Learning About Your Urinary System

Female and male urinary systems

What does your urinary system do?

The urinary system is the network of organs and tubes that process and carry urine out of the body. The kidneys and ureters are called the upper urinary tract. The bladder and urethra are called the lower urinary tract.

Your kidneys filter waste products and water from the blood to make urine. They also keep the proper balance of fluids and chemicals your body needs to work as it should.

Tubes called ureters carry urine from the kidneys to the bladder. The bladder stores the urine. When the bladder is full, the urine leaves the body through another thin tube, called the urethra.

What problems can happen with this system?

Urinary problems include:

  • A urinary tract infection, or UTI. This is an infection anywhere between the kidneys and the urethra.
  • Kidney stones. These are tiny stones that form in the kidneys. They can cause blood in the urine and severe pain.
  • Trouble urinating or not being able to urinate. This is often caused by an enlarged prostate in men.
  • Incontinence. This means you have trouble controlling the release of urine.

Common symptoms of a urinary problem include:

  • A burning feeling when you urinate. This is the most common symptom of a UTI.
  • An urgent need to urinate.
  • Blood in the urine. Your urine may look red, brown, or pink.
  • Incontinence.

Treatment for urinary problems depends on the cause. Your doctor may treat an infection with an antibiotic. Or you may need a procedure to help a kidney stone pass.

How can you prevent urinary problems?

  • Drink plenty of fluids, enough so that your urine is light yellow or clear like water. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
  • Urinate when you need to.

Tips for women

  • Urinate right after you have sex.
  • Change sanitary pads often.
  • Avoid douches, bubble baths, feminine hygiene sprays, and other feminine hygiene products that have deodorants.
  • After you use the toilet, wipe from front to back.
