Internal Pelvic Organs Flashcards
What is found in the retroperitoneum?
Kidneys
Ureters
Suprarenal/adrenal glands
Great vessels of the abdomen & pelvis
What is found in the deep pelvic space?
Bladder
Rectum
Reproductive viscera.
Note:
It is continuous with the retroperitoneum.
What organs is the L kidney surrounded by?
Spleen
Pancreas
What ribs are posterior to the kidneys?
T11 and T12
Which kidney sits higher in the body?
Left kidney
Why is one kidney higher than the other?
The liver on the right pushes the kidney down a little because it is so big.
Which fat layer directly sits around the kidney?
Perinephric fat
Which fat layer is more superficial to the kidney?
Paranephric fat
What separates the perinephric and paranephric fat?
Renal fascia
What is the outermost layer of the actual kidney called?
Capsule
Describe the path of urine from the renal medulla to the bladder.
Renal pyramid => renal papilla => minor calyx => major calyx => renal pelvis => Ureter => bladder
How much of our kidney function can we lose prior to being symptomatic?
85%!
What can perinephric abscesses come from?
UTIs
Nephric abscesses
What supplies blood to the ureters?
Superiorly: renal artery
Abdominal: Gonadal, abdominal aorta, and common iliac
Pelvic: Internal iliac
What should we never do to a ureter’s blood supply?
NEVER reflect it away from the ureter!
Ideally, you want to push the ureter medially towards the blood supply.
What do ureters pass posterior to and anterior to?
Posterior to gonadal arteries
Anterior to the iliacs
How does the ureter get closed when the bladder is full?
The end of the ureter is like a flap, so it gets squished shut when the inside is full.
What is the proximal ureter made of?
Muscularis externa.
What is the distal ureter made of?
Thickened muscularis externa
What 3 locations do renal calculi typically lodge?
Renal pelvis
Crossing the pelvic brim/common iliac vessels
Entering the bladder wall
What kind of scan should we order for kidney stones?
KUB without contrast, aka a CT of the kidney, ureters, and bladder without contrast.
What other test can we do to look for kidney stones?
Cystoscopy
What muscle controls our bladder?
Detrusor muscle
What ligaments attach our bladder to the pubis?
Depending on the sex:
Puboprostatic/pubovesical ligaments
What is the trigone of the bladder?
It is the smooth part of the detrusor muscle, making a triangle between the two ureteric orifices and the urethra.
What is the line between the two ureteric orifices called?
Interureteric crest
What are some big differences between the urethra in a male and female?
Males have longer urethras that must pass through a prostate and are surrounded by the corpus spongiosum at the distal end.
