Bladder Diseases

The bladder is a hollow organ in your lower abdomen that stores urine. Many conditions can affect your bladder. Some common ones are

  • Cystitis - inflammation of the bladder, often from an infection
  • Urinary incontinence - loss of bladder control
  • Overactive bladder - a condition in which the bladder squeezes urine out at the wrong time
  • Interstitial cystitis - a chronic problem that causes bladder pain and frequent, urgent urination
  • Bladder cancer

Doctors diagnose bladder diseases using different tests. These include urine tests, x-rays, and an examination of the bladder wall with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.

Kidney Stones

Also called: Nephrolithiasis

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

The following may be signs of kidney stones that need a doctor's help:

  • Extreme pain in your back or side that will not go away
  • Blood in your urine
  • Fever and chills
  • Vomiting
  • Urine that smells bad or looks cloudy
  • A burning feeling when you urinate

Your doctor will diagnose a kidney stone with urine, blood, and imaging tests.

If you have a stone that won't pass on its own, you may need treatment. It can be done with shock waves; with a scope inserted through the tube that carries urine out of the body, called the urethra; or with surgery.

Ureteral Disorders

Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters.

The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.

Sometimes the ureters can become blocked or injured. This can block the flow of urine to the bladder. If urine stands still or backs up the ureter, you may get a urinary tract infections.

Doctors diagnose problems with the ureters using different tests. These include urine tests, x-rays, and examination of the ureter with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
