Urinary tract infection usually causes frequency and burning sensation on urination. It can cause discomfort in the rectum if the bladder is full and not emptying properly. In fact one of the causes of infection can be large volume of residual urine due to incomplete emptying of the bladder which can be easily detected with a renal tract ultrasound examination
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.
visceral sensory cortex
The function of the urinary bladder is to act as a reservoir of urine. The kidneys filter the blood of waste products and the urine produced trickles down the two tubes called ureters which open in the bladder. Once the bladder is full, stretch receptors convey the sensation and creates a desire and urge to pass urine to empty the bladder.
Why does a full bladder cause headaches
You have the sense to urinate when the nerves on the bladder wall feel pressure. When an animal has a blockage and the bladder becomes full and distended the bladder then stretches. When the blockage is removed the bladder has now lost some of it's ability o contract to normal size thus taking away some of the sensation of the need to urinate. This causes the bladder to only partially express during urination leaving urine in the bladder. This could lead to bacterial infections due to standing urine in the bladder.
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.
The bladder's main function is to store and release urine. Nerves in the bladder tell you when it is time to urinate (empty your bladder). As the bladder first fills with urine, you may notice a feeling that you need to urinate. The sensation to urinate becomes stronger as the bladder continues to fill and reaches its limit. At that point, nerves from the bladder send a message to the brain that the bladder is full, and your urge to empty your bladder intensifies.
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.
