11; 6
The average kidney weighs about __ grams.
145
Ren(o)
Kidney
Nephr(o)
Kidney
Nephrectomy
Surgical excision of a kidney
Nephromegaly
Enlargement of a kidney
Determine the efficiency with which the kidneys excrete a particular substance; Diagnostic evaluation of the kidneys
Renal Clearance Test
Accumulation of waste products in the blood owing to inadequate functioning of the urinary system
Uremia
The process of diffusing blood through a semipermeable membrane for the purpose of removing toxic materials and maintaining acid-base balance in cases of impaired kidney function
Kidney dialysis or Hemodialysis
Dialysis through the peritoneum, the dialyzing solution being introduced into and removed from the peritoneal cavity; Alternative to hemodialysis
Peritoneal Dialysis
Making a record of the urinary system
Urography
Ureter(o)
Ureter
Pertaining to a cyst or fluid-filled sac such as the bladder
Cystic
Urethr(o)
Urethra
inflammation of the kidney; also called Bright’s disease
Nephritis
Most usual form of nephritis
Glomerulonephritis
clusters of capillaries that act as filters
Glomeruli
Toxic or destructive to kidney cells
Neprhrotoxic
Destruction of the kidney
Nephrolysis
Freeing of a kidney from adhesions
Nephrolysis
Pertaining to the heart and kidneys
Cardionephric
Abnormal softening of the kidney
Nephromalacia
Enlargement of the kidney
Nephromegaly
Enlargement of one kidney
Unilateral nephromegaly
Enlargement of both kidneys
Bilateral nephromegaly
Ultrasonic scanning of the kidney
Nephrosonography
Tomography of the kidney
Nephrotomography
Film produced by nephrotomography
Nephrotomogram
Surgical fixation of the kidney
Nephropexy
A condition in which the kidney gradually ceases to remove metabolic wastes and excessive water from the blood. Uremia is a major characteristic. Kidney impairment is not reversible once the disease progresses to the end stage
Chronic Renal Failure (CRF)
Gradual downward displacement of the kidney. Also called floating, hypermobile, or wandering kidney. Can occur when the kidney supports are weakened by sudden strain or a blow, or it may be present at birth. Can be corrected by nephropexy
Nephroptosis
Sclerosis or hardening of the artery
Nephrosclerosis
Any disease of the kidney characterized by degenerative changes, especially the renal tubules, without the occurrence of inflammation
Nephrosis
A classification that includes all diseases of the kidney characterized by chronic loss of protein in the urine and subsequent depletion of body protein, especially albumin
Nephrotic syndrome
A renal disorder in which the kidneys are enlarged and contain many cysts. Also called polycystic renal disease
Polycystic Kidney Disease
Inflammation of the kidney and its renal pelvis, owing to infection
Pyelonephritis
Destruction of the kidney characterized by the production of pus with total or almost complete loss of renal function
Pyonephrosis
Severe narrowing of the renal artery, thus reducing blood flow to the kidney
Renal artery stenosis
Formation of urinary calculi
Urolithiasis
Pyel(o)
Renal pelvis
Py(o)
Pus
Pertaining to the blood vessels of the kidney
Renovascular
Another name for renal calculus or kidney stone
Nephrolith
Removal of a renal calculi by cutting through the body of the kidney
Nephrolithotomy
Dissolving a stone
Litholysis
Surgical crushing of a stone
lithotripsy
A stone is crushed with an instrument called a…
lithotrite
Newer method of breaking up stones; used on stones that resist passage and is far less incapacitating than a full-scale surgery
Extracorporeal shock wave lithotripsy (ESWL)
Requires the use of an instrument that is inserted into a small incision in the renal pelvis and allows the nephrologist to view inside the kidney
Nephroscopy
Creation of a new opening in the kidney
nephrostomy
The skin is punctured to gain access to the kidney and then a catheter is placed into the renal pelvis; allows for drainage, drug installation, and selected surgical procedures, including removal of calculi
Percutaneous Catheter Nephrostomy
Distention of the renal pelvis with urine as a result of an obstructed ureter
Hydronephrosis
Loss of kidney function
Renal Failure
Radiographic study of the blood vessels of the kidney
Renal angiography
A kidney’s functional units; its components are glomerulus and tubules
Nephrons
Glomerul(o)
Glomerulus
A type of inflammation of the kidney in which the glomeruli are involved
Glomerulonephritis
Serves as a filter for the blood; allows water, salts, wastes, and practically everything except blood cells and proteins to pass through its thin walls
Glomerulus
Collects the substances that filter through the glomecular walls and passes them to the long twisted tube, the tubule
Bowman’s Capsule
The part of the renal tubule that is near the glomerulus and Bowman’s capsule is the…
Proximal Tubule
The function of the nephron is…
filtering of the blood and reabsorption of substances that the body conserves
Filtering occurs in what part of the nephron?
Glomerulus
In what part of the nephron does reabsorption occur?
Tubule
Inflammation of the renal pelvis
Pyelitis
Formation of a new opening into the renal pelvis
Pyelostomy
Surgical procedure to remove a stone from the renal pelvis
Pyelithotomy
