Urinary incontinence in the elderly: pharmacologic therapies

Area of Science:

• Urology
• Geriatrics
• Pharmacology

Background:

• Acute urinary incontinence requires identifying and treating the root cause, which can range from infections and medication side effects to psychological factors like anxiety and depression.
• Chronic urinary incontinence presents in four main subtypes: stress, urge, overflow, and mixed, each necessitating a distinct therapeutic approach.
• Underlying conditions such as diabetes, prostatic enlargement, urethral stricture, and tumors can lead to overflow incontinence, often requiring surgical or interventional management.

Purpose of the Study:

• To outline the diagnostic and therapeutic strategies for managing acute and chronic urinary incontinence.
• To detail pharmacologic interventions based on the specific subtype of chronic urinary incontinence.
• To emphasize the importance of addressing underlying etiologies before initiating certain treatments.

Main Methods:

• Diagnosis involves identifying the underlying cause for acute incontinence and classifying chronic incontinence into one of the four subtypes.
• Pharmacologic treatments are selected based on the identified subtype of chronic urinary incontinence.
• Consideration of surgical correction or intermittent catheterization for overflow incontinence prior to specific pharmacologic agents.

Main Results:

• Stress incontinence can be managed with alpha-adrenergic agents that enhance sphincter tone.
• Urge incontinence, common in the elderly, responds to anticholinergic agents, smooth muscle relaxants, estrogen therapy, and potentially calcium antagonists.
• Overflow incontinence management is contingent upon resolving outflow obstruction or successful intermittent catheterization.

Conclusions:

• Tailoring treatment to the specific cause of acute urinary incontinence is crucial for effective management.
• Pharmacologic therapies for chronic urinary incontinence subtypes, including stress, urge, and overflow, offer targeted solutions.
• Addressing contributing factors and obstructions is paramount before implementing certain pharmacologic treatments for incontinence.
