- Diabetic kidney disease, also called diabetic nephropathy, is kidney disease caused by diabetes.  - People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.  - At the onset of diabetes, blood flow into the kidneys increases, which may strain the glomeruli and lessen their ability to filter blood.  - Higher levels of blood glucose lead to the buildup of extra material in the glomeruli, which increases the force of the blood moving through the kidneys and creates stress in the glomeruli.  - Many people with diabetes can develop high blood pressure, another factor in the development of kidney disease. High blood pressure, also called hypertension, is an increase in the amount of force that blood places on blood vessels as it moves through the entire body.  - Diabetic kidney disease takes many years to develop.  - People with diabetic kidney disease do not have any symptoms in the early stages. As kidney disease progresses, a person can develop edema, or swelling. Edema happens when the kidneys cannot get rid of the extra fluid and salt in the body. Edema can occur in the legs, feet, or ankles and less often in the hands or face.  - Once kidney function decreases further, symptoms may include      - appetite loss    - nausea    - vomiting    - drowsiness, or feeling tired    - trouble concentrating    - sleep problems    - increased or decreased urination    - generalized itching or numbness    - dry skin    - headaches    - weight loss    - darkened skin    - muscle cramps    - shortness of breath    - chest pain    - People can prevent or slow the progression of diabetic kidney disease by      - taking medication to control high blood pressure    - managing blood glucose levels    - making changes in their eating, diet, and nutrition    - losing weight if they are overweight or obese    - getting regular physical activity
Simple kidney cysts are abnormal, fluid-filled sacs that form in the kidneys. Simple kidney cysts are different from the cysts that develop when a person has polycystic kidney disease (PKD), which is a genetic disorder. Simple kidney cysts do not enlarge the kidneys, replace their normal structure, or cause reduced kidney function like cysts do in people with PKD.
                
Simple kidney cysts are more common as people age. An estimated 25 percent of people 40 years of age and 50 percent of people 50 years of age have simple kidney cysts.1
The kidneys are two bean-shaped organs, each about the size of a fist. They are located near the middle of the back, just below the rib cage, one on each side of the spine. Every day, the two kidneys process about 200 quarts of blood to filter out about 1 to 2 quarts of urine, composed of waste products and extra water. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine until releasing it through urination.
Simple kidney cysts usually do not cause symptoms or harm the kidneys. In some cases, however, pain can occur between the ribs and hips when cysts enlarge and press on other organs. Sometimes cysts become infected, causing fever, pain, and tenderness. Simple kidney cysts are not thought to affect kidney function, but one study found an association between the presence of cysts and reduced kidney function in hospitalized people younger than 60 years of age.1 Some studies have found a relationship between simple kidney cysts and high blood pressure. For example, high blood pressure has improved in some people after a large cyst was drained. However, this relationship is not well understood.2
Most simple kidney cysts are found during imaging tests done for other reasons. When a cyst is found, the following imaging tests can be used to determine whether it is a simple kidney cyst or another, more serious condition. These imaging tests are performed at an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Ultrasound may also be performed in a health care providers office. Anesthesia is not needed though light sedation may be used for people with a fear of confined spaces who undergo magnetic resonance imaging (MRI).
                
- Ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. An abdominal ultrasound can create images of the entire urinary tract. The images can be used to distinguish harmless cysts from other problems.  - Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. CT scans can show cysts and tumors in the kidneys.  - MRI. MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include the injection of contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. Like CT scans, MRIs can show cysts and tumors.
Treatment is not needed for simple kidney cysts that do not cause any symptoms. Simple kidney cysts may be monitored with periodic ultrasounds.
                
Simple kidney cysts that are causing symptoms or blocking the flow of blood or urine through the kidney may need to be treated using a procedure called sclerotherapy. In sclerotherapy, the doctor punctures the cyst using a long needle inserted through the skin. Ultrasound is used to guide the needle to the cyst. The cyst is drained and then filled with a solution containing alcohol to make the kidney tissue harder. The procedure is usually performed on an outpatient basis with a local anesthetic.
                
If the cyst is large, surgery may be needed. Most surgeries can be performed using a laparoscopea special tool with a small, lighted video camera. The procedure is usually done under general anesthesia in a hospital. The surgeon drains the cyst and then removes or burns away its outer tissue. This type of surgery allows for a smaller incision and quicker recovery.

Talking about bladder control problems is not easy for some people. You may feel embarrassed to tell your doctor. But talking about the problem is the first step in finding an answer. Also, you can be sure your doctor has heard it all before. You will not shock or embarrass your doctor or nurse.
                

                
Medical History
                
You can prepare for your visit to the doctor's office by gathering the information your doctor will need to understand your problem. Make a list of the medicines you are taking. Include prescription medicines and those you buy over the counter, like aspirin or antacid. List the fluids you drink regularly, including sodas, coffee, tea, and alcohol. Tell the doctor how much of each drink you have in an average day.
                
Finding a Doctor
                
You will need to find a doctor who is skilled in helping women with urine leakage. If your primary doctor shrugs off your problem as normal aging, for example, ask for a referral to a specialist-a urogynecologist or a urologist who specializes in treating female urinary problems. You may need to be persistent, or you may need to look to organizations to help locate a doctor in your area. See For More Information for a list of organizations.
                
Make a note of any recent surgeries or illnesses you have had. Let the doctor know how many children you have had. These events may or may not be related to your bladder control problem.
                
Finally, keep track of the times when you have urine leakage. Note what you were doing at the time. Were you coughing, laughing, sneezing, or exercising? Did you have an uncontrollable urge to urinate when you heard running water?
                
You can use What Your Doctor Needs to Know (Item A) and Your Daily Bladder Diary (Item B) to prepare for your appointment.
                
Physical Exam
                
The doctor will give you a physical exam to look for any health issues that may be causing your bladder control problem. Checking your reflexes can show possible nerve damage. You will give a urine sample so the doctor can check for a urinary tract infection. For women, the exam may include a pelvic exam. Tests may also include taking an ultrasound picture of your bladder. Or the doctor may examine the inside of your bladder using a cystoscope, a long, thin tube that slides up into the bladder through the urethra.
                
Bladder Function Tests
                
Any medical test can be uncomfortable. Bladder testing may sound embarrassing, but the health professionals who perform the tests will try to make you feel comfortable and give you as much privacy as possible.
You have two kidneys. The kidneys are shaped like beans. Each kidney is about the size of a fist. They are located just below your ribcage, one on each side of your spine. Your kidneys filter your blood. Each kidney is made of 1 million little filters. During every minute of every day, these filters take out waste materials that can hurt you. They also take out extra fluid from your blood. The wastes and extra fluid make urine. The urine flows from your kidneys to your bladder through tubes called ureters.The bladder stores urine until you urinate. Then, urine leaves the body through a tube called the urethra.

Kidney failure means your kidneys no longer filter your blood well enough to keep you healthy. Failing kidneys do a poor job of removing wastes and extra fluid from your blood. Wastes and extra fluid begin to build up. The buildup of wastes can make you sick. You may have the following symptoms:
                
- ankle, face, or belly swelling  - stomach sickness  - throwing up  - loss of appetite  - loss of sense of taste  - feeling tired  - weakness  - confusion  - headaches
Hemodialysis is a treatment for kidney failure that is done in a center several times per week. Some people learn to do hemodialysis in their homes. Hemodialysis uses a machine to filter your blood when your kidneys are too sick to filter any more. With hemodialysis, your blood is filtered outside of your body. Unfiltered blood is removed from the body and flows to the dialyzer to be cleaned. Filtered blood flows back to the body. First, a dialysis nurse places two needles into your arm. A pump on the hemodialysis machine draws your blood through one of the needles into a tube. The tube takes the blood to a filter, called a dialyzer. Inside the dialyzer, your blood flows through thin fibers that are like straws. The wastes and extra fluid leave the blood through tiny holes in the fibers. Then, a different tube carries the filtered blood back to your body through the second needle. The hemodialysis machine throws out the wastes and extra fluid, just like how your body makes urine. Hemodialysis does not make the kidneys better. However, it may help you feel better by filtering your blood when your kidneys fail.
Peritoneal dialysis uses the lining of your belly to filter your blood inside your body. You can do peritoneal dialysis at home because it uses your body to filter. A doctor will place a soft tube called a catheter in your belly a few weeks before you start treatment. The catheter stays in your belly permanently.
                
The catheter lets you put a kind of salty water from a plastic bag into your belly. Then, you can move around and go about your day. While the salty water is inside your belly, it soaks up wastes and extra fluid from your body. After a few hours, you drain the salty water from your belly into a drain bag. The salty water removes wastes and extra fluid from your body. The salty water can be thrown away into a toilet or tub. Then you start over with a fresh bag of salty water. You will empty and fill your belly four to six times a day.
                
The salty water is always in your belly soaking up wastes and extra fluid. Peritoneal dialysis does not make the kidneys better. However, it may help you feel better by filtering your blood when your kidneys fail.
                

                
Is dialysis a cure for kidney failure?   No. Hemodialysis and peritoneal dialysis help you feel better and live longer; however, they do not cure kidney failure. Although people with kidney failure are now living longer than ever, over the years kidney disease can cause problems such as heart disease, bone disease, arthritis, nerve damage, infertility, and malnutrition. These problems wont go away with dialysis; however, doctors now have new and better ways to prevent or treat them. You should discuss these problems and their treatments with your doctor.
A kidney transplant places a healthy kidney from another person into your body. The kidney may come from someone who has just died. Your doctor will place your name on a waiting list for a kidney. A family member or friend might be able to give you a kidney. Then you dont have to wait.
                
Once it is placed inside your body, the new kidney takes over filtering your blood. The damaged kidneys usually stay where they are. The new kidney is placed in the front-lower abdomen, on one side of the bladder. Your body normally attacks anything that shouldnt be there, such as bacteria. The body will think the new kidney shouldnt be there. You will take medicines called immunosuppressants to keep your body from attacking the new kidney.

Conservative management means your doctors take care of you without dialysis or a transplant. The doctors may give you medicines that make you feel more comfortable. You can have conservative management in your home. You may want to go to a hospice, a special place where you receive nursing care. Some people choose conservative management when dialysis or a transplant would not help them live longer or would make them suffer longer. Without dialysis or a transplant, you may live for a few weeks or several months.
If you have kidney failure, learn about the treatments and think about which one best fits you. Talk with people who are on hemodialysis or peritoneal dialysis. Ask what is good and bad about each treatment. If you make a choice and find you dont like it, talk with your doctor about trying something else. Ask your doctor about the transplant waiting list and the medicines needed after a transplant. Talk with people who have had kidney transplants and ask how it has changed their lives.
                
If you plan to keep working, think about which treatment choice would make working easier. If spending time with family and friends means a lot to you, ask which treatment gives you the most free time. Find out which treatment will give you the best chance to be healthy and live longer.
                
If you are thinking about conservative management, you may wish to speak with your family, friends, doctor, or mental health counselor as you decide.
                
You can take control of your care by talking with your doctor. You may need time to get used to your new treatment. Kidney failure can make your life harder. Treatments can help improve your life.

Peyronies disease is a disorder in which scar tissue, called a plaque, forms in the penisthe male organ used for urination and sex. The plaque builds up inside the tissues of a thick, elastic membrane called the tunica albuginea. The most common area for the plaque is on the top or bottom of the penis. As the plaque builds up, the penis will curve or bend, which can cause painful erections. Curves in the penis can make sexual intercourse painful, difficult, or impossible. Peyronies disease begins with inflammation, or swelling, which can become a hard scar.
                
The plaque that develops in Peyronies disease is not the same plaque that can develop in a persons arteries. The plaque seen in Peyronies disease is benign, or noncancerous, and is not a tumor. Peyronies disease is not contagious or caused by any known transmittable disease.
                
Early researchers thought Peyronies disease was a form of impotence, now called erectile dysfunction (ED). ED happens when a man is unable to achieve or keep an erection firm enough for sexual intercourse. Some men with Peyronies disease may have ED. Usually men with Peyronies disease are referred to a urologista doctor who specializes in sexual and urinary problems.
Medical experts do not know the exact cause of Peyronies disease. Many believe that Peyronies disease may be the result of
                
- acute injury to the penis  - chronic, or repeated, injury to the penis  - autoimmune diseasea disorder in which the bodys immune system attacks the bodys own cells and organs
                
Injury to the Penis
                
Medical experts believe that hitting or bending the penis may injure the tissues inside. A man may injure the penis during sex, athletic activity, or an accident. Injury ruptures blood vessels, which leads to bleeding and swelling inside the layers of the tunica albuginea. Swelling inside the penis will block blood flow through the layers of tissue inside the penis. When the blood cant flow normally, clots can form and trap immune system cells. As the injury heals, the immune system cells may release substances that lead to the formation of too much scar tissue. The scar tissue builds up and forms a plaque inside the penis. The plaque reduces the elasticity of tissues and flexibility of the penis during erection, leading to curvature. The plaque may further harden because of calcificationthe process in which calcium builds up in body tissue.
                
Autoimmune Disease
                
Some medical experts believe that Peyronies disease may be part of an autoimmune disease. Normally, the immune system is the bodys way of protecting itself from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. Men who have autoimmune diseases may develop Peyronies disease when the immune system attacks cells in the penis. This can lead to inflammation in the penis and can cause scarring. Medical experts do not know what causes autoimmune diseases. Some of the autoimmune diseases associated with Peyronies disease affect connective tissues. Connective tissue is specialized tissue that supports, joins, or separates different types of tissues and organs of the body.
Researchers estimate that Peyronies disease may affect 1 to 23 percent of men between 40 and 70 years of age.1 However, the actual occurrence of Peyronies disease may be higher due to mens embarrassment and health care providers limited reporting.1 The disease is rare in young men, although it has been reported in men in their 30s.1 The chance of developing Peyronies disease increases with age.
The signs and symptoms of Peyronies disease may include
                
- hard lumps on one or more sides of the penis  - pain during sexual intercourse or during an erection  - a curve in the penis either with or without an erection  - narrowing or shortening of the penis  - ED
                
Symptoms of Peyronies disease range from mild to severe. Symptoms may develop slowly or appear quickly. In many cases, the pain decreases over time, although the curve in the penis may remain. In milder cases, symptoms may go away without causing a permanent curve.
