Q

UTI Etiology and Pathophysiology

A

Urinary tract above urethra normally sterile
 Defense mechanisms help prevent UTIs
 Complete emptying with void
 Ureterovesical junction competence
 Ureteral peristalsis propels urine towards bladder
 Acidic pH of urine (6.0-7.5))
 Abundant antimicrobial proteins and peptides
interfere with bacterial growth

Organisms from perineum ascend urethra
 GI tract: gram-negative bacilli
 Contributing factors: urologic instrumentation and
sexual intercourse
 Hematogenous transmission
 UTIs - most common health-care associated infection
(HAI)
 Catheter-associated urinary tract infections (CAUTIs)
—E.coli or Pseudomonas
 Increased length of stay, costs, mortality

Q

Obstructive Uropathies

A

Urinary obstruction—anatomic or functional
condition that blocks or impedes the flow of urine
 Congenital or acquired
 Damage occurs above level of obstruction
* Severity depends on location, duration, amount of
pressure or dilation, presence of urinary stasis or
infection
* May affect only one kidney and the other kidney may
compensate

Bladder neck or prostate
 Detrusor muscle hypertrophy
 Eventual large, residual urine
Bladder outlet
 Increased pressure with filling or storage
 Vesicoureteral reflux, hydroureter, and
hydronephrosis
 Chronic pyelonephritis and renal atrophy

Partial obstruction of ureter or ureteropelvic junction
(UPJ)
 Low to moderate pressure—kidney dilates without
noticeable loss of functions
 Urinary stasis and reflux—increases risk of pyelonephritis
 Both kidneys or only 1 functioning kidney involved—
changes in renal function occur and BUN and creatinine
increase
 Progressive obstruction can lead to renal failure
 Treatment—find and relieve blockage
 Insertion of tube, surgery, or urinary diversion

 Opioid analgesics and stool softeners; coping; and
follow-up care (regular cystoscopies)

42
Q

Intravesical Therapy

A

Local instillation of immunotherapy or chemotherapy
by urethral catheter
 Retained for 2 hours; change position every 15
minutes
 Weekly intervals for 6 to 12 weeks
 Induction and maintenance therapy
 Post procedure: irritative voiding and hemorrhagic
cystitis—increased fluids

43
Q

Urinary Incontinence

A

Involuntary leakage of urine
 More prevalent with older adults (women more than
men) but not a natural consequence of aging
 Gender differences
* Men—common with BPH or prostate cancer; overflow
incontinence from urinary retention
* Women—stress and urge incontinence

44
Q

UI Etiology and Pathophysiology

A

Bladder pressure greater than urethral closure
pressure
 Interference with bladder or sphincter control

DRIP
 D: delirium, dehydration, depression
 R: restricted mobility, rectal impaction
 I: infection, inflammation, impaction
 P: polyuria, polypharmacy

45
Q

Types of Urinary Incontinence

A

 Stress
 Urge
**Combined stress + urge = mixed incontinence
 Overflow
 Reflex
 Incontinence after trauma or surgery
 Functional incontinence
 May have more than 1 type

46
Q

UI Interprofessional Care

A

Many can be cured or improved
 Treat transient, reversible factors first
 Interventions depend on type
 Individualized to patient preference, type and severity,
and anatomic defects
* Lifestyle modifications
* Scheduled voiding regimens
* Pelvic floor muscle rehabilitation
* Antiincontinence devices
* Containment devices
Drug therapy
 Surgical therapy
-Depends of type of UI
* Urinary structural support/repositioning
* Increased urethral resistance of internal sphincter and
intraabdominal pressure reception
* Retropubic colposuspension and pubovaginal sling
* Suburethral sling
* Bulking agent injection
* Artificial sphincter surgery

47
Q

Urinary Retention

A

Inability to empty bladder with voiding or the accumulation of urine because of inability to void
 May be associated with leakage or post void dribbling—overflow UI
 Acute urinary retention—inability to pass urine; medical emergency
 Chronic urinary retention—incomplete emptying despite urination
 Post void residual (PVR)—normal 50 to 75 mL
* More than 100 mL—repeat or further evaluation with UTIs
* More than 200 mL—further evaluation

48
Q

UR Etiology and Pathophysiology

A

Bladder outlet obstruction—bladder can’t empty
due to severe blockage
 Men—enlarged prostate
 Deficient detrusor contraction—muscle can’t
contract with enough force or time to empty
bladder
 Neurologic diseases involving sacral 2, 3, and 4;
diabetes; overdistention; chronic alcohol use; and
anticholinergic drugs

49
Q

Diagnoses/Care for UR

A

Diagnostic studies (Same as UI)
 Urinalysis, post void residual, urodynamic studies,
ultrasound
 Interprofessional care
 Behavioral therapies (as with UI)
 Scheduled toileting and double voiding
 Catheterization: intermittent or indwelling
 Drug therapy

50
Q

UR Surgical Therapy

A

Surgical therapy—obstruction
 Transurethral or open techniques for:
* Prostate enlargement or cancer
* Bladder neck contracture
* Urethral strictures
* Dyssynergia of bladder neck
 Abdominal or transvaginal approach for:
* Pelvic organ prolapse
 Surgical therapy—deficient detrusor contraction
* Sacral neuromodulation
* Intraurethral valve pump

51
Q

Acute Urinary Retention

A

Acute urinary retention—emergency
 Insert catheter —consider indwelling
 Patient teaching to minimize risk:
* Drink small amounts throughout the day
* Be warm when trying to void
* Avoid excess alcohol
 Patient teaching if unable to void:
* Drink caffeinated coffee or tea to increase urgency
* Warm bath/shower
* Seek medical care

52
Q

Chronic Urinary Retention

A

Chronic urinary retention
 Behavioral methods
* Scheduled toileting; every 3 to 4 hours
 Catheterization
 Surgery
 Drugs

53
Q

Indwelling Catheter Indications

A

Indications for indwelling
 Relief of urinary retention
 Bladder decompression preop or postop
 Facilitate surgery
 Facilitate healing
 Accurate I & O—critical care
 Stage III or IV pressure ulcer
 Terminal illness—comfort

54
Q

Intermittent Catheter Indications

A

Indications for intermittent
 Relief of urinary retention
 Diagnostic study
 Urodynamic testing
 Sterile specimen
 Medication instillation
 Measure PVR

55
Q

Unacceptable Catheter Reasons

A

Unacceptable reasons for catheterization
 Routine urine specimen
 Convenience for nurse or patient’s family
 Complications of long-term use (more than 30 days)
 CAUTI—most common HAI
 Other: bladder spasms, periurethral abscess, chronic
pyelonephritis, urosepsis, urethral trauma or erosion,
fistula or stricture formation, and stones
