Urination and Faecal Elimination Terminology Flashcards
(22 cards)
Formation of urine
- Blood, waste & water enter the kidney via the renal artery
- Filtration & reabsorption
- Blood without waste or excess water leaves the kidney via the renal vein
- Excess water and waste, in the form of urine, leaves the kidney via the ureter
What is urination?
- Process of emptying the urinary bladder
- Also referred to as micturition or voiding
Signs of a healthy bladder?
- Empties 4-8 times each day (every 3-4 hours)
can hold up to 400-600 mL of urine (the sensation of needing to empty occurs at 200-300 mL) - May wake you up once at night to pass urine and twice if you are older (i.e. over 65 years of age)
- Tells you when it is full but gives you enough time to find a toilet, empties completely each time you pass urine, and does not leak urine.
Urine Characteristics
- Volume: 1500 mL/day;
- 0.5 - 1mL per kg per hour
- Colour: straw, amber
- Clarity: transparent
- Odour: faint
- Sterility: urine in the bladder is sterile
pH: 4.5-8
Urination is impacted
- Developmental stage
- Fluid & food intake
- Muscle tone
- Positioning
- Psychosocial factors
- Medications
- Pathologic conditions, pregnancy, surgical & diagnostic procedures
Diuresis
increased or excessive production of urine.
Polyuria
Passing abnormally large amounts of urine
Oliguria
low urine output
Anuria
Lack of urine production.
Nocturia
Urinating frequently at night.
Haematuria
- Blood in Urine
Enuresis
Night time loss of bladder control, or bed-wetting, usually in children.
Incontinence
the loss of bladder contro
Retention
A condition in which you are unable to empty all the urine from your bladder
Neurogenic bladder
- People who lack bladder control due to a brain, spinal cord or nerve problem
Urine Clinical Reasoning Cy
- Review current information
Patient history
Current health problem
Subjective data - Gather new information
Urinalysis
Specimen collection, MSU - Recall knowledge
Risk factors
Pathophysiology
Urinary diversions, incontinence, catheter care
Urinalysis
Leukocytes – white cells in the urine (pyuria) which is associated with urinary tract infection.
Cloudy urine – infection
Midstream urine specimen
Urine culture to identify micro-organisms causing urinary tract infection (UTI)
- Clean catch specimen of urine collected in sterile jar
Midstream urine specimen
- Cleaning urinary meatus
- Mid stream catch after initial flow
- Not contaminating jar/lid
Urinary incontinence
- Loss of bladder control
- Stress incontinence - leakage of small amounts of urine during activities that increase pressure inside the abdomen and push down on the bladder, such as coughing, sneezing, laughing, walking, lifting, or playing sport.
Urinary incontinence who is at risk
- Women in late pregnancy, or with weakened pelvic floor muscles; men who have prostate disease; people with chronic diseases such as diabetes, emphysema; obesity; constipation
Management of urinary incontinence
- Fluid intake (1.5-2 litres)
- Prevent constipation
- Correct positioning on toilet
- Pelvic floor exercises
- Keep a bladder diary (3 days at least)
- Bladder training – learning to ‘hold on’
- Introduce incontinence aides/products
