Fibroid tumors of the uterus are same common. For the majority of women symptoms are minor or nonexistent.(1) In approximately 40% of women however, fibroids can cause an enlargement of the uterus, abnormal uterine bleeding, pelvic pain, and infertility.(2) Clinical and autopsy studies display that the incidence of fibroid tumors in women older than 35 years of age is 20% to 40%(3) Of all the hysterectomies performed in the United States, 33% are performed to do away with enlarging fibroids.(4)

a great deal effort has been expended to cause to grow more efficient treatment modalities with les morbidity and more rapid regaining than hysterectomies. Particular attention has been given to minimally invasive approaches, which, until newly were limited to hysteroscopic and laparoscopic surgery Uterine artery embolization (UAE), used as pressing necessity therapy for pelvic hemorrhage, lately has been introduced as the primary treatment for symptomatic uterine fibroids.(5)

THE FEMALE REPRODUCTIVE SYSTEM

The uterus is a pear-shaped organ located between the bladder and the lower intestine. It consists of sum of two units parts--the body and the cervix. When a woman is not pregnant, the material part of the uterus is about the size of a fist and its interior walls are collapsed. The cervix comprises the lower third of the uterus. It render free of accesss into the vagina allowing menstrual family to flow out of the uterus. The fallopian tubes lead facing each side of the upper carcass of the uterus, and the ovaries lie near the [i]finale[/i] of each tube. The inner lining of the uterus is called the endometrium. During pregnancy, the endometrium thickens and supports the growing fetus. During a normal menstrual period if pregnancy does not appear the endometrium is shed as menstrual melt Six key hormones serve as chemical emissarys that regulate the female reproductive body The hypothalamus first releases gonadotropin-releasing hormone (GnRH) This chemical stimulates the pituitary gland to give rise to follicle-stimulating hormone (FSH) and luteinizing hormone (LH) The ovaries separate estrogen, progesterone, and testosterone.(6) Estrogen causes the endometrial lining to be augmented in preparation for a pregnancy during the harry maturation phase of the reproductive revolution of time and, at peak levels, stimulates the release of LH Follicle-stimulating hormone causes the push to mature, and LH stimulates the egg's release. Progesterone is produc from the cells of the unoccupied egg follicle, and it causes the endometrium to increase in thickness. If the harass is not fertilized and there is no pregnancy, progesterone evens drop, causing the uterus to shed its endometrial lining.(7)

UTERINE FIBROIDS

Uterine fibroids are nodules of undisturbed muscle cells and fibrous connective tissue that evolve within the wall of the uterus. Another bound for uterine fibroids is uterine leiomyomata.(8) Size of uterine fibroids can vary fiord that of a pinhead to larger than a melon Fibroid weights of more than 20 lb have been reported.(9)

Fibroids are classified into three exemplars including

* intramural (ie, putting outs within the wall of the uterus),

* subserosal or subserous (ie, growings projecting into the uterine cavity), and

* submucosal or submucous (ie, growings projecting toward the outer surface of the uterus) (Figure 1)

The initial cause of fibroid disentanglement is unknown; however, estrogen appears to play a central role(10) rife research indicates that progesterone also contributes to fibroid formation. A substance called basic fibroblast growing factor (bFGF) also may be a contributing factor. Basic fibroblast shooting factor regulates angiogenesis, a proces that causes just discovered blood vessels to grow from preexisting singles The production of this substance is destroyed during the premenstrual phase in women without fibroids yet not in women who have them, thus suggesting that overactivity of bFGF may terminate in excess production of life-blood vessel clusters and cause the development of fibroids. (11)

The majority of fibroids come to pass in women of reproductive age and are diagnosed in African-American women pair to three times more at short intervals than in Caucasian women. Menarche before the age of 12 which defers the time a woman is make liableed to estrogen, may be a risk factor for fibroid progress to maturity Obesity also can raise estrogen on a levels Women who have never been pregnant are at higher risk for fibroids than women who have had children, and risk decreases with multiparity. Women who are sedentary also are at greater risk.(12) Fibroids are the most numerous frequently diagnosed benign tumor of the female pelvis.(13)

SYMPTOMS

Many of the symptoms experienced are related to the size, location, and number of fibroids. Symptoms may include

* heavy or lengthened menstrual periods, which can be the effect in anemia;

* pelvic pain or pressure;

* pain during sexual intercourse;

* bladder hurry causing the urge to urinate frequently;

* constipation to be ascribed to pressure on the colon; and

* pain in the back, flank, or leg befitting to pressure on nerves.(14)
