Urology And Nephrology Flashcards
Upper Urinary Tract
Kidneys- nephrology
Production
Lower Urinary Tract
Bladder/urethra- urology
Storage
Functions of Kidney
Excrete waste Retrieve filtered particles Maintain acid/base balance Regulate BP Stimulate erythrocyte production
Definition of azotemia
Abnormal increase in the concentration of non-protein nitrogenous wastes (urea and creatinine) in blood
Pre-renal causes
Dehydration Hypoadrenocorticism Cardiac disease Shock Hypovolemia
Renal causes
(Parenchymal disease) Parenchymal disease Infections Cysts Inflammation Neoplasia Toxins
Post-renal causes
Obstructive
Blockage - urethral/bladder or urethral
T/F
Azotemia is not uremia
TRUE
Definition of Renal Failure
The clinical syndrome that occurs when kidneys are no longer able to maintain:
Regulatory function
Excretory function
Endocrine function
75 % of nephron population is non-functional
Renal Disease Definition
The presence of morphological or functional lesions in one or both kidneys, regardless of extent
Uremia definition
The constellation of clinical signs and biochemical abnormalities associated with critical loss of functional nephrons
The glomerular filtration rate is directly related to _____________
Renal functional mass
Gold Standard test for measuring glomerular function
Clearance of radioisotopes with renal scintigraphy
Urea is synthesized in the ______ and excreted by the _________
Liver; kidneys
Serum Urea levels are affected by
Species/age Liver function Dietary protein content Endogenous protein catabolism Renal function
