  • Kidney Disorders

    Detailed information on kidney disorders

  • Overview of Kidney Disorders

    Detailed information on kidney conditions, including kidney function, nephrology, kidney problem causes, kidney disease symptoms, and 1 labeled, full-color anatomical illustration

  • Renal Vascular Disease
    Renal vascular disease affects the blood flow into and out of the kidneys. It may cause kidney damage, kidney failure, and high blood pressure.
  • Analgesic Nephropathy
    Taking one or a mix of painkiller medicines daily over a long time may cause chronic kidney problems. This is called analgesic nephropathy. Painkillers that combine 2 or more medicines (such as, aspirin and acetaminophen together) with caffeine or codeine are the most likely to harm the kidneys.
  • Anatomy of the Urinary System

    Detailed anatomical description of the urinary system, including simple definitions and labeled, full-color illustrations

  • Bladder Cancer

    Detailed information on bladder cancer, including symptoms, types, causes, risk factors, prevention, diagnosis, and treatment

  • Benign Prostatic Hyperplasia (BPH)
    Benign prostatic hyperplasia (BPH) is also called benign prostatic hypertrophy. It’s when the prostate gland becomes very large and may cause problems passing urine. BPH is not cancer, and is a common part of aging.
  • Kidney Cancer

    Detailed information on renal cell cancer, the most common type of kidney cancer, including symptoms, causes, diagnosis, and treatment

  • Cystocele
    When the wall between the bladder and the vagina weakens, the bladder may drop or sag into the vagina. This disorder in women is called cystocele.
  • Urogenital Disorders

    Detailed information on the most common urogenital disorders, including bladder cancer, cystocele (fallen bladder), hematuria, blood in the urine, impotence, erectile dysfunction, interstitial cystitis, male factor infertility, prostate disease, benign prostatic hyperplasia, BPH, prostate cancer, urinary incontinence, urinary tract infection, vesicoureteral reflux

  • Kidney Failure
    Kidney failure occurs when damage results in loss of normal kidney function. It may also be called end stage renal disease (ESRD).
  • Glomerulosclerosis
    Glomerulosclerosis is scarring in the tiny blood vessels in the kidneys called the glomeruli. These are the tiny units in the kidneys that filter urine from the blood.
  • Glomerulonephritis
    When the kidneys' filters (glomeruli) become inflamed and scarred it is called glomerulonephritis. The kidney’s slowly lose their ability to remove wastes and excess fluid from the blood to make urine.
  • Goodpasture Syndrome
    Goodpasture syndrome is a rare autoimmune disease that affects the lungs and kidneys. Normally, the immune system makes antibodies to fight off germs. With Goodpasture syndrome, however, the immune system mistakenly makes antibodies that attack the lungs and kidneys. This condition can quickly progress to glomerulonephritis and kidney failure.
  • Blood in the Urine
    Blood in the urine means there are red blood cells (RBCs) in the urine. Often, the urine looks normal to the naked eye. But when checked under a microscope, it contains a high number of red blood cells. In some cases, the urine is pink, red, or the color of tea, which you can see without a microscope.
  • Hemolytic Uremic Syndrome

    Detailed information on hemolytic uremic syndrome, including cause, progression, treatment, and statistics

  • Immunoglobulin A (IgA) Nephropathy
    IgA nephropathy is a chronic kidney disease. It progresses over 10 to 20 years, and can lead to end-stage renal disease. It is caused by deposits of the protein immunoglobulin A (IgA) inside the filters (glomeruli) in the kidney. These glomeruli normally filter waste and excess water from the blood and send them to the bladder as urine. However, the IgA protein prevents this filtering process.
  • Impotence/Erectile Dysfunction
    Erectile dysfunction (ED) or impotence means you can’t get an erection. It can also mean you are dissatisfied with the size or hardness of your erections, or how long your erections last.

    Detailed information on urology, the branch of medicine concerned with the urinary tract in both genders, and with the genital tract or reproductive system in the male

  • Male Infertility
    Infertility is a disease of the reproductive system. It makes a person unable to have children. It can affect a man, a woman, or both. Male infertility means that a man has a problem with his reproductive system. It means you cannot start a pregnancy with your female partner.
  • Interstitial Cystitis
    Interstitial cystitis (IC) is an inflamed or irritated bladder wall. It can lead to scarring and stiffening of the bladder. The bladder can’t hold as much urine as it did in the past. It is a chronic disorder.
  • Nephrotic Syndrome
    Nephrotic syndrome causes scarring or damage to the filtering part of the kidneys (glomeruli). This causes too much protein to be lost from the blood into the urine.
  • Neurogenic Bladder
    The muscles and nerves of the urinary system work together to hold and release urine at the right time. Nerves carry messages between the bladder and the spinal cord and brain. The messages tell the muscles of the bladder to either tighten or release. In neurogenic bladder, these nerves don’t work the way they should.

  • Peyronie's Disease
    Peyronie's disease causes hard, flat plaque to form under the skin on the tissue of the penis. The plaque often starts as an inflammation that may develop into scar tissue. It can cause pain and a sharp curve in the penis during erections.
  • Polycystic Kidney Disease

    Detailed information on the different types of polycystic kidney disease, including autosomal dominant polycystic kidney disease, autosomal recessive polycystic kidney disease, and acquired cystic kidney disease

    Detailed information on the most common urogenital disorders, including analgesic nephropathy, bladder cancer, cystocele (fallen bladder), end stage renal disease, glomerulonephritis, glomerulosclerosis, goodpasture syndrome, hematuria (blood in the urine

  • Kidney Stones
    A kidney stone is a hard, pebble-like deposit that forms in the kidney. It may be as small as a grain of sand or as large as a pearl. Some are as big as golf balls. A stone may be smooth, irregular in shape, or jagged. Most are yellow or brown in color. There are different types of kidney stones.
  • Kidney Transplantation

  • Urinary Tract Infections or UTIs
    Urinary tract infections or UTIs are infections in any part of the urinary tract. They are a common health problem that affects millions of people each year. Women are especially prone to UTIs.
  • Vesicoureteral Reflux (VUR)

    Detailed information on vesicoureteral reflux, including cause, symptom, diagnosis, and treatment

  • Urinary Incontinence

    Urinary incontinence is the loss of urine control, or the inability to hold your urine until you can reach a bathroom.

  • Bladder and Bowel Dysfunction

    Bladder dysfunction and bowel dysfunction refer to problems with urinating and passing stools. These may lead to the unwanted passage of urine or stool, called urinary or fecal incontinence.
