laparoscopic lymphadenectomy - the removal of pelvic lymph nodes with a laparoscope.
lymph nodes - small glands located in many areas of the body that help defend the body against harmful foreign particles.
lymphadenectomy - a procedure in which lymph nodes are taken from the body for purposes of diagnosing or staging cancer.
lymphangiogram - an x-ray that uses a special dye to determine whether cancer has spread to the lymph nodes.
magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radio-frequencies, and a computer to produce detailed images of organs and structures within the body.
malignant tumor - a mass of cancer cells that may invade surrounding tissues or spread to distant areas of the body.
metastasis - the spread of cancer cells to distant areas of the body by way of the lymph system or bloodstream.
nerve sparing technique - a surgical technique during a radial prostatectomy where one or both of the neurovascular bundles controlling erections are spared.
orchiectomy (Also called castration.) - the surgical removal of the testicles.
overflow incontinence - leakage of urine that occurs when the quantity of urine produced exceeds the bladder's capacity to hold it.
palliative treatment - therapy that relieves symptoms, such as pain, but does not alter the course of the disease. Its primary purpose is to improve the quality of life.
pelvic node dissection - lymph nodes near the prostate are removed to determine if cancer has spread.
prognosis - a prediction of the course of the disease; the future prospects for the patient.
prostatalgia - pain in the prostate gland.
prostate - a sex gland in men. It is about the size of a walnut and surrounds the neck of the bladder and urethra, the tube that carries urine from the bladder. It is partly muscular and partly glandular, with ducts opening into the prostatic portion of the urethra. It is made up of three lobes, a center lobe with one lobe on each side.
prostate acid phosphatase (PAP) - an enzyme produced by the prostate that is elevated in some patients when prostate cancer has spread beyond the prostate.
prostatectomy - surgical procedure for the partial or complete removal of the prostate.
prostate-specific antigen (PSA) - an antigen made by the prostate gland and found in the blood; may indicate cancer in the prostate gland.

stress incontinence - the most common type of incontinence that involves the leakage of urine during exercise, coughing, sneezing, laughing, lifting heavy objects, or other body movements that put pressure on the bladder.
testosterone - male sex hormone produced mostly by the testicles, although a small amount is made by the adrenal glands.
trans-rectal ultrasound of the prostate - a test using sound wave echoes to create an image of an organ or gland to visually inspect for abnormal conditions, such as gland enlargement, nodules, penetration of tumor through capsule of the gland, and/or invasion of seminal vesicles. It may also be used for guidance of needle biopsies of the prostate gland and guiding the nitrogen probes in cryosurgery.
transurethral surgery - surgery in which no external incision is needed. For prostate transurethral surgery, the surgeon reaches the prostate by inserting an instrument through the urethra. See below for different types of transurethral surgery.
transurethral hyperthermia - an investigative procedure that uses heat, usually provided by microwaves, to shrink the prostate.
