Women experiencing sensory urgency or detrusor instability perceive bladder fullness abnormally, reporting higher fullness scores than controls. This altered perception may explain their symptoms and highlights similarities between these conditions.

Area of Science:

  • Urology
  • Neuroscience
  • Physiology

Background:

  • Sensory urgency is a common urological symptom.
  • The perception of bladder fullness in women with sensory urgency is not well understood.
  • Understanding bladder fullness perception is crucial for diagnosing and managing lower urinary tract symptoms.

Purpose of the Study:

  • To investigate if women with sensory urgency exhibit abnormal bladder fullness perception.
  • To compare bladder fullness perception between women with sensory urgency, idiopathic detrusor instability, and healthy controls.

Main Methods:

  • Prospective observational study involving 45 women (15 per group: sensory urgency, detrusor instability, control).
  • Cystometry was performed, with participants rating perceived bladder fullness using a visual analogue scale at various filling volumes.

  • Maximum bladder capacity and perception of fullness were the primary outcome measures.

    • Main Results:

    • Women with sensory urgency and detrusor instability had significantly lower maximum bladder capacities than controls.
    • Both sensory urgency and detrusor instability groups reported significantly higher perceived bladder fullness scores at 25%, 50%, and 75% of bladder capacity compared to controls.
    • No significant difference in perception was found between the sensory urgency and detrusor instability groups.

    Conclusions:

    • Women with sensory urgency and detrusor instability demonstrate an abnormal perception of bladder fullness.
    • This abnormal perception likely contributes to symptoms of frequency and urgency in these patient groups.
    • The findings support the clinical similarity between detrusor instability and sensory urgency.
