Mrs. R



85 y/o female brought to the emergency
room with new onset urinary incontinence.
Daughter is worried about possible UTI and
inability to care for patient at home if
incontinence persists.
PMH: Dementia, hypertension, advanced
osteoarthritis, gait disturbance.
Meds: ASA 81mg daily, hydrochlorothiazide
12.5 mg daily, calcium with vitamin D tid.
Mrs. R
 SH: lives with daughter and grandson.
Dependent on family for assistance with
ADL’s.
 Physical Exam: BP 138/80 P78 R18 T98 Gen:
Alert, cooperative, vague historian; Chest:
Clear; CV: RRR; Abdomen: Benign; GU:
Atrophic changes; Ext: Trace edema
Screening

Ask sensitively worded questions
Detailed History



Duration, previous
evaluation/treatment?
Volume, how often, what situations?
Urgency, dysuria, straining?
EVALUATION:
THE APPROACH
Focused H & P for:
1) Reversible conditions
2) Conditions that require Urologic
or Gynecologic consult or
Urodynamics early on.
3) Function focused approach to the
remaining cases
4) Contributing factors
Evaluation, continued



UA, C&S
Creatinine, BUN, Glucose, Calcium,
?PSA
Post-void residual
Clinical urinary stress test
Voiding record
Post-Void Residual (PVR)




Measure volume of urine left in bladder after
voiding by catheter or bladder scan
< 50-100 Normal
100—400 Monitor until consistently less than
200cc.
> 400cc—Insert Foley catheter
Clinical Stress Test

Bladder should be full. Ask patient to strain
(Valsalva maneuver). If no leakage, have her
perform a half sit-up and cough—look for
leakage. If no leakage in supine position,
repeat testing in standing position. Patient
should relax perineum and cough once—if
immediate leakage=stress UI; if leakage is
delayed several seconds=detrusor
overactivity
20 Common Problems in Urology; JM Teichman, Ed. 2001
2003 GAYFP; DB Reuben et al
Established Incontinence





URGE
STRESS
Mixed type (both urge and stress)
OVERFLOW (increased PVR)
“Functional” incontinence
Urge Incontinence




Most common
Detrusor overactivity with uninhibited bladder
contractions
Unpredictable, abrupt urgency, frequency,
variable volumes lost, PVR usually normal
(“Post-void residual”—the volume of urine left
in bladder after spontaneous voiding)
Management: bladder retraining, scheduled
toileting, pelvic muscle exercises (PME),
pharmacologic agents
Stress UI




2nd most common cause in aging females
Impaired urethral closure due to insufficient
pelvic support, sphincter opens during
bladder filling
Leakage occurs with  intra-abdominal
pressure
Management: pelvic muscle exercises,
biofeedback, electrical stimulation, adrenergic agonists, pessary, surgical
interventions.
Mixed Incontinence



Features of both urge and stress
incontinence.
Common in older women
Management: bladder retraining, pelvic
muscle exercises, other pelvic muscle
rehabilitative options outlined
previously, pharmacologic agents.
Overflow UI





Detrusor underactivity and/or outlet
obstruction
Continuous small volume leakage
Dribbling, weak stream, hesitancy, nocturia
Outlet obstruction=2nd most common cause
of UI in Males
Detrusor underactivity Urinary retention &
overflow Incontinence in 12%F; 29%M
Overflow UI

Management: Obstruction—Treat
cause; -antagonists. Detrusor
Underactivity—Review meds, double
voiding, intermittent selfcatheterization, Crede’s.
“Functional” Incontinence



Unable or unwilling to toilet due to
physical impairment, cognitive
dysfunction, environmental barriers
No underlying GU dysfunction

Pleasant, thin 86 y/o with c/o urgency,
frequency, with variable UI for past 2-3 years.

compression fractures, hypertension

mg weekly; amlodipine 5 mg daily; MVI daily

Gen: Thin, alert, excellent historian.
CV, Pulm, Abd, Neuro: all neg
GU: Ext genitalia/BSU/Vag– Atrophic;
no pelvic relaxation; Bimanual exam:
consistent with previous hysterecomy,
no masses. RV:Confirmatory
Mrs. J


PVR: 250 ml
Clinical stress test: Some urine loss
after several seconds delay after cough
DHIC
(Detrusor Hyperactivity with Impaired Contractility)
Most common cause of UI in frail
and old:
Detrusor hyperactivity plus impaired
bladder contractility (DHIC).
The clinical picture is:
a “story” of Urge incontinence with
elevated or borderline PVR
ie PVR= 100-400 cc range.
Management of UI



Treat reversible cause (ie. Constipation)
Review meds
General measures: Behavioral
interventions before pharmacologic Rx,.
Avoid caffeine & ETOH, minimize
evening intake, pads, Surgery last.
Pelvic Muscle exercises




Motivated patient, careful instruction
56-95% decrease in UI episodes—
dependent on intensity of program
Focus on pelvic muscles (10 ctx 3-10
times/d)—avoid buttock, abdomen,
thigh muscle contraction.
Biofeedback may help
Bladder Retraining



Urge control exercises
Scheduled toileting
Prompted toileting
Pelvic Muscle Rehabilitation



Detailed instruction of pelvic muscle
exercises
Biofeedback techniques
Electrical stimulation
Anticholinergic Drugs






Oxybutynin
Tolterodine
Trospium
Darifenacin
Variety of preparations: Immediate Release;
Extended Release; Transdermal
Outcomes same; Try different agent if one
doesn’t work
***** ALL these drugs suppress the detrusor contractility and MAY CAUSE
URINARY RETENTION!!! ALWAYS CHECK PVR PRIOR TO
PRESCRIBING!!!
Overflow UI


Obstruction—Treat cause;
-antagonists; finasteride
Detrusor Underactivity—Review meds,
double voiding, intermittent selfcatheterization, Crede’s.
Further Urological Evaluation




PVR > 400 cc
Poor response to treatment
Cystometry, cystoscopy, urodynamic
studies
Evidence of GU tract pathology
UI Summary





Look for reversible causes and Rx
Check PVR (>100 cc investigate further)
Start with behavioral interventions
before meds
Referral and urodynamic studies if no
response to usual measures
Early referral if underlying GU tract
pathology present
