Causes of Acute & Reversible Forms of Urinary Incontinence D Delirium R Restricted mobility, Retention I Infection*, Inflammation*, Impaction (fecal) P Polyuria**, Pharmaceuticals * Urinary Tract Infection, Atrophic vaginitis, urethritis. ** Hyperglycemia, Congestive heart failure.
Persistent Incontinence 1. Stress Leakage of urine (small amounts) with increases in intraabdominal pressure 2. Urge Leakage of urine (larger volume) due to inability to delay voiding after sensation of fullness 3. Overflow Leakage of urine (small amounts) from urinary retention 4. Functional Leakage of urine (larger volume) with inability to toilet due to impaired cognition, physical function, psychological, environmental barriers
Causes of Persistent Incontinence 1. Stress Pelvic floor, Bladder outlet or Urethral sphincter weakness 2. Urge Overactive bladder, Detrusor hyperreflexia due to Cystitis, Urethritis, Tumor, Stone, Diverticuli,Stroke, Dementia, Parkinsonism, Suprasacral spinal cord injury 3. Overflow Obstruction by Prostate, Stricture, Cystocele DM, spinal cord injury Detrusor-sphincter dyssynergy 4. Functional severe dementia, depression, impaired mobility, environmental barriers
