Ureters
Ducts allowing urine to pass from the kidney to the bladder
Bladder
- sterile urine storage
- can store up to 600ml
- feel urge at 200 ml
- under voluntary control until greater than 700ml
Urethra
- channels urine to outside of body from bladder
- 1-2in F 8in M
Color of urine
-pale to dark yellow
Transparency of urine
Clear
-if cloudy suspect infection
Odor of urine
- aromatic
- vitamins, antibiotics can cause strong, sharp odor
Volume of urine
1200-1500 ml/day
Specific gravity of urine
- measures urine density/concentration
- normal 1.003-1.030
- dilute if
pH of urine
5-7 is normal
Urine is acidic
Cells/cast/crystals in urine
- Detected on microscope exam
- RBC’s (2-3) & WBC’s (4-5) are normal
- casts are rare
- hyaline may be found after strenuous exercise or diet therapy. Others may indicate a pathological dysfunction
- crystals found normally. If increase, can cause renal stones (uric acid)
Electrolytes in urine
No glucose, ketones, or protein
Kidneys
- 2 bean shaped structures
- contain about 1million nephrons
- nephrons are functional units
- urine drains into the kidney pelvis
- less than 30ml per HR may be due to kidney failure
- hypertension may lead to renal insufficiency
Micturation
another name for urination
Urgency
sudden need to urinate
may be related to fluid intake, inflammation, or infection. may cause incontinence
Nocturia
excessive voiding at night
may be related to heart failure, diuretics, CHF, or elderly

Clinical problems with renal-urinary system
may be associated with:

- prolonged catherization
- medications
- pathological problem
Residual Urine
urine left in the bladder after voiding
- increased risk for UTI
- Check MD prameters
Urinary Tract Infections
Lower:
-Cystitis
*culture to confirm
*have increased WBC & RBC’s, and bacteria with dysuria frequency, urgency, cloudy urine, voiding multiple small amounts.
Upper(these people are really sick and dehydrated):
-Pyleonephritis (infection of kidney which is more serious)
*lethargy, fever, chills, HA, vomiting, abdominal pain
TO PREVENT: increase fluids, shower not bath, wipe front to back, wash hands, increase acid in urine
Renal Stones
same a kidney stones
S/S depending on locale:
-can cause colicky pain in lower back and abdomen that radiates to lower legs
Spasms can cause dysuria, urgency, and frequency
backing up of urine can be serious (hydronephrosis)
