Embryology of the Female Reproductive tract The Development of the gonadal system begins at the 5-6th week of gestation Female development is determined by the presence of XX At ~9th week of gestation the Mullerian and Wolffian ducts coexist The absence of testosterone leads to regression of the Wolffian duct The absence of Anti-Mullerian Hormone allows for the development of the Mullerian Ducts Mullerian Ducts (paramesonephric) The Mullerian Ducts develop Cephalocaudally from the embryonal mesoderm forming the f ll fallopian tubes b The Mullerian Ducts then fuse distally creating the uterus, cervix and upper 1/3 of the vagina. By the 12th week of gestation, the Uterus assumes its mature morphological shape. By the 22nd week of gestation, the entire process is complete resulting in uterus, cervix and uterine cavity. Mullerian Duct Anomalies are a result of interruptions at different stages of development of the female genitourinary system. Renal tract anomalies are associated with MDA in up to 30% of cases due to the close embryologic relationship between the paramesonephric and mesonephric ducts. Garel L et al.

Her pediatrician saw an abnormal vaginal opening and referred the patient to a gynecologist. HPI ◦ The patient reported thelarche at age 11 and adrenarche at age 12. ◦ She denied vaginal spotting, unusual drainage, and either cyclical or noncyclical abdominal pain. ◦ She was otherwise healthy and on no medications. ◦ She denied any sexual activity. FH- Her family history was negative for any gynecological issues. PE- ◦ Tanner stage 4 breasts and a normal abdominal examination without any discomfort or palpable masses. ◦ She refused a pelvic examination because the last time it was very uncomfortable. Imaging- An abdominal ultrasound examination performed in the office revealed a small uterus and normal ovaries. Lab Studies- ◦ Follicle-stimulating hormone and estradiol levels were in the normal postpubertal range. Plan◦ Her gynecologist suspected outflow obstruction, either imperforate hymen or transverse vaginal septum and took the patient to the operating room. ◦ After making the initial incision into the hymenal region, no fluid collection was identified, and indeed, no vaginal canal could be found. The surgery was terminated, and the patient was then referred to a tertiary care center.

Class III III-- Unicornuate Uterus Imaging ◦ Ultrasound Suggested if a small, rounded uterus is identified in the lateral aspect of the pelvis Cannot accurately detect this MDA type ◦ MRI MRI Criteria for classification Uterine body and fundus- Elongated, banana-shaped, eccentric uterus One O normal-sized l i d hhorn with i h normall endometrial—myometrial d i l i l width id h ratio i A rudimentary horn may be present, may have endometrial tissue, and may communicate with main canal Classified according to rudimentary horn as follows: absent rudimentary horn rudimentary horn present with no endometrial tissue (nonfunctioning) rudimentary horn present with endometrial tissue that communicates with main cavity rudimentary horn present with endometrial tissue that does not communicate with main cavity and may obstruct. The latter may present with abdominal pain and require surgical intervention Cervix- Normal If nonfunctional uterine horn is present, then it typically has a low signal intensity on T2weighted MRI with loss of normal zonal anatomy If functional uterine horn is present after puberty, it appears as a cavity deformed by the enlarged rudimentary horn which has high-signal-intensity center on both T1-T2 weighted images (finding compatible with hematometra) 6 1/27/2011 Class III III-- Unicornuate Uterus Class III III-- Unicornuate Uterus Class II: Unicornuate Uterus Management ◦ Nonfunctional rudimentary horn No surgical intervention required ◦ Functional noncommunicating horn Resection of rudimentaryy horn byy laparoscopy p py or laparotomy p y Pregnancy can occur regardless of if horn is communicating or noncommunicating If pregnancy is identified before mid-second trimester then abortion is recommended If pregnancy achieves mid-second trimester, then attempt tocolysis Do not use oxytocin, prostaglandin, or uterine stimulants Hysterotomy should be completed if uterine wall thickness is <5mm or fetal lung maturity obtained. Class III III-- Uterine Didelphys A 23yo G2P3, with a documented 2-horned, bicervical uterus, was diagnosed at 9 weeks with a twin pregnancy, with one embryo in each hemiuterus. HPI- PE- ◦ Abdomen was soft non-tender to palpation, no rebound/gaurding ◦ Mild irregular uterine contractions with no changes of the 2 cervices at digital examination. ◦ Fetal tracing and ultrasonography were normal for both fetuses. Day #1 ◦ Labs- Hemaglobin- 10.4 g/dL; platelet count and liver enzymes were normal. No proteinuria was detected. ◦ Diagnosis of PTL was considered and Tocolytic given (nicardipine 2mg/h). Betamethasone was also administered for fetal lung maturitation. ◦ Uterine contractions ceased rapidly, but the patient still complained of abdominal pain, which intensified the following day. Day #2 ◦ At 27 weeks, the patient presented with sudden abdominal pain developed in the right groin radiating to the lumbar region. Patient reported no vaginal bleeding, no loss of fluid, irregular contractions, fetal movement present. ◦ LabsHemoglobin -8.5 g/dL. Platelet count, prothrombin time, and activated clotting time were normal. Liver function tests showed no hepatic cytolysis, but total hyperbilirubinemia, mostly the free form, and hemolysis were present. The urinary dipstick became protein positive. ◦ Despite tocolysis, irregular uterine contractions reappeared and vaginal bleeding occurred. ◦ Abruptio placentae in the right horn was suspected, and an elective cesarean was determined to be necessary. The twins were delivered through transverse hysterotomies, performed on both hemiuteri, but the incision in the right horn proved to be transplacental. The placentas were removed, and no evidence of abruptio placentae was found. Externalization of the uterus didelphys revealed a 180° clockwise torsion of the right hemiuterus. Upon retrospective review of all ultrasound reports, the placenta in the right horn was found to be inserted in the posterior wall on the last examination, performed 48 hours before the delivery, thereby confirming that the posterior wall of the right horn, erroneously thought to be the anterior wall, was incised during the cesarean. Both neonates had uneventful postnatal outcome and were discharged at 6 and 8 weeks. 7 1/27/2011 Class III: Uterine Didelphys Class III III-- Uterine Didelphys Class III: Uterine Didelphys Uterine didelphys is a symmetric anomaly Two completely separate uterine cavities are identified each with normal zonal anatomy, endometrial cavity and cervix Occurs at the 9th week of gestation when both paramesonephric ducts develop but the ducts fail to fuse at resulting in a duplicated system. system The presence or absence of vaginal septum is defined by the degree of fusion failure No communication between the two cavities is present Complete or partial longitudinal vaginal septum is associated with the anomaly in 75% of cases Some patients with uterine didelphys present with unilateral hemivaginal septum hematometrocolpos Class III III-- Uterine Didelphys Symptoms ◦ Symptoms are related to presence of obstruction ◦ Nonobstructive uterus didelphys Asymptomatic Diagnosed incidentally during pelvic exam when two cervices are identified Diagnosed incidentally during imaging for another indication ◦ Obstructive uterus didelphys Obstructed hemivagina typically becomes symptomatic with menarchecyclic pelvic pain Endometriosis Pelvic adhesive disease 8 1/27/2011 Class III III-- Uterine Didelphys Class III III-- Uterine Didelphys Obstetric Complications ◦ Fetal survival occurs in 41-64% of pregnancies ◦ Premature births occur 20-45% of the time ◦ Miscarriages g occur in 32-52% of women Class III III-- Uterine Didelphys Class III III-- Uterine Didelphys Imaging ◦ Ultrasound Two completely separate uterine horns, each with its own endometrial cavity can be visualized No communication between the two horns can be seen Large fundal cleft may be noted, as well as, cervical duplication ◦ MRI MRI Criteria for Classification Uterine body and fundus- Two separate uteri, which can be joined at body; deep fundal cleft Endometrium- No communication between the two endometrial cavities, normal endometrial—myometrial width ratio in each uterus Cervix- Double Vagina- Longitudinal or oblique vaginal septum always present Hematometrocolpos with varying degrees of distention may also be visualized within an obstructed hemivagina 9 1/27/2011 Class III- Uterine Didelphys Class III- Uterine Didelphys Dykes, T.

Typically this resorption should occur by the 12th week of gestation. Studies have linked presence of a uterine septum with genetic absence of bcl-2 gene which is responsible for apoptosis. Septum is located in the midline fundal region Septum is composed of poorly vascularized fibromuscular tissue Complete septum extends from the fundal zone to the internal or external os and divides the endometrial cavity A partial septum does not reach the internal os 13 1/27/2011 Class V- Septate Uterus Class VV- Septate Uterus Symptoms ◦ Typically Asymptomatic ◦ Complete Septum unilateral obstruction dysmenorrhea endometriosis Dykes, T.
