Female Urogenital - Bauck Flashcards
Caslick’s indications
- pneumovagina
- age-related poor perineal conformation
- urine pooling
- perineal injuries
- racehorses
Perineal laceration classification
1st degree: vestibule and vulva (sx not ush required)
2nd degree: perineal body, vestibule, and anus
3rd degree: rectovaginal septum
Rectovaginal fistula
Perineal lacerations are most common in
first foal mare with unassisted deliveries
Perineal laceration surgeries
- Wait 30 days for feces to soften, edema to resolve
- two week diet of equine senior before and after
- Mineral oil and magnesium sulfate per NGT
- May have to stage repair, come back later to finish
Aanes technique
Two stage repair for perineal lacerations
- Sedated and restrained in stocks
- First stage -> rectovestibular shelf reconstructed w/out repair of perineal body
- Second stage 3-4 wks later to reconstruct perineal body
To repair a rectovaginal fistula, turn it into
3rd degree perineal laceration
Urethroplasty indication
Urine pooling (urovagina) from poor perineal conformation
Urovagina can lead to
- cervicitis
2. endometritis-decreased fertility
Along with urethroplasty
weight gain also recommended
Urethroplasty surgical techniques
- Monin Urethroplasty
- Caudal relocation of transverse fold - Brown, McKinnon, Shires technique
- Caudal urethral extension
Cervical lacerations
- caused by trauma or dystocia
- Palpation more helpful than speculum
- Surgical repair indicated
- High rate recurrence
- Perform sx during diestrus; at least 3 weeks post-partum
Cervical lacerations are repaired during
DIESTRUS; at least 3 weeks post-partum
Cervical laceration sx
- Standing with caudal epidural
- Finochietto/Aanes retractors
- Stay sutures on cervix, retract caudally
- Long-handled instruments
- 3 layer repair
Cesarean section
- Consider other approaches first (15-20 minutes)
- assisted delivery
- controlled vaginal delivery - Hemorrhage is very pronounced
- Horses in extension puts pressure on Femoral n.
Hemostasis
Whipstitch can help control bleeding
- simple continuous suture along entire edge of hysterotomy incision
- to close do simple continuous with an inverting oversew, do not include placenta
Give oxytocin IV
Only after hysterotomy incision is closed
Uterine torsion
- Last two months gestation (NOT AT TERM)
- Can be clockwise/counter-clockwise
- Dx via rectal exam
- 360 degrees
- Failure to tx can kill baby, cause chronic torsion
Uterine torsion tx
- Rolling
- Caudal ventral midline approach
- Flank approach
Uterine torsion-rolling
Roll in direction of torsion, wooden plank across mare’s flank
Uterine torsion-Caudal ventral midline approach
Use if
- large fetus
- nonviable fetus/uterus
- uterine rupture or concurrent GI lesion suspected
Uterine torsion-flank approach
Incision made on side toward which uterus is twisted
Uterine torsion prognosis: Mare survival
< 320 days = 97%
> 320 days = 65%
*Very good prognosis for rebreeding
Uterine torsion prognosis: Foal survival
< 320 days = 72%
> 320 days = 32%
Foal survival is significantly better if torsion corrected by
standing flank laparotomy than by midline celiotomy
