Flashcards in L18: Basic Reproductive Sx (Case) Deck (19):
1

gonadectomy

surgical removal of the reproductive organs (ovaries, testes)
-OVH and castration most common method and procedure in US

2

indications for elective gonadectomy

-pet overpopulation (>3 million dogs and cats euthanized in shelters annually)
-sex-based aggression
-mammary neoplasia (90% malignant in cats!)
-pyometra
-uterine/ovarian neoplasia
-prostatic disease
-perineal herniation
-testicular neoplasia

3

what % of intact female dogs get pyometras by 10yrs of age?

25%

4

what % uterine/ovarian neoplasia benign?

90%

5

T/F: risk of ovarian tumor small

T
-epithelial (adenoma or adenocarcinoma) or stromal (granulosa cell)

6

incidence of prostatic disease in intact dogs

50% by 5yrs
-ie. cysts, abscess

7

consequences of perineal herniation

-dyschezia, obstipation, fecal impaction, bladder retroflexion, tenesmus, rectal prolapse, incontinence, infection
-high surgical failure w/o castration
-95% of those that get it are male and intact
-very common and extremely painful

8

prostatic neoplasia and elective castration

-study concluded that prostatic carcinoma/adenomacarcinoma 2.8x greater than intact, but was biased
-has low incidence to begin with

9

testicular neoplasia and elective castration

-sertoli cell, leydig and semimomas common, which is prevented and usually curative with castration since these tumors rarely spread

10

preparation for sx

-PE of CV, respiratory, hydration, body condition, and integument

11

pre-op diagnostics

PCV and TS
BG and BUN
Chemistry, CBC, and UA
ectoparasites, fecal exams and viral screens

12

complications of castration

-hemorrhage (hematoma 10%)
-urethral ligation
-prostatic ligation
-surgical site infection (rare)

13

how to tx hemorrhage in spayed female

-make incision bigger
-If R ovarian pedicle, use mesoduodenum to retract viscera
-soak up blood with lap pads, find pedicle and put ligature on it
(more common to have bleed/remnant on R side because it is tucked up higher in the abd)
-triple clamp with encircling ligature with transfixing ligature above it to minimize chance of bleed

14

more common for uterine a. to get ligated than ovarian a.

:)

15

incidence of surgical site infection

t need to put on prophylactic/therapeutic abx

16

complications of OVH

-hemorrhage
-ureteral ligation
-ovarian remnant
-urinary incontinence

17

what hormone causes pyometra?**

progesterone
-comes from ovaries only
-dilates uterine smooth m., while cervix closes up and glands produce secretions

18

what percent of ovarian remnants occur on R side?

70%

19

what % of neutered female dogs will develop urinary incontinence, esp. if neutered early?

12% (70% develop lower pressure, usually subclinical)
-recommend neutering large breed dogs at 8mo.
