retroperitoneal
The kidneys are organs, located behind the
peritoneal cavity

retro= backward, back, behind,
peritoneal= pertaining to
peritoneum
Where are the kidneys located
They are present on
either side of the spine in
the lumbar region at the
level of the 11th and 12th
ribs
Each kidney consists of …parts
cortex
medulla
cortex
outer part of the kidney
(cortex means bark of a tree)
medulla
inner part of the kidney (medulla: means marrow, innermost part)
Hilum
depression on the medial border of the kidney through which the ureter, blood vessels and nerves pass
•renal artery enters the hilum
•renal vein leaves the hilum
•ureter leaves the hilum
Cali/o, calic/o
Calyx small cup
Caliectasis
Dilatation of calyx
Caliceal
Pertaining to calix
pyel/o
renal pelvis
Pyelolithotomy
Renal pelvis is surgically opened to remove the large stones
renal pelvis (pyel/o)
All collecting tubules/ducts lead to
Small cup like regions of the renal
pelvis called…..receive the urine and empty
it into the renal pelvis
calyces or calices
(singular = calyx or calix; cali/o or
calic/o
The renal pelvis empties urine into
the …
ureter
ureter/o
ureters
Ureteroplast
surgical repair of ureters
Ureters extend from
are narrow tubes (16-18 inches long) which
extend from renal pelvis to urinary bladder. They carry urine from a kidney to the urinary
bladder
cyst/o, vesic/o
urinary bladder. hollow muscular organ
that temporarily stores urine . It excretes urine through urethra
Cystoscopy
process of visualization of bladder
trigon/o
triangle (Latin)
A triangular region at the base of
the bladder where ureters enter, and urethra exits.
Urinary meatus
(meat/o) external
opening of the urethra.
urethr/o
urethra. Tube which carries urine from bladder to outside of body
Urethritis
Inflammation of urethra
Urethroplasty
Surgical repair of the urethra
Urethral stricture
Abnormal narrowing of the urethra
Urethrotomy
Incision of the urethra, for relief of a stricture.
Urethrotome
Surgical instrument for cutting a urethral stricture.
Nephron
Functional units of kidney which form urine
Each nephron contains:
• glomerulus (cluster of capillaries)
• bowman’s capsule (membrane surrounding the glomerulus)
• renal tubule (long twisted tube attached to bowman’s
capsule)
glomerul/o
Glomerulus
Glomerulus
A small convoluted or intertwined mass (of capillaries or nerve fibers). Glomus: ball
nephropathy
disease of kidney
nephrosis
abnormal condition of kidney
nephrectomy
removal of kidney
nephrogram
record of kidney
nephritis
inflammation of kidney
nephrolith
kidney stone
nephrologist
kidney specialist
nephrosclerosis
hardening of kidney arterioles
nephroptosis
abnormal drooping of kidney into pelvis (floating kidney)
nephropexy
fixation of kidney
-pexy
Fixation
