My brother can hold in his bladder 1300ml too and he has a huge bladder so yes its large
Added: the normal, healthy bladder holds between 300 and 800 ml. So, yes, 1300 is way, way too much. Your brother is damaging his bladder.
1300ml
No
Why does a full bladder cause headaches
1300ml
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.
1300ml
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.
1.3L = 1300mL @1000mL per liter.
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!
No, your brain is one of the larger organs. If your bladder was that big you would probably have some sort of disorder.
