Urinary Elimination
-Urine collects in bladder until sensory nerve endings called strech receptors are stimulated by pressure. ---> transmits impulse to spinal cord causing internal sphincter to relax ---> stimulates urge to void.
-Urinary tract eliminates solute waste from blood, serving to control blood concentration & removes excess fluid/electrolytes.
-Reabsorbs nutrients to maintain optimal ion concentration needed for neuronal/muscle function

Urine Production & Urine Elimination see flashcards
Dx tests
Urinalysis: Supports Dx & evaluates bladder emptying & renal function
Ultrasonic Bladder Scan : Examines residual urine
Uroflowmetry: Measures volume of urine voided/sec
Cystometrograohy: Evaluates bladder capacity
Radiologic
1) Intravenous pyelography (IVP) 2) Renal arteriography
Cystoscopy: Direct visualzation of bladder wall & urethra (can be used for biopsy or stone removal)
CT scan/MRI
Renal ultrasound

Concepts related to...
Fluid&Electrolytes:
Blood tests
Urea/Creatine levels : Evaluates renal function
Decreased renal function = ^^ med toxicity, ^^ electrolytes/water, ^^BP
^^urination = decreased electrolytes/water & BP
Decreased water consumption causes constipation
Diarrhea causes decrease water and electrolytes
