Uterine fibroid

Fibroids  are benign monoclonal tumors of smooth muscle cells that grow from the muscle wall of intra-abdominal organs. In gynecology we talk about uterine fibroids or myoma uteri (the formation grows out of the myometrium), in the digestive tract it is a fibroid of the smooth muscle of the GIT wall.

We most often encounter fibroids in gynecology - uterine fibroids. Fibroids are the most common benign body in the female genital tract. The prevalence of uterine fibroids is 20-30% in women under 30 years and 50% in women over 30 years.

Uterine fibroids reach a size of 1 cm to (exceptionally) several decimetres. They can occur solitarily, sometimes they are multiple - then we talk about myomatosis.

Fibroids are usually benign. Malignant reversal of uterine fibroids is rare.

Myoma is a hormone-dependent tumor - it contains hormone receptors - after menopause or after treatment with GnRH, fibroid analogues regress.

Risk factors
Risk factors for uterine fibroids include genetic predisposition, hormonal and environmental influences.

Classification
The classification of uterine fibroids is determined by their location (submucosal, intramural, subserous fibroids) and their manifestation usually depends on their location. right|300px |thumb| Uterus myomatosus – uložení 1) subserózní, intraligamentární; 2) intramurální; 3) submukózní; 4) subserózní pendulující; 5) submukózní pendulující intrakavitální; 6) cervikální intramurální; 7) cervikální stopkatý − myoma nascens

Clinical picture
The clinical picture may be completely asymptomatic (about 1/3 of women) or with typical symptoms such as menstrual cycle disorders: hypermenorrhea – excessive menstrual bleeding, menorrhagia – prolonged menstrual bleeding, dysmenorrhea – painful menstrual bleeding. In fertile women we may encounter infertility.
 * is determined by the size, location and number of fibroids;
 * the most common symptoms - irregular uterine bleeding, pain and pressure in the lower abdomen;
 * the arched fibroid compresses the endometrium – this disrupts vascularization and the wall does not separate;
 * large subserous fibroids can be asymptomatic and bother with pressure or pain from necrotic changes within the fibroid;
 * at fertile age, fibroids can cause infertility or sterility;
 * in těhotenství, fibroids usually grow faster.

Diagnostics

Therapy
Treatment of uterine fibroids depends on the symptoms. We choose a conservative solution for asymptomatic fibroids (1/3 of women need only monitoring) and for women of fertile age. If symptoms occur, surgical removal of the fibroid (hysteroscopic myomectomy, laparoscopic myomectomy, laparotomy myomectomy, laparoscopic uterine artery occlusion, fibroid embolization) or hysterektomie is necessary. In some cases, medication treatment may be indicated.
 * In young women who are planning a pregnancy:
 * conservatively - removal of fibroids and leaving the uterus;
 * laparoscopic or hysteroscopic enucleation;
 * GnRH agonists can be used to reduce large fibroids (treatment lasts 3-5 months).
 * However, fibroids most often occur in women who no longer plan parenthood:
 * if major bleeding, pain or rapid growth occurs - hysterectomy.
