6.3 Urinary Elimination Flashcards
Urination
- Also called voiding or micturition
- Consists of Kidneys, Ureters, Bladder, and Urethra
- Most people void 3-4 times a day
- More frequent urine can mean infection or laxity in pelvic muscle
- Retention can be due to blockage from prostate enlargement for men or pelvic musculature prolapse for women, bladder cancer, and medication.
Urinary Incontinence Types
Overflow - Overdistension and overflow of bladder
Functional - Factors outside of urinary tract
Reflex - Emptying bladder without sensation of need to void
Total - Continuous, unpredictable loss of urine
Stress - Involuntary loss of urine related to increased pressure in abdomen from sneezing, laughing or coughing
Urinary Incontinence Types
Transient - Appears suddenly and lasts 6 months or less
Mixed - Urine loss from 2 or more types of incontinence
Factors affecting Micturition (urination)
Children - (2-5) Toilet Training and Enuresis (involuntary)
Elderly - Decreased muscle tone and strength, nocturia (wake up at night with need to urinate), medications increasing urine production
Food/Fluid Intake - Dehydration/food causing urine production
Factors Affecting Micturition (cont)
Psychological - Stress from not having privacy (bedpan) or voiding in unfamiliar place
Pathological - Acute Kidney Injury (AKI), UTI, Urinary Calculi (stones), Chronic Kidney Disease (CKD), Hypertension, Diabetes mellitus.
- Medications
- Congenital urinary tract abnormalities (present at birth)
Caring for patients with UTI
- Sexually active women more at risk for UTI
(Bacteria likely to flow from vagina to urethra) - Urinating after sex helps flush bacteria
- Spermicidal jelly can change protective bacterial flora in vagina.
- Post Menopausal women have urinary stasis, decreased vaginal flora, and pelvic floor musculature laxity.
Caring for Patients with UTI
- People with catheters are at risk of bacteria entering up tube.
- CAUTI is most common Hospital Acquired Infection
- Diabetes Mellitus more at risk
- Men with enlarged prostates are at risk
Medication affect on Urine
Anticoagulants - Hematuria (blood in urine) resulting in pink/red color
Diuretics - Prevents reabsorption of water and certain electrolytes causing lighter urine color
Cholinergic Medication - Stimulates contractions of detrusor muscle, producing urination
Medication affect on Urine
Analgesics/Tranquilizers - Suppress CNS, diminished neural reflex
Phenazopyridine (pyridium) - OTC pain reliever that causes orange or red color of urine
B-Complex Vitamins - Changes urine to blue/green
Levodopa (L-Dopa) - Changes urine brown or black
Kidney Assessment of Urinary Function
- Palpation of kidneys preformed by advanced health care practitioner as part of a more detailed assessment
Urinary Bladderm
- Palpate and Percuss or use bedside scanner
Urethral Orifice
- Inspect signs of infection, discharge or color
Skin
- Inspect color, texture, turgor and excretion of wastes
Urine
Assess color, odor, clarity, sediment (matter that settles at the bottom)
Measuring Urine Output
- Void into bedpan, urinal, or specimen container
- Urometers attached to catheters are the most accurate way to assess urine output
- Wear gloves and pour urine into measuring device such as calibrated container to measure urine output.
- Read at eye level on a flat surface
Normal Urine
- Pale yellow, straw, or amber in color
- Clear and translucent without exudate, pus, or sediment
- Free of malodorous odor
- Ammonia odor means bacterial action
- Minimum of 30mL an hour
Urinalysis
- Collected in Cup and Measured with Dipstick
- Measures Infection/Dehydration
- Menstrual flow can alter results as blood is a component
- Process/refrigerate specimen within an hour of collection
Urine Cultures
- Collected in sterile container to grow bacteria and determine pathogen
- If there is pain when urinating (sensitivity) antibiotics are placed in petri dish to determine which ones kill the pathogen
24 hour urine
- Used to diagnose kidney disease by evaluating creatine and protein
