WE WILL TAKE ABOUT:

Kidney

Ureter

Urinary Bladder

Urethra

KIDNEY

Renal vein, renal artery and ureter are found in the sinus in anterior to posterior order

4

INTERNAL STRUCTURE OF THE KIDNEY

Each kidney consists of: Outer cortex convex Inner medulla concave

formed of renal pyramids with apex forming renal papilla it’s open to the

Minor calyces Major calyces Renal pelvis fills most of

the sinus Cortex extends into

medulla as renal columns

ANTERIOR RELATION Right kidney: Suprarenal gland Liver Duodenum Right colic flexure Ileum Left kidney: Suprarenal gland Stomach Spleen Splenic artery Pancreas Jejunum Left colic flexure

POSTERIOR RELATION OF THE KIDNEY

Diaphragm separates the kidney from the pleural cavity and 11th and 12th ribs

Psoas major medially

Quadratus lumborum in the middle

transversus abdominis laterally

NOTE

The right and lift kidney are similar except the right kidney does not have 11th rib

URETER

It shows three constriction along its course:

1.Between ureter and pelvis

2.At crossing the external iliac artery

3. At entrance to urinary bladder

BLOOD SUPPLY OF THE URETER

Uretric branches of common iliac

Uretric branches of internal iliac

gonadal arteries
