Pelvis Flashcards
Lymph drainage ovaries
uterine fundus
body of uterus
Cervix
Ovaries = Para aortic
Uterine fundus = Also mainly para aortic
Body uterus = Along lymphatics in broad ligament to iliac lymph nodes
Cervix = to 3 potential = External iliac, presacral nodes, internal iliac nodes.
As you put catheter in prostatic urethra what happens?
And where does the resistance increase?
Resistance will actually decrease as the prostatic urethra is much wider
The most resistance is felt in the membranous urethra = As this is where the external sphincter normwally is.
Parts of male urethra
Spongy/Penile
Bulbar
Membranous
Prostatic
Pre prostatic
Muscles that attach to greater trochanter of femur
POGO
Piriformis
Obturator internus
Gemelli
Obtruator externus
MEANS = Quadratus femoris does not (instead intertrochanternic crest)
Female urethra lymph drains into?
Internal iliac lymph nodes
Lymph drainage of vagina
Superior vagina = Internal iliac (Same as urethra)
Inferior vagina = Superficial inguinal nodes
Denonvilliers’ fascia
Rectoprostatic fascia
Lowest part of the rectovesical pouch
Seperates prostate from bladder
Lymphatic drainage of the prostate
internal iliac nodes.
What are the contents of the superficial perineal pouch in men/women
Bulb of penis, crura of penis, superficial transverse perineal muscle, posterior scrotal arteries + nerves
In females = instead there are posterior labial artery+nerve
Note that the pudendal is in the deep perineal pouch and gives of branches to the superficial pouch
Blood supply to prostate
Done by inferior vesiclal artery which branches off the prostatovesical artery which comes from internal pudendal
Pelvic fracture with distruption at the border of membranous and bulbar urethra. Where will urine go?
Anteriorly into scrotal tissues
Because this area is in the superficial perineal puch
Lymph drainage of the male urethra by section
Outer part = Spongy urethra + Glans penis = Deep inguinal nodes
Inner part = Membranous + Prostatic urethra = Internal iliac nodes
Remember female urethra = Internal iliac (as all of it is ‘deep)
What structure provides the main support for the uterus
Central perineal tendon (also known as the perineal body
Longest part of male urethra
Spongy urethra = In the penis
What is bucks fascia
Deep layer of fascia that is continuous with external spermatic fascia and penile suspensory ligament
The membranous part of urethra is sorrounded by the Bucks fascia
What passess through greater sciatic foramen
Remember can be divided into supra and infa piriformis comaprtments
Supra piriformis = Superiof gluteal artery + vein, Superior gluteal nerve
Infra piriformis = Sciatic nerve, pudendal nerve, inferior gluteal artery and vein AND nerve, nerve to obtruator internus, nerve to quadratus femorus, posterior femoral cutaneous nerve
How does obtruator nerve leave the pelvis?
Leaves via the obtruator foramen in the obturator canal
Where is base and apex of prostate
Apex = Inferior part
Base = Superior part
THIS IS SAME AS PATELLA
Borders of urogenital triangle
Pubic symphysis at front
Line drawn between ischial tuberosities
Borders of posterior anal triangle
Caccyx at back
Line between ischial tuberosities
During DRE what is posterolateral to prostate
Seminal vesicles
THESE ARE ACTUALLY POSTERIOR AND LATERAL TO PROSTATE
And drain into prostatic urethra
What is palpated anterior to the vagina
The BASE of the bladder
Remember that the apex of the bladder is not flet = as this actually extends further superoanteriorly to the umbilius
