Transcutaneous Electrical Nerve Stimulation (TENS)

Discusses transcutaneous electrical nerve stimulation (TENS), a therapy that uses low-voltage electrical current for pain relief. Covers TENS treatment for different illnesses and conditions such as muscle, joint, or bone problems.

Transcutaneous electrical nerve stimulation (TENS)

Transcutaneous electrical nerve stimulation (TENS) is a therapy that uses mild electrical current to treat pain. Current is delivered through small pieces of material that conduct electricity (electrodes). These are placed on the skin near the source of pain. When the current is delivered, some people experience less...

Transcutaneous oxygen and carbon dioxide monitor

A transcutaneous oxygen and carbon dioxide monitor is a device that measures the oxygen and carbon dioxide levels in a baby's blood. This test does not require a doctor or a nurse to take a blood sample from the baby. The monitor is connected to the baby by a lead (wire), the end of which has a small circle that is held...

Transesophageal Echocardiogram

A transesophageal echocardiogram is a test to help your doctor look at the inside of your heart. A small device called a transducer directs sound waves toward your heart. The sound waves make a picture of the heart's valves and chambers. Your doctor may do this test to look for certain types of heart disease. Or it may...

Transformation zone of the cervix

The cervix contains two kinds of cells: rectangular columnar cells and flat, scale-like squamous cells. Columnar cells are constantly changing into squamous cells in an area of the cervix called the transformation (transitional) zone. The transformation zone is an area of changing cells, and it is the most common place...

Transient ischemic attack (TIA)

During a transient ischemic attack (TIA), blood flow to part of the brain is temporarily blocked or reduced, often by a blood clot. This causes the same symptoms as a stroke, but after a few minutes or more, blood flow is restored and the symptoms go away.

Transient Ischemic Attack (TIA)

Discusses transient ischemic attack (TIA), sometimes called a mini-stroke. Covers causes, including blood clot as a result of atherosclerosis. Looks at treatment with medicines, surgery, and lifestyle changes. Discusses prevention steps.

Transient ischemic attack (TIA)

A transient ischemic attack (TIA) happens when blood flow to part of the brain is stopped for a short time. This can cause stroke symptoms that may last for at least a few minutes. But unlike a stroke, a TIA doesn't cause lasting brain damage. A TIA is a warning that you may have a stroke in the future. Early treatment...

Transitional Milk

Transitional milk is high-protein breast milk that a woman produces about 3 to 6 days after her baby is born. A woman's breasts are stimulated to produce transitional milk by breastfeeding her baby regularly. The breasts make transitional milk after a period of producing colostrum, which is a thick, sticky, yellowish...

Transjugular Intrahepatic Portosystemic Shunt (TIPS)

TIPS is a procedure in which a stent is placed to join two veins in a damaged liver. One vein carries blood to the liver (portal vein). The other vein goes from the liver to the heart (hepatic vein). TIPS forms a channel that allows some of the blood to bypass the liver.

Transplant rejection

A transplant rejection is the body's destruction of a newly introduced organ or tissue. A person's immune system does not recognize the cells of the transplanted material, which triggers it into action to kill the transplanted tissues. The immune system's response eventually makes the organ or tissue unable to function...

Transposition of the great vessels

In transposition of the great vessels, the major blood vessels attached to the heart—the aorta and the pulmonary artery—are reversed. This reversal results in the blood going to the wrong places. This leads to low oxygen levels in the body. The aorta, which normally carries oxygen-rich blood from the left side of the...

Transrectal Prostate Biopsy

A transrectal prostate biopsy is usually done with a device that contains a spring-loaded needle. The needle enters the prostate gland and removes a tissue sample quickly.

Transrectal ultrasound

A transrectal ultrasound (TRUS) is a procedure in which a device is placed into the rectum to help a doctor locate abnormal tissue around the prostate gland or to collect a sample of tissue to examine (biopsy). An ultrasound uses sound waves that bounce off solid structures. This type of ultrasound creates a picture of...

Transrectal Ultrasound

A transrectal ultrasound is used to look at the prostate gland and other pelvic organs in men. A thin probe called a transducer is covered with a lubricated sheath similar to a condom. The transducer is then gently put into the rectum. The transducer sound waves make a picture on a TV screen (monitor).

Transsphenoidal adenomectomy

Transsphenoidal adenomectomy is a type of surgery that may be used to remove a tumor (adenoma) of the pituitary gland, which lies at the bottom of the brain. Using a special microscope, the surgeon reaches the pituitary gland by threading tiny instruments through a person's nostril or into a small opening made in the...

Transthoracic Echocardiogram

An echocardiogram (also called an echo) uses sound waves to make an image of your heart. A device called a transducer sends sound waves that echo off your heart and back to the transducer. These echoes are turned into moving pictures of your heart that can be seen on a video screen. In a transthoracic echocardiogram...

Transurethral Incision of the Prostate (TUIP) for Benign Prostatic Hyperplasia

You will likely stay in the hospital for 1 to 3 days after surgery. Most people can go back to work or their usual routine in about 3 to 5 weeks. But it can take longer to fully recover. A thin, flexible tube called a catheter usually is left in your bladder to drain your urine for 1 to 2 weeks. Your doctor will give...

Transurethral Microwave Therapy (TUMT) for Benign Prostatic Hyperplasia

In transurethral microwave therapy (TUMT), an instrument (called an antenna) that sends out microwave energy is inserted through the urethra to a location inside the prostate. Microwave energy is then used to heat the inside of the prostate. Cooling fluid is circulated around the microwave antenna to prevent heat from...

Transurethral Resection of the Bladder

Transurethral resection of the bladder is a surgery to remove abnormal tissue (tumor) from the bladder through the urethra. It is also called transurethral resection of bladder tumor, or TURBT. A tumor in the bladder may be benign (not cancer) or malignant (cancer). This surgery uses a special tool to find and remove a...

Transurethral resection of the prostate (TURP)

Transurethral resection of the prostate (TURP) is surgery that removes some tissue from inside the prostate gland. It is done to treat prostate enlargement (called benign prostatic hyperplasia, or BPH). A doctor inserts a special instrument through the urethra to remove part of the inside of the prostate. A wire loop...

Transurethral Therapy for Erection Problems

An applicator is used to insert a small pellet of medicine inside the opening at the end of the penis. The pellet dissolves, and the medicine causes an erection. The erection can last for at least 30 minutes.

Transvaginal ultrasound

Transvaginal ultrasound is a test that uses reflected sound waves to produce a picture of the reproductive organs and other structures inside the pelvis. It does not use X-rays or other types of radiation. For a transvaginal ultrasound, an ultrasound wand (transducer) is placed in the vagina. The transducer emits...

Transvaginal Ultrasound

A transvaginal ultrasound is used to look at the pelvic organs in women. A thin probe called a transducer is covered with a lubricated sheath similar to a condom. The transducer is then gently put into the vagina. The transducer sound waves make a picture on a TV screen (monitor).
