The bladder is a hollow organ in your lower abdomen that stores urine. Bladder cancer occurs in the lining of the bladder. It is the sixth most common type of cancer in the United States.

Symptoms include:

• Blood in your urine
• A frequent urge to urinate
• Pain when you urinate
• Low back pain

Risk factors for developing bladder cancer include smoking and exposure to certain chemicals in the workplace. People with a family history of bladder cancer or who are older, White, or male have a higher risk.

Treatments for bladder cancer include surgery, radiation therapy, chemotherapy, and biologic therapy. Biologic therapy boosts your body's own ability to fight cancer.

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.

You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. Your kidneys filter and clean your blood, taking out waste products and making urine. Kidney tests check to see how well your kidneys are working. They include blood, urine, and imaging tests.

Early kidney disease usually does not have signs or symptoms. Testing is the only way to know how your kidneys are doing. It is important for you to get checked for kidney disease if you have the key risk factors - diabetes, high blood pressure, heart disease, or a family history of kidney failure.

Specific kidney tests include:

• Glomerular filtration rate (GFR) - one of the most common blood tests to check for chronic kidney disease. It tells how well your kidneys are filtering.
• Creatinine blood and urine tests - check the levels of creatinine, a waste product that your kidneys remove from your blood
• Albumin urine test - checks for albumin, a protein that can pass into the urine if the kidneys are damaged
• Imaging tests, such as an ultrasound - provide pictures of the kidneys. The pictures help the health care provider see the size and shape of the kidneys, and check for anything unusual.
• Kidney biopsy - a procedure that involves taking a small piece of kidney tissue for examination with a microscope. It checks for the cause of kidney disease and how damaged your kidneys are.

X-rays are a painless medical imaging test. They send a small amount of radiation through your body to create pictures of bones and organs.

X-rays are a type of electromagnetic radiation. They create images in shades of black, white, and gray because different tissues absorb radiation differently. Bones absorb the most radiation and appear white. Fat and other soft tissues absorb less and appear gray. Air absorbs the least radiation, so areas like the lungs appear black.

The image is recorded on film or sent to a computer. Health care providers use x-rays to find health problems and to check how well certain treatments are working.

X-rays are commonly used to check for fractures (broken bones). They are also used for other purposes. For example, chest x-rays can detect pneumonia. Mammograms use x-rays to look for breast cancer. X-rays are also used as part of other imaging tests, such as CT scans.

In most cases, little or no preparation is needed. You may be asked to wear a lead apron to protect certain parts of your body. You may also be asked to remove jewelry or other items that could affect the image.

The amount of radiation from an x-ray is small. For example, the radiation from a chest x-ray is about the same as the natural radiation you are exposed to from the environment over about 10 days.

Always tell your provider if you are pregnant or think you may be pregnant.

Depending on the part of your body being examined, you may be asked to stand, sit, or lie down. You will need to stay still for a short time while the image is taken.

After an x-ray, you can return to normal activities right away. A specialist called a radiologist reviews the images and shares the results with your provider.

You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. The tubes inside filter and clean your blood, taking out waste products and making urine. Kidney cancer forms in the lining of tiny tubes inside your kidneys.

Kidney cancer becomes more likely as you age. Risk factors include smoking, having certain genetic conditions, and misusing pain medicines for a long time.

You may have no symptoms at first. They may appear as the cancer grows. See your health care provider if you notice:

• Blood in your urine
• A lump in your abdomen
• Weight loss for no reason
• Pain in your side that does not go away
• Loss of appetite

Tests to diagnose kidney cancer include blood, urine, and imaging tests. You may also have a biopsy.

Treatment depends on your age, your overall health and how advanced the cancer is. It might include surgery, chemotherapy, or radiation, biologic, or targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells.

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.

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 infection.

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.
