1. CONGENITAL MALFORMATIONS OF THE ♀ GENITAL TRACT

2. OBJECTIVES You should understand the clinical presentations, complications and management of the following malformations: 1-Mullerian agenesis 2-Disorders of lateral fusion of the mull ducts A-uterus didelphus B-bicornuate uterus C-septate uterus D-unicornuate uterus E-unicurnuate with rudimentary horn 3-Disorders of vertical fusion of the mullerian duct A- vaginal septum B-cx AGENISIS / DYSGENISIS 4-Unusual configuration of vertical/lateral fusion defects 5-Defects of the external genitalia A-Ambiguous genitalia B-Defects of the clitoris B-Defects of the clitoris C-Imperforate hymen C-Imperforate hymen

3. 1-MULLERIAN AGENISIS Mayer –Rokitansky-Kuster-Huser syndrome Etiology ? Failure of mullerian duct development  absence of the upper vagina, cx & uterus (uterine reminants may be found) The ovaries & fallopian tubes are present Normal 46XX ♀ with normal exrenal genitalia Pt present with 1ry amenorroea 47% have asociared urinary tract anomalies 12% skeletal anomalies Rx  psychological counseling  - vaginoplasty surgical  - vaginoplasty - excision of utrine reminant (if it has functioning endometrium) -vaginal dilators

12. 2-DISORDERS OF LATERAL FUSION OF THE MULL DUCTS Incidence ? 0.1-2% 4% of infertile pt 6-10% recurrent abortion pt Most pt can conceive without difficulty  Incidence of : ◊ recurrent abortions ◊ premature birth ◊ premature birth ◊ fetal loss ◊ fetal loss ◊ fetal malpresentation ◊ fetal malpresentation ◊ C S ◊ C S ◊ cx incompetence ◊ cx incompetence

13. 2-DISORDERS OF LATERAL FUSION OF THE M D CLINICAL PRESENTATION ♣  ♣Shortly after menarche  if there is obstruction to uterine blood flow ♣  longitudinal vaginal septum ♣Difficulty in intercorse  longitudinal vaginal septum ♣Dysmenorrhea or menorrhagia ♣Dysmenorrhea or menorrhagia ♣Abnormality detected on D&C ♣Abnormality detected on D&C ♣U/S, laparoscopy or laparotomy ♣U/S, laparoscopy or laparotomy ♣Palpable mass ♣Palpable mass ♣Complications of pregnancy ♣Complications of pregnancy ♣HSG  during infertility or RFL investigations ♣HSG  during infertility or RFL investigations

14. NON OBSTRUCTIVE MALFORMATIONS OF THE MULLERIANE DUCTS

15. 2-DISORDERS OF LATERAL FUSION OF THE MULL DUCTS A-Uterus didelphus Complete duplication of uterus, cx & vagina (due to failure of fusion of the two Mull ducts) ?  pregnancy wastage?  pregnancy wastage  HSG or at laparoscopy / laparotomyDx  HSG or at laparoscopy / laparotomy  If affecting pregnancy outcome  surgical correction (metroplasty)Rx  If affecting pregnancy outcome  surgical correction (metroplasty) B-Bicornuate uterus Incomplete fusion of the two Mull ducts  pregnancy wastage  pregnancy wastage  HSG or at laparoscopy / laparotomyDx  HSG or at laparoscopy / laparotomy  If affecting pregnancy outcome  surgical correction (metroplasty)Rx  If affecting pregnancy outcome  surgical correction (metroplasty)

16. 2-DISORDERS OF LATERAL FUSION OF THE MULL DUCTS C-Septate uterus External contour of the uterus is normal but there is intrauterine septum of varying length & thickness Worst pregnancy outcome  Dx  both HSG & laparoscopy  Hystroscopic excision of the septum Rx  Hystroscopic excision of the septum D-Unicornuate uterus Due to development of only one Mull duct Almost all pt have associated single kidney  similar to pt with didelphic uteri Pregnancy outcome  similar to pt with didelphic uteri Dx  HSG or surgery Dx  HSG or surgery  NO corrective surgery Rx  NO corrective surgery  if pt has associated cx incompetence  cx cerclage cerclage

17. 2-DISORDERS OF LATERAL FUSION OF THE MUL DUCTS E-Unicurnuate with rudimentary horn Noncommunicating horn 90% Present with cyclic pelvic pain, mass, ectopic pregnancy in the rud horn or endometriosis Rx  surgical excision Communicating horn Present with ectopic pregnancy in the rud horn or  pregnancy wastage

18. 3-DISORDERS OF VERTICALE FUSION OF THE MULLERIAN DUCTS A- VAGINAL SEPTUM Faults in the junction between the Mull. Tubercle & the urogenital sinus  could be very thick or thin 85% in upper two third of the vagina Pt present 1ry amenorrhea, hematocolpus, mass or cyclic abdominal pain  incidence of endometriosis Rx  surgical exision B-Cx AGENISIS / DYSGENISIS V rare Difficult, unsuccessful surgical correction Rx  hysterectomy
