What is the rarest type of kidney stone?
cystine (building blocks of proteins)
What part of the kidney is retroperitoneal?
What are the three vessels of the kidney and what is their orientation within the hilum of the spleen?
- Anterior: Renal vein
- Middle: Renal artery
- Posterior: ureter
What is the fascia that covers both the kidney and suprarenal gland?
What is the deepest covering of the kidney?
true renal capsule
What lies between the true renal capsule and the renal fascia?
What are the four muscles that make up the posterior boarder of the kidney?
- Quadratus lumborum

What two vessels and bone have a posterior relation to the kidney?
- Subcostal vein and artery
- 12 rib
- left rib may go as high as 11 rib

What are the five branches of the renal artery?
- upper pole
- lower pole
- posterior part
- upper anterior
- lower anterior
What is different about the left renal vein?
longer and receives adrenal and left gonadal veins before passing anterior to AA and emptying into inferior vena cava
Right or left adrenal gland: tetrahedral, small, drains into IVC, lies posterior to IVC, superior part of kidney
Left or right adrenal gland: crescentic, big, drains into left renal vein, lies behind stomach, medial part of kidney
what is the length of the ureter and type of tissue lines it?
- transitional epithelium
What part of the peritoneum does the ureter descend in?
what muscle does the ureter lay on?
What two different structures does the ureter pass under in male vs female
- male: ductus deferens
- female: uterine artery
where in relation to the spine does the ureter descend?
near TP's of lumbar vertebrae

What are the three areas of risk for a stone in the ureter to be lodged?
- pelvi-ureteric junction
- Crossing the pelvic brim
- Intramural part where it enters the bladder
how do you find the superior and medial edge of the kidney?
- medial border is 5 cm from midline
- Superior border: T12 (R) T11 (L)
from superficial to deep, what are the layers of tissue that must be punctured for a renal biopsy?
- subcutaneous tissue
- quadratus lumborum
- pararenal fat
- renal fascia
- Perirenal fat
- renal capsule

what is the most inferior portion of the bladder?
what is the smooth muscle of the urinary bladder collectively called?
What type of tissue lines the inner wall of the urinary bladder?
what three openings make up the apexes of the urinary trigone?
- superior: two ureteric orifices
- inferior: Internal urethral opening
what is the blood supply of the bladder including parent and grandparent arteries?
Superior vesical artery <-- umbilical artery <-- ant div. internal iliac
Inferior vescial artery <-- ant. div. internal iliac a. <-- common iliac artery
what covers the superior surface of the urinary bladder?

- obturator internus
- levator ani
what is the space between the bladder and pubic bone?
retropubic (contains adipose tissue and veins)

- contraction of internal urethral sphincter during ejaculation
what are the three levator ani muscles
- pubococcygeus m.
- iliococcygeus m.
- puborectalis m.
