Each person is different depending on age, health, hydration level etc... Most people can hold their bladder from 4-6 hours but this can vary greatly depending on the above factors.
Around 3 and a half hours for children, adults longer.

you are unable to empty your bladder full of urine
Increasing urine pressure due to contraction of the full bladder
They are stretch receptors. As your bladder fills, these receptors are gradually stretched until they reach a stretch level high enough to enter your consciousness as a need to urinate.

Why does a full bladder cause headaches
It should be easier to pee when your bladder is full because there is more pressure on your bladder. If you are having trouble peeing, see a doctor.
The need for a full bladder for an ultra scan is that the urine creates a window for the beams to pass though. It also helps any technicians know where everything is, and a full bladder also pushes organs so they are easily spotted.
It depends from the examined area. For an ultrasound of your pelvic, bladder or kidneys, your bladder must be REALLY chock-full. Its rather uncomfortable, but neccessary ;)
No. Urine is stored in the bladder until the bladder is full. The ureters are the tubes that carry the urine from the kidneys to be stored in the bladder. And then when the bladder is full, the urine travels through the urethra to outside of the body.
A person may only last 2 days if his or her urinary bladder is not well-functioning.
Oh yes, trust me! You have to drink tons of water until your bladder is very, very full, then hold it in until the exam is over. Then the doc squirs some icecold gel just above your lower abdomen and pushes hard into your chock-full bladder. Some US require to hold in breath for a few seconds (and full bladder too)... Ultrasound with full bladder=Not fun!
More common symptoms are pain in the bladder if its full, you feel going to the bathroom frequently than normal, or you can't hold even if your bladder is not full but it feels like full.
A full bladder triggers an urgency to urinate. If you don't urinate within a reasonable amount of time, the bladder can overfill and backflow to the kidneys, which can cause serious problems.
A completely full bladder is capable of holding approximately 1 liter of fluid … Ordinarily the urge to urinate occurs when the bladder contains about 200 ml of urine.
Usually it will partially empty itself against your will as nature's way to prevent it from exploding. But if you have a full bladder in a car accident or play contact sports with a full bladder - and a surprising number of people do - and you are struck in the pelvic area, it can burst upward through the dome into your pelvic cavity, causing a life threatening medical emergency.
