Urinary Flashcards
ADH
More water reabsorbed in distal tubule, less urine
Aldosterone
Sodium and water reabsorbed in greater quantities, increase blood volume
Detrusor muscle
Allow bladder to expand and contract
Enuresis
Involuntary passing of urine
Diuretics
Increase urine formation by preventing reabsorption of water and electrolytes
Medications that cause urinary retention
Anticholinergic
Antihistamines
Polyuria
Abnormally large amounts of urine by the kidneys
Polydipsia
Excessive fluid intake
Oliguria
Low urine output
Impaired blood flow or renal failure
Anuria
Lack of urine production
Peritoneal dialysis
Solution instilled into abdominal cavity through catheter, rests, then removed through catheter
Neurogenic bladder
Impaired neurological function that interfere with urination
Urinary retention
Overdistension of bladder
Normal amount daily adult
1200-1500 mL
Blood urea nitrogen BUN
Urea, the end product of protein metabolism, is measured as BUN
Creatinine clearance
Breakdown of protein
Tests for function of kidneys
BUN 8-21 mgldl
(Cr) .61-1.21 mg/dl
Ratio 15:1
BUN 8-21 mgldl
(Cr) .61-1.21mg/dl
Ratio 15:1
Credes maneuver
Manual pressure on bladder to empty
Suprapubic catheter
Inserted surgically through abdominal wall above symphysis pubis into urinary bladder
Ureterostomy
One or both ureters brought to side of abdomen to form small stomas
Nephrostomy
Diverts urine from kidney via catheter inserted into the renal pelvis to a nephrostomy tube and bag
Vesicostomy
May be formed when bladder is left intact but voiding through the urethra is not possible
Ileal conduit
Most common incontinent urinary diversion.
Segment of ileum removed and intestinal ends are reattached. One stoma one pouch
Continent urinary diversion
Kock pouch, neobladder, internal pouch
Glomerulus
Tuft if capillaries surrounded by bowman a capsule
