It is responsible for storing urine
The urge to urinate comes from stretch receptors that are activated when 300 to 400 ml of urine is retained within the bladder. As urine accumulates, the wrinkles flatten and the bladder wall thins as it stretches, allowing the bladder to store large amounts of urine without a significant increase in internal pressure. Urination is controlled by the pontine micturition center in the brainstem. The bladder is responsible for storing urine.
The urinary bladder is present in all mammals. It originates from the lower part of the allantoic pedicle, progressively obliterating the upper part of this pedicle to form the urachus.
The urinary bladder is located in the excavation of the pelvis. In front it is attached to the pubis, behind it borders the rectum, the upper part of the prostate and the seminal vesicles in men, and the vagina in women. Above it is covered by the parietal peritoneum that separates it from the abdominal cavity, and below it is bordered by the prostate in men and by the perineal musculature in women.
Where the urine comes out
If you have microscopic hematuria, you may not have symptoms. If you have gross hematuria, you will notice that your urine is pink, red or brown. This happens because the blood in your urine makes it a different color. If you have gross hematuria, you may also have blood clots in your urine, which can be painful.
If you notice that your urine is a different color than normal or if you have pain while you urinate, tell your health care provider. He or she can test you to find out the reason you have blood in your urine, the cause of the pain and the treatment that will be best for your situation.
Treatment for blood in the urine depends on the cause of the problem. For example, if you have blood in your urine from an infection, your doctor may recommend antibiotic medication. If you have blood in your urine for another reason, you may need a different type of treatment.

Your doctor will ask you about your signs and symptoms. He or she may press on your abdomen, sides, and back to check for pain. Your urine will be tested for bacteria that may be causing the infection. If you have urinary tract infections often, you may need other tests to find the cause.

How urine is formed
Bladder problems can affect people’s quality of life and cause other health problems. Your doctor can help you treat urinary incontinence by recommending a lifestyle change or a change in the amount of medication you normally take.
Men have a prostate gland that surrounds the opening of the bladder. As men age, their prostate enlarges. When the prostate becomes too large but is not cancerous, the man is said to have a condition known as enlarged prostate, or benign prostatic hyperplasia. Men with an enlarged prostate may have:
When the prostate becomes too large, it can compress the ureter, making it difficult to start urination. Also, urine flow may be slow or the bladder may not empty completely.
Nervous system problems are common causes of urinary incontinence. Urinary incontinence can occur when the brain does not communicate with the correct part of the urinary tract, usually the bladder, sphincters, or both, to do its job.
