One-liner
This episode provides a comprehensive review of urinary continence physiology and the three main types of incontinence—stress (pelvic floor weakness), urgency (detrusor overactivity), and overflow (detrusor underactivity)—along with the diagnosis of urethral diverticulum.
High-yield summary
- Stress Incontinence: Caused by increased intra-abdominal pressure (cough, sneeze) overwhelming weakened urethral support structures (e.g., post-vaginal delivery, obesity, estrogen deficiency). Diagnosis uses a positive Q-tip test (>30 degrees rotation).
- Urgency Incontinence: Characterized by a sudden, compelling need to urinate (urgency), often due to detrusor overactivity (Overactive Bladder/OAB) and is commonly treated with anti-cholinergic agents.
- Overflow Incontinence: Occurs when the bladder cannot empty completely due to detrusor underactivity or obstruction, resulting in high post-void residual (PVR) volumes (>100 mL). Treatment often involves muscarinic receptor agonists or catheterization.
- Urethral Diverticulum: Presents with dribbling of urine after voiding and has a temporal association with urination; it is an outpouching of the urethra.
- Physiology: Continence relies on balancing bladder contraction (detrusor muscle) against urethral closure (sphincter muscles), maintained by pelvic floor support.
Learning objectives
- Differentiate the pathophysiology and clinical presentation of stress, urgency, and overflow incontinence.
- Identify appropriate diagnostic tests (e.g., Q-tip test) for specific types of urinary leakage.
- Select appropriate pharmacological agents (anti-cholinergics vs. muscarinic agonists) based on the underlying cause of incontinence.
- Recognize the classic presentation of urethral diverticulum and its association with voiding.
- Understand the role of pelvic floor muscles and estrogen in maintaining continence, particularly in postmenopausal women.
