Urinary Incontinence and
Pelvic Organ Prolapse
UNC School of Medicine
Obstetrics and Gynecology Clerkship
Case Based Seminar Series
Division of Urogynecology/
Reconstructive Pelvic Surgery
Objectives
 Describe normal pelvic anatomy and pelvic support
 Describe screening questions to elicit signs and
symptoms of urinary incontinence
 Differentiate the types of urinary incontinence
 Describe the anatomic changes associated with
urinary incontinence and pelvic organ prolapse
 Describe medical and surgical management options
for urinary incontinence and pelvic organ prolapse
Rationale
 Patients with conditions of pelvic relaxation and
urinary incontinence present in a variety of ways.
 The physician should be familiar with the types of
pelvic relaxation and incontinence and the approach
to management of these patients.
Definition of Urinary Incontinence
 International Continence Society
 Involuntary urine loss
 Severe enough to constitute a social or hygiene problem
 Leakage is objectively demonstrable
Questions for Patients
 Do you leak urine when you cough, sneeze, laugh, or
exercise?
 Do you leak on the way to the bathroom?
 Do you know the locations of bathrooms when you are
shopping or travelling?
 Do you leak during intercourse?
Stress or Urge Incontinence?
Epidemiology
 Estimates of prevalence vary
 Bias in sample surveys
 Patient under-reporting
 Differences in definitions, populations studied and
methods used
 ~ 13 million Americans are incontinent
 10-35% of adults
Economics in Urinary Incontinence
 Direct health care costs
 > $15 billion/yr
 Indirect health care costs
 Incontinence products
 Loss of work/productivity
Classifying Urinary Incontinence
 Stress
 Loss of bladder support -> leak with cough/sneeze/valsalva
 Urge
 Overactive bladder spasms -> leak with urge
 Mixed
 Both of above
 Overflow
 Hyposensitive bladder -> leak when reach capacity
 Other
 Functional – can’t make it to bathroom (physical or
cognitive impairment)
 Unconscious or Reflex – hyperreflexia of detrusor
 Fistula – tract between bladder and vagina

 Site-specific exam
 Assess each compartment – anterior, posterior, apical, uterine
 Use Q-tip and speculum to identify specific prolapse
 Site-specific approach to repair
 Anterior, posterior, apical, uterine
 Treatment focused on symptom improvement, not anatomical
correction
