Epidemiology

Prevalence increases with age.


Etiology

  • Pathomechanism: outlet incompetence
    • Urethral hypermobility: loss of pelvic floor musculature and/or connective tissue support → weak pelvic floor → inability of the urethra to completely close
    • Intrinsic sphincter deficiency
  • Risk factors
    • Multipara
    • Pregnancy and vaginal deliveries
    • High-impact activity (e.g., jumping, running, hopping)
    • Menopause
    • Obesity
    • Smoking
    • Chronic cough (e.g., COPD)
    • Prostate or pelvic surgery

Pathophysiology


Clinical features

  • Physical activity that causes increased intra-abdominal pressure (e.g., laughing, sneezing, coughing, exercising) leads to loss of urine
  • Frequent, predictable, small-volume urine losses with no urge to urinate prior to the leakage

Diagnostics


Treatment

Conservative treatment

  • Kegel exercises
    • Strengthen Levator ani
  • Lifestyle changes (e.g., weight loss, avoiding alcohol and caffeine, smoking cessation)
  • Vaginal pessary

Surgical procedures

  • Indicated if conservative treatment does not provide sufficient improvement of symptoms
  • Procedure of choice: midurethral sling to elevate the urethra
