Certain medications and supplements, such as B vitamins, might also cause an usual urine odor. Fresh urine has little to no odor. But if urine sits for a time — as can happen when a person is wearing protective underwear or an incontinence pad — the urine will begin to smell like ammonia. The smell is caused by bacteria that break down urea, a substance that is excreted in urine. Changing the disposable undergarment or absorbent pad and washing the area with soap and water will remove the odor. If your urine is dark and strong smelling, you may be not be drinking enough fluids.
This is known as hypohydration. On average, men need approximately 4 quarts of total fluid daily and women need roughly 3 quarts, according to the Institute of Medicine. Taking in less fluid than your body needs or losing too much fluid through sweating, vomiting or diarrhea can result in hypohydration, or even dehydration. In otherwise healthy adults, simply increasing your intake of water can return your urine to its normal color and odor. A very strong ammonia smell may indicate a severe infection, although some people with a UTI do not notice a change in urine odor. Other symptoms of a UTI include burning pain with urination and the need to urinate frequently but passing little urine.
Fever and back pain might also occur. Contact your healthcare provider if you suspect you might have a UTI. A sweet or fruity urine odor is typically caused by chemicals called ketones, byproducts of fat breakdown. Ketones in the urine can be a sign of undiagnosed or poorly controlled diabetes. You can also have high concentrations of ketones if you’re not eating much due to dieting or the stomach flu. If you’re not dieting and notice a fruity odor to your urine, contact your doctor right away — especially if you have diabetes. An abnormal connection between organs, called a fistula, can occur between the vagina or bowel and the urinary tract.
Because the urine is not draining properly, it typically takes on a strong, unpleasant odor. A fistula between the urinary tract and bowel can also cause passage of gas and stool-like material in the urine. Contact your doctor immediately if you have symptoms that might indicate a fistula.

The person is sexually aroused by wetting one’s clothing or observing another person doing so. The warm sensation felt when urine trickles on the body seems to give very relaxing and pleasurable feelings to the person. In many cases, that person is also aroused by smelling body parts that have a urine scent. Others get aroused by telling some people about when they lost control and wet themselves.
Some prefer a particular type of clothing to urinate. Becoming noticeably desperate or wetting oneself with the express purpose of being seen by strangers. Practitioners have described going to public places such as a mall or a park. Some intend to create situations where others can see their wet clothing. The act of holding one’s own urine until the need to urinate is urgent, making another hold in their urine, or watching another person with an urgent need to urinate. This fetish sometimes originates from childhood memories of needing, or of seeing another needing, to urinate. Arousal may be triggered by seeing the body movements or facial expressions of that person. It can also be heightened by the person saying that they have to urinate. The arousal from being desperate comes from the sensation of having a full bladder. The strategies and tactics that are used to smuggle one of the couple into and out of the toilet undetected are as important or almost as important as the urination. The activity is done by itself or as a part of or prelude to other activities which many times involve sex. Seeing another urinate without the person’s knowledge either through video taping by a hidden camera, or by lurking in locations where people are urinating or are likely to have an urge to urinate.
