  • Foley catheter - a catheter with an inflatable balloon tip for retention in the bladder.
  • GnRH - gonadotropin-releasing hormone; a hormone that stimulates part of the pituitary to release hormones that affect the reproductive system.
  • GnRH agonists - chemical substances with the same effect typically produced by GnRH.
  • Gonadotropin – a hormone whose release is stimulated by GnRH; two (Luteinizing Hormone (LH) and Follicle Stimulating hormone (FSH) are secreted by the pituitary gland in a cyclic fashion that governs the menstrual cycle; a third (Human Chorionic Gonadotropin, or hCG) it is secreted by the placenta during pregnancy, is found in the urine and blood of pregnant women, and used medically to induce ovulation.
  • Groin – the fold or depression where the lower abdomen meets the inner part of the thigh.
  • Hysterectomy – surgical removal of the uterus
  • Incision – a cut or wound of body tissue made especially in surgery.
  • Intramural (fibroids) – fibroid tumors located within the muscular walls of the uterus.
  • IUD – intrauterine device; a device inserted and left in the uterus to prevent conception.
  • IV line — an apparats used to administer a fluid (medication, blood, or nutrients) intravenously.
  • Laparoscopic myomectomy - surgical excision (cutting out) of a fibroid, with the use of a viewing device inserted through an incision in the abdominal wall to see inside the body cavity.
  • Leiomyoma (plural: leiomyomata) - a benign tumor, as a fibroid, consisting of smooth muscle fibers.
  • Medical history - a patient’s health history: diseases, surgeries, drug sensitivity, etc.
  • Menopause - the natural ending of menstrual periods occurring usually between 45 and 55; the time in a woman’s life when this occurs and ovarian function decreases; menopause is also caused by surgical removal of the ovaries.
  • Menstrual - relatng to menstruation or a woman’s monthly periods
  • Miscarriage - spontaneous expulsion of a fetus before it can survive, especially between the 12th and 28th weeks of pregnancy.
  • MRgFUS - Magnetic Resonance (imaging) guided Focused Ultrasound Surgery.
  • Myomectomy - surgical removal (excision) of a fibroid.
  • Necrosis - tissue death; especially death of a portion of tissue affected by loss of blood supply, burning, or local injury.
  • Noninvasive - not involving entry into the body by incision or inserting a medical instrument.
  • Oral contraceptive - birth control pill.
  • Osteoporosis - a condition that affects especially older women, and involves decreased bone mass and increased brittleness; osteoporosis often results from the reduction in female hormone levels at menopause.
  • Outpatient procedure - a medical procedure in which a patient is not hospitalized overnight, but visits a hospital, clinic, or associated facility for diagnosis or treatment.
  • Pap smear - a test for the early detection of cancer, especially of the uterine cervix.
  • Pedunculated fibroids - fibroids growing on or being attached to the uterus by a narrow stalk.
  • Pelvic region - the region at the lower extent of the abdomen, surrounded by the hip bones and “tail bone” (sacrum and coccyx); the reproductive organs, urinary bladder, and lower colon and rectum are located here.
  • Postmenopausal - occurring after menopause.
  • Progesterone - a female steroid hormone that prepares the uterine lining for pregnancy and maintains pregnancy when it occurs; a synthetic steroid with similar functions.
  • Radiologist - a physician specializing in the use of radiant energy for diagnosis and therapy.

  • Sonication - a period of time (usually 20-30 seconds) when the focused ultrasound beam is heating a small area of tissue to destroy it
  • Submucosal (fibroids) - fibroids located directly beneath the mucous membrane lining the uterine cavity; mucous membranes are rich in mucous glands, and line body passages that communicate with the exterior (as in the digestive, respiratory, and reproductive tracts).
  • Subserosal (fibroids) - fibroids located under the serous membrane that covers the outside of the uterus; serous membranes line body cavities or enclose organs contained in these cavities.
  • Supracervical hysterectomy - a hysterectomy in which the uterine cervix is not removed.
  • Symptomatic - showing or experiencing symptoms.
  • Symptom - subjective evidence of disease observed or experienced by the patient.
  • Thermal ablation - to remove or destroy by the use of intense heat.
  • UAE (uterine artery embolization) — process in which pellets are introduced into the circulatory system to block branches of the uterine artery (such as those carrying blood to uterine fibroids, in which case the fibroid may shrink).
  • Ultrasound - sound vibrations with frequencies above the range of human hearing; the use of these sound vibrations for diagnostic or therapeutic purposes.
  • Urinary bladder - the sac that receives urine from the kidneys and discharges it by urination; located in the pelvic region in front of the rectum.
  • Urination - the act of urinating; passing water.
  • Uterine - related to, occurring in, or part of the uterus.
  • Uterus - the female organ that contains and nourishes the young during development (the womb); its thick walls consist of an outer serous layer, a thick middle layer of smooth muscle, and an inner mucous layer; during pregnancy the uterus undergoes a great increase in size.
