Management of Overflow Incontinence

Understanding Overflow Incontinence

  • Overflow incontinence occurs due to bladder outlet obstruction or detrusor underactivity, causing incomplete bladder emptying and subsequent leakage, as reported by the European Association of Urology 1, 2

Clinical Pitfalls to Avoid

  • Failure to distinguish between different types of incontinence can lead to inappropriate medication selection, according to the European Urology guidelines 4
  • Not checking post-void residual volume before initiating antimuscarinic therapy in patients with suspected bladder outlet obstruction is a critical oversight, as noted by the European Urology guidelines 3, 4

Appropriate Management for Overflow Incontinence

  • Correct management of overflow incontinence should focus on addressing the underlying cause of bladder outlet obstruction and may include catheterization techniques, alpha-blockers for male patients with prostatic obstruction, and surgical interventions when appropriate, as recommended by the European Association of Urology 1, 2, 5
  • Alpha-blockers may be used in male patients with prostatic obstruction to manage overflow incontinence, as suggested by the European Urology guidelines 1, 5
