Urinary Incontinence Types
The four types differ by mechanism — and the exam answer is matching each to its first-line intervention: Kegels for stress, bladder training for urge, emptying for overflow, and access for functional.

Side by Side
| Type | Mechanism | Classic trigger / presentation | First-line intervention |
|---|---|---|---|
| Stress | Weak pelvic floor/sphincter; ↑ intra-abdominal pressure overcomes it | Leak with cough, sneeze, laugh, lift, exercise | Pelvic floor (Kegel) exercises; weight loss; pessary/sling if needed |
| Urge (overactive bladder) | Involuntary detrusor (bladder muscle) contractions | Sudden strong urge, then leakage; frequency/nocturia | Bladder training & scheduled voiding; anticholinergics/beta-3 agonist; limit bladder irritants |
| Overflow | Bladder over-distended and can't empty (obstruction or underactive bladder) | Constant dribbling; high post-void residual | Relieve obstruction; intermittent catheterization; treat cause (e.g., BPH) |
| Functional | Urinary tract intact, but a barrier prevents reaching the toilet | Immobility, dementia, restraints, environment | Prompted/timed voiding; accessible toileting; bedside commode |
Exam Traps
- ✦Stress = leak with cough/sneeze/lift → Kegels first; urge = sudden urge then leak → bladder training.
- ✦Overflow = constant dribble from a full bladder (high PVR) → relieve obstruction/catheterize.
- ✦Functional = the bladder works but the patient can't reach the toilet → prompted voiding & access.
- ✦Mixed incontinence is common (often stress + urge).
- ✦Incontinence is NOT normal aging — screen for reversible causes (DIAPPERS) and don't restrict fluids.
