Pelvic Content- Urinary

Question 1

Urinary organs

Answer 1

Ureters

Urinary bladder

Urethra

Question 2

Ureters

Answer 2

25-30 cm long (begins at the renal pelvis and ends at the posterior aspect of the bladder)

Retroperitoneal

Abdominal and pelvic parts

Pelvic parts: begins at common iliac bifurcation and end at the posterior superior angle (bladder)

Question 3

Relations of the Ureters

Answer 3

Males (Anterior): Vas deferens

Females (Anterior): Uterine Artery

Question 4

Arteries of the Ureters

Answer 4

Males: Inferior vesical artery

Female: uterine artery

Question 5

Lymphatic drainage of the ureters

Answer 5

Lateral aortic, common iliac, external iliac, internal iliac

Question 6

Innervation of the Ureters

Answer 6

Renal, aortic, superior and inferior hypogastric plexus

Afferent (pain) fibers: T11-L2, retrograde fibers; Ureteric pain: groin

Question 7

Bladder

Answer 7

Composed of the detrusor muscle

Detrusor fibers: forms the internal sphincter (main sphincter of urinary control)

Surrounded by the vesical fascia (protects from mechanical damage or infection)

Question 8

Parts of the bladder

Answer 8

Apex

Fundus

Body

Trigone

Neck

Question 9

Surfaces of the Bladder

Answer 9

Superior: in close contact with the abdominal contents

Inferolateral

Posterior: in close contact with the rectum in male and in close contact with uterus in females

Question 10

Bladder pouches

Answer 10

Rectovesical (males): area between the posterior surface of the bladder and the anterior surface of the bladder

Vesicouterine pouch (female): area between the anterior surface of the uterus and the posterior surface of the bladder

Rectouterine pouch (females): are between the posterior surface of the uterus and the anterior surface of the rectum

Question 11

Retropubic space

Answer 11

Female: pubovesical ligament (keeps the urinary bladder in anatomical position)

Male: puboprostatic ligaments (keeps the urinary bladder in anatomical position)

Question 12

Trigone of the bladder

Answer 12

Delineated by both opening of the ureter and the outlet of the urethra.

Tissue in the trigone is different than the rest of the bladder

Question 13

Arterial supply of the bladder

Answer 13

Superior vesical artery

Inferior vesical artery (male)

Vaginal artery (female)

Obturator artery

Question 14

Veins of the Bladder

Answer 14

Vesical venous plexus

Prostatic venous plexus

Question 15

Lymphatics of the bladder

Answer 15

External iliac lymph nodes (superior)

Internal iliac lymph nodes (fundus)

Question 16

Innervation of the bladder

Answer 16

Vesical nerve plexus

Parasympathetic: Pelvic splanchnic nerves; Motor detrusor; relaxes the internal sphincter

Sympathetic (T11-L2)

Question 17

Male Urethra Parts

Answer 17

Pre-prostatic (bladder neck)

Prostatic

Membranous

Spongy

Question 18

Prostatic urethra

Answer 18

Widest and dilatable

Presents a urethral crest

Prostatic sinus (open up into the prostatic ducts; runs parallel through the urethral crest)

Seminal colliculus (verumontanum)

Prostatic utricle (atrophic in males and have no function; in females are the uterovaginal canal uterus and part of the vagina)

Question 19

Ejaculatory ducts

Answer 19

Drains in the prostatic urethra and are located at the anterior utricle

Question 20

Arterial supply of Male Urethra

Answer 20

Inferior Vesical Artery

Middle rectal artery

Question 21

Venous supply of male urethra

Answer 21

Inferior vesical vein

Middle rectal vein

Question 22

Lymphatic drainage of Male Urethra

Answer 22

Internal iliac lymph nodes

Question 23

Nerves of the Male Urethra

Answer 23

Pudendal and prostatic plexus

Question 24

Female Urethra

Answer 24

NO INTERNAL SPHINCTER (too short)

Paraurethral glands (prostate equivalent); lubricates distal porition of urethra

Question 25

Arterial Supply of Female Urethra

Answer 25

Internal pudendal and vaginal artery

Question 26

Veins of the Female Urethra

Answer 26

Internal Pudendal and vaginal veins

Question 27

Lymphatic drainage of the Female Urethra

Answer 27

Internal iliac lymph nodes
