GU (Exam 3) Flashcards
(141 cards)
Urinary incontinence
loss of urinary control
Enuresis
involuntary urination by a child after 4-5 years of age
causes may be psychological and structural, but usually resolves with or without treatment
Nocturnal Enuresis
bed wetting
Stress Incontinence
loss of urine from pressure exerted on the bladder by coughing, sneezing, laughing, exercising or lifting something heavy
occurs when sphincter muscle of the bladder is weakened
pregnancy, childbirth, menopause, cystocele, prostate removal, obesity, chronic coughing are contributing factors
Overactive bladder (Urge Incontinence)
sudden, intense urge to urinate followed by an involuntary loss of urine
CAUSES: UTIs, bladder irritants, bowel conditions, smoking, Parkinson’s disease, Alzheimer’s disease, stroke, injury, nervous system damage
Reflex Incontinence
urinary incontinence caused by trauma or damage to nervous system; urgency is generally absent
detrusor hyperreflexia
Detrusor hyperreflexia
increased detrusor muscle contractility that occurs even though there is no sensation to void
Mixed Incontinence
occurs when symptoms of more than one type of urinary incontinence is experienced
Overflow Incontinence
inability to empty the bladder or retention; dribbling urine and a weak urine stream
CAUSES: bladder damage, urethral blockage, nerve damage, prostate conditions
chronic overdistention occurs because of a perceived inability to interrupt work to void that results in detrusor muscle areflexia and overflow incontinence
Functional Incontinence
occurs in many older adults who have a physical or mental impairment that prevents toileting in time
Transient Incontinence
urinary incontinence resulting from a temporary condition
CAUSES: delirium, infection, atrophic vaginitis, certain meds (diuretics, sedatives), psychological factors, high urine output, restricted mobility, fecal impaction, alcohol, caffeine
Gross Total Incontinence
a continuous leaking of urine, day and night, or the periodic uncontrollable leaking of large volumes of urine; the bladder has no storage capacity!!
CAUSES: anatomic defects, spinal cord/urinary system injury, fistulas between bladder and adjacent structure like vagina
Risk Factors for Incontinence
female
advancing age
overweight
smoking
renal disease
Complications for Incontinence
skin breakdown
recurrent UTIs
negative psychological consequences
interruption of usual activities
Neurogenic Bladder
bladder dysfunction caused by an interruption of normal bladder nerve innervation
MANIFESTATIONS ARE SYMPTOMS OF AN OVERACTIVE/UNDERACTIVE BLADDER
Neurogenic Bladder Causes
brain/spinal cord injury
nervous system tumors
brain/spinal cord infections
dementia
Parkinson’s
spina bifida
diabetes mellitus
stroke
meds
vaginal childbirth
MS
chronic alcoholism
lupus
heavy metal poisoning
herpes zoster
Interstitial Cystitis/Bladder Pain Syndrome
chronic bladder condition more common in women and aging people that causes pain and pressure in suprapubic, pelvic, and abdominal area
EXACT CAUSE UNKNOWN!!
5% experience symptoms for 2+ yrs and below 5% develop end stage disease where bladder hardens, capacity is low and pain worsens
Interstitial Cystitis/Bladder Pain Syndrome Manifestations
pain in urinary tract (often worse with pressure)
frequency and nocturia
urgency (often constant worsened by stress)
sexual dysfunction
Urinary Tract Infection (UTIs)
among the most common bacterial infections encountered in clinical practice, most commonly an ascending infection
Risk Factors for UTIs
female genitalia
sexually active (multiple partners increases risk)
use of diaphragm with spermicide
history of diabetes
recent instrumentation (catheters)
structural abnormalities
improper personal hygiene
immobility
Upper UTIS
pyelonephritis (acute and chronic)
Lower UTIs
cystitis and urethritis
Cystitis
infections in the bladder where the bladder and urethra walls become red and swollen; bacteria ascend to the bladder via urethra and possibly further up to kidneys (E. Coli 75-95%)
CAUSES: infection and irritants
Lower UTI Symptoms
burning on urination
urgency
dysuria
frequency
low back pain
foul smelling urine
cloudy urine (pyuria)
hematuria
fever (occasionally)
