KIDNEY AND URETERS

1. ANATOMY

The  two kidneys are situated on either side of the midline,  the

hilium  being  at the level of the lower border of  first  lumbar

vertebra. 

They  weigh about 160 gms each and are surrounded by  perinephric

fat. The right kidney is 1-2 cm. lower than the left.

The kidneys are protected posteriorly by the 11 + 12th ribs,  the

quadratus lumborum and the psoas major muscle.

The anterior relations are colon, duodenum and suprarenals at the

upper poles. The pancreas is one additional anterior relation  of

the left kidney 

The  kidney  is a solid organ made up of an outer cortex  and  an

inner placed medulla.

The cortex contains the glomeruli (Shown below) and a port of the tubucles. The

medulla  contains  the rest of the tubule and  collecting  ducts.

The collecting ducts open into the minor calices and these  minor

calyx open into the major calyx which open into the renal pelvis.

1.1 Ureters

The  calyceal system of the kidney opens into the  funnel  shaped

renal pelvis that narrows into a muscular tube 28-30 cm long  and

5 mm in diameter.

This tube courses through the retroperitoneum just lateral to the

transverse  processes  of the lumbar vertebra, crosses  into  the

bony pelvis at the bifurcation of the iliac vessels and then ends

at the trigone of the bladder.
