Objectives
Objectives

  • Recognize age related lower urinary tract changes

  • Appreciate unique aspects of geriatric voiding problems

  • Distinguish among various forms of incontinence

  • Appreciate how non-urinary issues contribute to continence


Key points
Key Points

  • LUTS are common among the elderly

  • Patients frequently don’t mention it & physicians often don’t ask

  • Both patient and doctor frequently consider it a part of “normal aging”

  • LUTS are morbid, costly and lead to poor QOL

  • Majority of patients can be helped


Case presentation
Case Presentation

  • 84 yo male with spinal stenosis/immobility, mild dementia and parkinsonism develops fecal impaction and acute urinary retention. Prior to this he had frequent urgency, nocturia and occasional incontinence

    • Urinary catheterization 1.5 liters urine

    • Moderate size prostate

    • No hematuria, urine culture negative

    • PSA 4.2


Acute management
Acute Management

  • What is the appropriate immediate management?

    • Refer for TURP

    • Intermittent clean intermittent catheterization

    • Begin alpha blocker

    • Place Foley and begin alpha blocker, treat fecal impaction


Long term management
Long Term Management

  • Failed 3 voiding trials (persistent retention) over 4 weeks

  • How do you manage at this point?

    • Proceed with surgical options immediately

    • Continue more voiding trials

    • Clean intermittent catheterization

    • Chronic indwelling Foley

Lower Urinary Tract Symptoms


Changing paradigm of luts
Changing Paradigm of LUTS

  • Historically men with LUTS were considered to have “prostatism”

    • Elderly patients show higher rates of persistent symptoms/dissatisfaction after TURP

  • Women frequently assumed to have stress or urge incontinence

    • Surgical procedures, pessaries, Kegel’s exercise



The unreliable witness
The Unreliable Witness

  • Many asymptomatic elderly have UD evidence for detrussor overactivity

  • UD evidence of bladder outlet obstruction can be completely asymptomatic

  • Elderly woman frequently have high scores on IPSS and AUA symptoms scales

  • Among elderly men with BPH, many have residual symptoms after TURP


Ics definitions
ICS Definitions

  • Urgency

    • “Sudden compelling desire to pass urine which is difficult to defer”

    • Differs from the “normal desire to void”

    • Pathological

  • Frequency

    • The complaint that an individual urinates too much, typical ~8x/day

  • Nocturia

    • The complaint of awakening to void >1 time/night

  • Urge Incontinence

    • involuntary leakage accompanied by or immediately preceded by urgency


Lut changes in aging

Increased

Detrussor over activity

Nocturnal urine output

BPH

Post void residual <100cc~90%

Bacteruria~20%

Decreased

Bladder contractility

Bladder sensation

Sphincter strength

LUT Changes in Aging


Luts and aging
LUTS and Aging

  • Almost always multifactorial

  • Age associated LUT changes and comorbid disease associated

  • Major impact of conditions beyond the urinary tract in LUTS

  • Mobility, dexterity & cognitive influence on continence


Aging and continence
Aging and Continence

  • Most elderly people remain continent in spite of age associated LUT changes

  • Multiple factors interact to determine continence status

  • Intervention on all the contributing factors frequently yields good results

  • Looking for the one cause is wrong paradigm


Cerebral control of micturition
Cerebral Control of Micturition

  • Increasing research reveals that much of geriatric voiding dysfunction is “beyond the bladder”

  • Cortical & sub-cortical control over bladder function

  • Mostly inhibitory control that requires intact attention, working memory, executive functions


Incontinence
Incontinence

  • Common, morbid & costly

  • 25% of community dwelling elders are incontinent

  • 50% of nursing home residents

  • Leads to isolation, embarrassment, depression

  • Associated with falls, fractures, skin problems and institutionalization


Why is incontinence important
Why is Incontinence Important?

  • Social Stigma – leads to restricted activities

  • Depression

  • Medical complications – skin breakdown and

  • Increase in urinary tract infections

  • Institutionalization – UI is the second leading cause of nursing home placement


Types incontinence
Types Incontinence

  • Transient vs. chronic

  • Stress

  • Urge

  • Overflow

  • Functional


Transient incontinence
Transient Incontinence

  • Delirium

  • -Infection

  • -Atropine vaginitis or urethritis

  • -Pharmaceuticals

  • -Psychological disorders

  • -Endocrine Disorders

  • -Restricted mobility

  • -Stool impaction


Stress urinary incontinence
Stress Urinary Incontinence

  • Involuntary leakage on effort or exertion, or on sneezing or coughing

  • The sign of stress incontinence is the observation of urine loss from the urethra during coughing or straining

  • Cough stress test may be useful

  • Tends to be small amounts of leakage


Overflow incontinence
Overflow Incontinence

  • Leakage of urine associated with urinary retention

  • May be due to bladder outlet obstruction or poor bladder contractility

    • BPH with BOO

    • Urethral stricture, tumor

    • Diabetic cystopathy, multiple sclerosis, cauda equina etc.

  • Urodynamic studies to evaluate pressure/flow


Overactive bladder
Overactive Bladder

  • Urgency, with or without urge incontinence, usually with frequency and nocturia . . . if there …is no proven infection or other etiology

  • Equally common among men and women in the very elderly

  • 2/3 of OAB patients are “dry”

  • Dry patients still suffer


Oab symptom definitions
OAB Symptom Definitions

  • Urgency: a sudden compelling desire to pass urine that is difficult to defer

  • Urgency Urinary Inc. (UUI): involuntary leakage accompanied by or immediately preceded by urgency

  • Frequency: 8 voids / day = “normal”

  • Nocturia: patient wakes one or more times at night to void (sleep “before” and “after”)

Abrams P, et al. Urology. 2003;61:37-49.


Prevalence of oab age and gender
Prevalence of OAB Age and Gender

  • Prevalence of OAB

  • Men: 16.0%

  • Women: 16.9%

Nocturia
Nocturia

  • Definition

    • Waking up to void one or more times during the night

    • Voiding during intended sleep time that is preceded and followed by sleep

  • Associated with mortality

  • Disruptive to sleep, contributes to fatigue

  • Increased risk for falls 10% vs. 21% with 2 or more voids

Pharmacological treatment of nocturnal polyuria
Pharmacological treatment of nocturnal polyuria

Diuretics

  • Helpful in patients with lower limb venous insufficiency or congestive cardiac failure

  • Level 1 evidence, Grade C recommendation

    • Bumetanide 1 mg p.o. in afternoon

    • Furosemide 40 mg p.o. in afternoon

      Antidiuretics

  • Helps retain water until a more appropriate time

  • Reduce nocturnal voids and voided volume

  • Level 1 evidence, Grade A recommendation

Summary
Summary

  • Incontinence is not a “normal” part of aging

  • LUTS and OAB are very common

  • Most LUTS in the elderly are multifactorial

  • Don’t assume BPH is the etiology among elderly men

  • Use frequency-volume charts to diagnose nocturnal polyruria

  • Multiple treatment options exist for most
