Bladder Cancer

Bladder cancer is a disease that affects the bladder, the organ that stores urine. The most common type of cancer develops in the cells on the inner lining of the bladder wall. If the cancer spreads through the lining, it is considered an invasive cancer. The majority of cases of bladder cancer are diagnosed at an early stage when they are highly treatable. ...

Benign Prostatic Hyperplasia

Benign prostatic hyperplasia, also known as BPH, is an enlarged prostate that commonly causes urinary problems in men aged 50 years and older. It is a common condition that occurs as men age, causing the gland to press against the urethra and cause problems with urination. BPH may also be due to an excess of certain hormones in the body. ...

Bladder Prolapse

Bladder prolapse, also known as cystocele, is a common condition in women that involves a stretching or weakening of the pelvic floor muscles that support the bladder. Once this occurs, the bladder gradually sags into the vagina and may even protrude through its opening, causing urinary problems. Normally, in women, the bladder is held in position by supportive pelvic floor muscles and ligaments. When the muscles and tissues are stretched and weakened, the bladder can sag through the ligaments and into the vagina, resulting in bladder prolapse. ...

Bladder Stones

Bladder stones are hard, crystallized masses that form in the bladder. They can occur when the urine in the bladder becomes concentrated and causes the minerals and proteins it contains to crystalize. Bladder stones may be the result of the bladder not emptying completely during urination, which may be due to an enlarged prostate, nerve damage or recurring urinary tract infections. ...

Enlarged Prostate

The prostate is a golf ball-sized gland located under the bladder and in front of the rectum in men. While all of its functions are not known, the prostate adds fluid and nutrients to sperm to produce semen and allow the sperm to move more effectively. An enlarged prostate, also known as benign prostatic hyperplasia (BPH), is a common condition that occurs as men age. BPH causes the prostate to press against the urethra which results in urinary problems. It is believed that an enlarged prostate may be due to an excess of certain hormones in the body. ...

Erectile Dysfunction

Erectile dysfunction (ED) refers to the consistent inability to achieve or maintain an erection. For an erection to occur, a specific sequence of event needs to take place, allowing blood to enter the penis while restricting the outflow of blood. The pressure created by this "trapped" blood is what maintains an erection. If there is a consistent breakdown in any steps in the sequence, erectile dysfunction is the result. Erectile dysfunction may occur at any age, however, the occurrence of ED is increasingly common as a man ages. However, it should not be considered a natural part of aging. ...

Hydrocele

A hydrocele is a fluid-filled sac surrounding the testicle that results in swelling in the scrotum or groin. Common in newborns, in whom it usually disappears during the first year, it can also develop in older boys or men as a result of inflammation or injury. Between 1 and 2 percent of male infants have this problem and babies born prematurely are at increased risk. In men, hydroceles most often develop when patients are older than 40 years of age. Risk factors for hydrocele in adults include scrotal injury and infections, including sexually transmitted ones. ...

Interstitial Cystitis

Interstitial cystitis is a chronic inflammation or irritation of the bladder and the surrounding pelvic area. People who are diagnosed with interstitial cystitis may experience mild discomfort, pressure, tenderness, or intense pain in the bladder and pelvic area. Also known as painful bladder syndrome, interstitial cystitis most commonly affects women. ...

Kidney Cancer

Kidney cancer is characterized by a tumor that begins in the kidneys, the bean-shaped organs that help remove excess water and waste from the body through urine. Cancer that originates in the kidneys is common, with more than 60,000 people in the United States diagnosed with it each year.

Types of Kidney Cancer

There are several different types, classified by where they originate, of kidney cancer. The most common is renal-cell carcinoma, which begins in the small tubes found in the kidney. Typically beginning as a single mass, it can usually be identified before it spreads to other areas. ...

Kidney Stones

A kidney stone, also known as renal calculi or nephrolithiasis, is a hardened mass of mineral and acid salts that separates from the urine and travels through the urinary tract. The urine normally dilutes and dissolves these substances, but when the composition of urine is unbalanced, crystallized stones can form. Kidney stones are a common but painful urinary-tract disorder; men are more likely than women to get them. Kidney stones can cause severe pain, but usually do not cause any permanent damage to the urinary tract or body. ...

Low Testosterone in Men

Low testosterone, a form of hypogonadism, occurs when the body fails to produce an adequate supply of this hormone. This condition is more prevalent as men age, occurring in about 20 percent of men age 60 and older and increasing to as much as 50 percent in men age 80 and older. While testosterone is thought of as the male hormone, it is necessary for female functioning as well, and women may also suffer from low testosterone. ...

Neurogenic Bladder

Neurogenic bladder is a condition characterized by the loss of bladder function, which prevents people from effectively emptying the bladder. Normal bladder function involves a complex communication system between nerves and muscles that work together to tighten or release the bladder muscles and allow urine to be released. Neurogenic bladder is often the result of problems with nerves in the body that control how the bladder stores or empties urine. ...

Overactive Bladder

Overactive bladder (OAB), or urge incontinence, occurs when a person experiences a sudden and frequent urge to urinate that may also be accompanied by urine leakage. This often occurs because the bladder muscles contract at inappropriate times, regardless of how much urine has collected in the bladder. This may be caused by various underlying conditions or certain medications. It can happen to anyone at any age, although it seems to be most common in women and the elderly. ...

Prostate Cancer

Prostate cancer is one of the most common types of cancer in men. It affects the prostate, the gland located under the bladder and in front of the rectum that, among other functions, helps produce semen, and allows sperm to move effectively. Although prostate cancer can be life-threatening, it often spreads slowly and requires minimal treatment. When confined to the prostate gland, it can usually be treated effectively, making early detection crucial. ...

Prostate Cancer Screening

Prostate cancer is one of the most common types of cancer in men, affecting the gland located under the bladder and in front of the rectum. Once malignant cells develop in the prostate, they multiply much more quickly than normal cells. Because prostate cancer can metastasize and become life-threatening, prostate cancer screening, designed to detect the disease at its earliest, most treatable stages, is important. ...

STD Testing

A sexually transmitted disease (STD) is a disease or infection that is spread from one person to another through sexual contact. Most STDs are caused by bacteria, parasites or viruses, that are transmitted through contact with the genitals, skin, mouth, rectum, or bodily fluids. STDs can cause problems ranging from mild irritation to severe pain. Left untreated, some STDs can cause illness, cancer, infertility or harm to a fetus during pregnancy ...

Transurethral Microwave Thermotherapy

Transurethral microwave thermotherapy (TUMT) is a treatment for an enlarged prostate gland, also known as benign prostate hyperplasia (BPH). The prostate gland is part of a man's reproductive system. It is a walnut shaped organ located between the base of the bladder and the beginning of the penis. It surrounds the upper part of the urethra where it produces a fluid that is ejaculated with sperm. ...

Transurethral Needle Ablation

Transurethral needle ablation of the prostate, also known as TUNA, is a minimally invasive treatment for an enlarged prostate gland. The prostate gland is part of a man's reproductive system. An enlarged prostate, known as benign prostatic hyperplasia or BPH, is a common condition that occurs as men age, causing the gland to press against the urethra and cause problems with urination. In severe cases, BPH can completely block the ability to pass urine. ...

Urinary Incontinence

Urinary incontinence (UI) is the loss of bladder control. It is a common condition that involves the involuntary loss of urine. It may range in severity from occasionally leaking urine to a sudden urge to urinate that comes on very strongly. Although it is not usually a serious condition, UI can be embarrassing and affect a person's daily life. Urinary incontinence is most common in women, especially during and after pregnancy. It can, however, affect people of all ages. Being overweight or elderly may also increase the risk of urinary incontinence. ...

Urodynamic Testing

Urodynamic testing is a series of urological tests that may be performed to diagnose urinary problems. A physician may recommend urodynamic testing to investigate the cause of any urinary difficulties and assess the function of the bladder and its ability to store and empty urine. Urinary problems such as incontinence or an overactive bladder may be the result of several different conditions, including bladder infections, urethra or sphincter problems, enlarged prostate, nervous system malfunctions, or the side effects of medication. ...
