A 45-year-old woman, gravida 3, para 3, comes to the clinic complaining of involuntary urine leakage for the past 4 months. She states that the leakage typically occurs when she coughs, sneezes, or laughs heartily. She does not experience a sudden, overwhelming urge to urinate prior to the leakage and does not wake up at night to void. Her medical history is unremarkable, and she had three uncomplicated vaginal deliveries. Physical examination reveals a positive cough stress test with leakage of urine from the urethra. Urinalysis is normal, and postvoid residual volume is 25 mL. Which of the following is the most appropriate initial management for this patient?
- Pelvic floor muscle exercisesAnswer
- BOral oxybutynin
- CMidurethral sling placement
- DOral bethanechol
- ETopical vaginal estrogen
Answer
Pelvic floor muscle exercises
This patient's presentation of urine leakage exclusively during activities that increase intra-abdominal pressure (coughing, sneezing, laughing), absent sudden urge, and normal postvoid residual is classic for stress urinary incontinence. The pathophysiology involves urethral hypermobility and/or intrinsic sphincter deficiency, often related to multiparity. The most appropriate initial, non-invasive management for stress urinary incontinence is strengthening the pelvic floor musculature (Kegel exercises) to improve active urethral support.
