urinary incontinence
three types of incontinence
- stress
- urge
- functional
when physical movement or activity occurs
stress incontinence
What causes the pelvic floor muscle and urinary sphincter to weaken ?
Stress incontinence
Ex:
Childbirth in women
Prostate surgery in men
Vaginal sling procedure helps..
Helps lift up the urethra
Overactive bladder **
Bladder spasms
Irritable bladder
Detrusor instability
Urge Incontinence
Involuntary urination with little or no warning
- frequent urination or Nocturia
Urge incontinence
Enuresis
Bed wetting
Enuresis happens with - incontinence
Urge incontinence
Inability to get to or use the toilet in time to urinate
Functional incontinence
Usually due to physical or cognitive impairment ?
Give some examples
Functional incontinence
- inability to walk well
- furniture in way
What treatment of incontinence aims at manipulating environment
Functional incontinence
- easy access to toilet
- scheduled times for toileting
- wearing clothes easy to remove
Anticholinergics treat
Urinary incontinence
What Anticholinergics treat urinary incontinence?
Oxybutyin (ditropan)
- Decreases urgency, frequency and Nocturia in overactive bladder
- causes urinary retention
Oxybutyin (ditropan)
Side effects of Oxybutyin
Hypertension
If a patient has BPH what can we not give?
Anticholinergics- Oxybutyin
What do we not give with decongestants?
- Claritin, Benadryl, Sudafed
Treatments for incontinence including medications
- Kegel exercises: helps strengthen muscles
- scheduled toileting times
- Botox injections
- nerve stimulator
Meds
- tolterodine (Detrol)
- Oxybutyin (Ditropan)
Inability to empty bladder all the way
Urinary retention
BPH is the #1 cause of
Urinary retention
If a patient is experiencing urinary retention and they have a obstruction what may they have?
A kidney stone
What medications can cause urinary retention?
Anticholinergics, opioids
Tumors, being dehydrated, and constipation can be signs of what?
Urinary retention
Sudden and often painful inability to urinate at all despite bladder fullness
Acute urinary retention
Gradual inability to empty the bladder; PainLESS retention associated with increased volume of residual urine
Chronic urinary retention
What is considered painful and an emergency?
Acute urinary retention
Straining to pass urine or a weaker flow of urine?
Chronic Urinary retention
Feeling like bladder is still full after passing urine
Chronic urinary retention
Overflow incontinence
Chronic urinary retention
Difficulty holding in urine while coughing/laughing
Chronic urinary retention
What are some things we can do for acute urinary retention? (7)
- bladder scan
- palpate height
- ask about voiding history
- needs indwelling catheter
- drink small amounts of fluids
- avoid alcohol, caffeine, acidic fruits
- sitting in tub of warm water or warm shower
What are some things we can do to help with chronic urinary retention?
- intermittent or indwelling catheter
- schedule toileting times
If a patient has a weak stream - what comes to mind first?
Prostate
Smoking is the most important risk factor with
Bladder cancer
PainLESS Hematuria can indicate what
Bladder cancer
Bladder irritability - Dysuria, frequency, and urgency can indicate what
Bladder cancer
Neurogenic bladder
Nerves between spinal cord and brain don’t work
> Parkinson’s, MS, stroke, diabetes
What can we do as a nurse for a patient with neurogenic bladder? (5)
- routine voiding measures
- avoid caffeine and alcohol
- kegel exercises
- catheter care when needed
- medication: tamsulosin
The med: tamsulosin (flomax) improves bladder storage and emptying for what condition?
Neurogenic bladder
Creatinine clearance (2)
- collect 24hour urine specimen
- closely approximates GFR
Serum creatinine (women)
What is the lab range?
1.2mg/dL and anything greater is abnormal
Serum creatinine for men
Normal lab value
1.4mg/dL and anything greater is abnormal
A patient has a high BUN with normal creatinine, what does this indicate?
Dehydration
7-20mg/dL
BUN normal ranges
What do we do with the first urine -creatinine clearance
Discard
Painful bladder syndrome
Interstitial cystitis
- difficult to diagnose
- mistaken for UTI but urine culture shows no bacteria
Interstitial cystitis
If a patient is experiencing
- pain in perineum
- persistent urgent need to void
