more or less urine via the antidiuretic hormone ADH ; natriuretic peptides and the renin-angiotensin-aldosterone system primarily control electrolyte excretion. As the level of ADH decreases the kidneys produce more urine. In a tech diving friend mentioned that some racecar drivers took a chemical to avoid having to pee when racing and he wondered if this would be safe to use while diving.
I investigated and found that they were taking desmopressin acetate. This chemical is readily available because it is commonly used to treat bed-wetting in kids. Taken before bed it helps youngsters reduce urine production so nighttime peeing is unnecessary. In fact, desmopressin acetate is a synthetic structural analogue of ADH. This struck me as a perfect solution.
Not only would it eliminate the problem of having to pee during a dive, it should counteract the production of urine due to immersion and cold, and it should reduce the risk of DCS. DDAVP comes in several forms nasal spray, sublingual tablet and tablets you swallow. I swallow a 0. Urine production is reduced but not eliminated. After six or seven hours in a drysuit I can go for a pee at my leisure and then do another six to seven hours in the drysuit without difficulty.
Children over age five can take up to. At this dose there is virtually no downside. At higher doses, if the person also consumes large quantities of water they can upset the electrolyte balance in the body. Also at higher doses, when the drug wears off a significant quantity of urine can be produced to restore fluid balance. I have been using DDAVP before long dives for 12 years now and still believe it to be the best option.
