Bladder Tac related Surgeries:
pubovaginal Sling, TVT (tension
vaginal tape, A & P Repair, etc.)
Can be both or one or the other
Fertility Specialists
Oncology Gynecologist
Pubovaginal sling and TVT are bladder suspension procedures for incontinence when bladder descends into vagina. Pubovaginal sling can be done thru abdomen or vagina. TVT done laparoscopically usually in conjunction with A & P Repair. TVT stands for tension free vaginal tape also use cystoscope to place for r/o of inadvertant urethral or bladder puncture.

7. Anatomy & Physiology External Female Genitalia (Vulva) Mons pubis
Labia majora
Labia minora
Urethral orifice
Vaginal orifice
Clitoris
Hymen
Perineum
Anus

8. External genitalia
Labia minora form the clitoris and contain sebaceous glands
Vestibule is the cavity between the labia minora
Contains urethral meatus and Bartholin’s (vestibular) glands
Perineum is the area between vaginal opening and anus
Can stretch with delivery however is frequently cut with an incision called episiotomy to prevent spontaneous tears during vaginal delivery

10. Internal Structures Vagina External Cervical Os Cervix Uterus
Layers of:
peritoneum
myometrium
endometrium
Parts of:
Body
Fundus
Adnexa
Fallopian Tubes
Ovaries
Supporting Structures

11. Vagina Receptacle to penis Passageway for menstrual flow
Lower portion is the birth canal

13. Uterus Function: Site of menstruation Or
Site of implantation if implantation occurs then is the site of fetal development

14. Uterus Parts of: Dome shaped portion=fundus Central portion=body
Where narrows=cervix
Internal cervical os=where uterus and cervix meet
External os=where cervix meets vagina

15. Uterus
Lining of:
Perimetrium=outside of uterus covered in a this serous membrane lining
Myometrium=
-smooth muscle lining
-middle layer
-fetal support
-during labor expels
fetus with assistance of
hormone oxytocin
3. Endometrium=inner lining 2 parts:
stratum basalis permanent layer thin
Stratum functionalis
-produced by s. basalis
-temporary layer
-shed w/menstruation
-produces maternal portion of placenta

16. Uterus
Blood supply:
Uterine artery and uterine vein

17. Fallopian tubes are open to the abdomen=problem with venereal disease/can wreak havoc

18. Ovaries Function: Production and expulsion of oocytes (ova or eggs)
Release of hormones: estrogen and progesterone
Are both endocrine and exocrine glands
Exocrine produce eggs (ducts=fallopian tubes)
Endocrine portion produces estrogen and progesterone

19. Ovaries Attachments: Broad ligament
-largest formed by a fold of peritoneum
-contains fallopian tube, round and ovarian ligaments, blood vessels, lymphatics, and nerves
Suspensory ligament
Ovarian ligament

20. Ovaries Suspensory ligament -small peritoneum fold
-holds ovaries at upper end
-contains blood vessels and nerves
Ovarian ligament
-attaches ovaries at their lower end
-is actually a thickening in the broad ligament

22. Fallopian tubes
Egg is caught by finger-like projections called the fimbrae after it is released from the ovary
Funnel shaped end prior to fimbrae=infundibulum

23. Fallopian tubes 2 layers: 1.Mucous membrane innermost
Is lined with ciliated columnar epithelial tissue
Allows for movement of the egg
Scarring from STDs can damage or scar this lining rendering a female sterile

24. Fallopian tubes 2. Muscularis Smooth muscle
Peristalsis or movement of the egg
So…
Egg movement through the fallopian tubes occurs by cilia and peristalsis
Fertilization must occur in the distal 1/3 of the fallopian tubes for successful implantation into the uterus

25. Physiology
Ovarian cycle caused by anterior pituitary gland which secretes:
LH “ovulation hormone”
FSH levels must be low to allow ovulation
Causes secretion of estrogen
Menses is caused by a sudden decrease in estrogen and progesterone triggered by no fertilization
Luteinizing hormone and follicle stimulating hormone. Corpus luteum produces some estrogens, but primarily progesterone

26. Hormones 1. FSH Produced in anterior lobe pituitary
Causes graafian follicular development
Causes estrogen secretion

27. Hormones LH Produced in anterior lobe pituitary
Continues follicular development
Stimulates estrogen and progesterone production
Causes ovulation

28. Hormones
Estrogen
Maintenance and development of reproductive organs and female sex characteristics

29. Hormones Progesterone Primary cause of endometrial changes
With Prolactin (hormone) influences mammary glands to develop and secrete milk
Milk secretion and labor is stimulated by oxytocin (hormone)

30. Physiology
In the ovary > the big 4 hormones are increasing which develops a follicle
Follicle becomes a graafian follicle
Graafian follicle rupture>egg released into fallopian tubes
Outer rind of graafian follicle becomes corpus luteum

31. Physiology 2 possibilities:
No fertilization=corpus luteum degenerates and becomes corpus albicans and cycle starts over
Fertilization=corpus luteum maintained four months to suppress egg production and menstruation with estrogen and progesterone
Progesterone levels must be high enough to maintain endometrial lining to sustain pregnancy
Corpus luteum acts as a temporary endocrine gland
After four months placenta is developed and takes over

32. Obstetrics

33. Pregnancy (Obstetrics) Procedures
Cerlage (MacDonald or Shirodkar)
Deliveries:
Vaginal
Cesarian sections (C-sections)
Tubal ligations (sterilization procedures)
Emergent hysterectomy
Cerclage-suture removed prior to delivery.

34. Pregnancy Terminology
Labor
Four stages of:
True labor onset
Cervical dilation complete>birth
Birth>placental delivery
Placental delivery > stabilization of mother
Primapara
6-18 hours
½ - 3 hours (dilation 1 cm/hr)
0-30 min
6 hours
Multipara
2-10 hours
5-30 min (dilation 1.2cm/hr)
0-30 min
6 hours
True labor is NOT Braxton Hicks contractions. Varies depending on whether mother primapara or multipara.

35. Pregnancy Terminology
Braxton Hicks - “false labor”
Bloody show – onset of labor
Cervical dilation - cervical measurement (0 to 8cm)
Cervical Effacement – thinning of cervix
Crowning - neonate head circumference at its largest point as it passes thru vulvar ring

36. Pregnancy Terminology
Descent – movement of fetus thru pelvis with contractions
Expulsion – delivery of infant
Gravida - how many times a woman has been pregnant
Parity – number of time a woman has given birth
Position – relationship between presenting infant part & pelvis of mother
(OA) most common
Presentation – fetal part overlying pelvic inlet
Station – measurement of the descent of the infant’s presenting part thru the ischial spines
Parity twins indicate monparity. Nulliparus = no births. OA occiput anterior. Presentation should be head, may be breech (buttocks) or compound (more than one part)

37. Presentation Breech - buttocks first Transverse – crosswise
Footling – feet
Vertex – upper back of head

38. Obstetrical Complications
Placenta previa – placental implantation over cervix
Abruptio Placenta – premature placental separation

39. Obstetrical Complications
Abortions
Missed
Incomplete
Imminent
Spontaneous
Voluntary
Missed-conception parts of non-living and in uterus more than 2 months. Incomplete-products of conception retained in uterus. Imminent-about to abort. Spontaneous-abortion occurs without being induced.
