Sphincter Weakness as the Mechanical Root of Stress Incontinence
Placeholder: weak pelvic floor and urethral sphincter cannot resist pressure.
- Sphincter: Mechanism (Placeholder short note)
- Exertion: Trigger type (Placeholder short note)
- Childbirth: Common cause (Placeholder short note)
- Small: Typical volume (Placeholder short note)
Sphincter weakness overview
Placeholder: brief note on urethral hypermobility and weak closure pressure.
Cough Test Reveals Leak Under Sudden Abdominal Pressure
Placeholder: standing cough test provokes visible urine loss.
- Cough stress test: Test name (Placeholder short note)
- Standing/supine: Position (Placeholder short note)
- Instant leak: Positive sign (Placeholder short note)
- Comfortably full: Bladder fill (Placeholder short note)
Provocation test protocol
Placeholder: brief note on performing and reading the cough stress test.
Detrusor Overactivity Drives Involuntary Bladder Contraction
Placeholder: detrusor spasms independent of bladder volume or exertion.
- Detrusor spasm: Mechanism (Placeholder short note)
- Spontaneous: Trigger type (Placeholder short note)
- Neurogenic/idiopathic: Common cause (Placeholder short note)
- Large: Typical volume (Placeholder short note)
Detrusor overactivity overview
Placeholder: brief note on urodynamic detrusor contraction spikes.
Sudden Strong Urge Precedes Urge-Type Leakage
Placeholder: abrupt compelling urge with little warning time.
- Abrupt: Onset (Placeholder short note)
- Seconds: Warning time (Placeholder short note)
- None: Link to exertion (Placeholder short note)
- Episodic: Frequency (Placeholder short note)
Urgency sensation pattern
Placeholder: brief note on urgency-frequency symptom clustering.
Voiding Diary Timing Separates Stress From Urge Patterns
Placeholder: diary correlates leaks with activity or sudden urge.
- Voiding diary: Tool (Placeholder short note)
- Activity-linked: Stress marker (Placeholder short note)
- Urge-linked: Urge marker (Placeholder short note)
- 3-day log: Duration (Placeholder short note)
Diary-based classification
Placeholder: brief note on combining diary entries with test results.
Placeholder: mixed pattern suggests both mechanisms are contributing.
