Summary

Bladder neck mobility was assessed in healthy women. Bladder neck mobility was lower during coughing than during Valsalva maneuvers, indicating significant differences in pelvic floor support.

What harm does a second delivery to the pelvic floor?

European journal of medical research·2010

Area of Science:

  • Urogynecology
  • Pelvic Floor Imaging
  • Female Lower Urinary Tract Physiology

Background:

  • The mobility of the vesical neck is a key indicator of pelvic floor support and continence.
  • Understanding normal vesical neck mobility during physiological stress is crucial for diagnosing and managing urinary incontinence.

Purpose of the Study:

  • To evaluate the mobility of the vesical neck during coughing and Valsalva maneuvers in healthy nulliparous women.
  • To assess the reliability of perineal ultrasound for measuring vesical neck motion.

Main Methods:

  • A clinical observational study involving 39 healthy nulliparous volunteers.
  • Vesical neck motion was measured using perineal ultrasound.
  • Intra-abdominal pressure was monitored with an intrarectal probe, and intra-rater reliability was evaluated.

Main Results:

  • Vesical neck mobility was significantly lower during coughing (8 mm, SD 4 mm) compared to Valsalva (15 mm, SD 10 mm) (P < 0.005).
  • Individual mobility varied widely, from 4 mm to 32 mm during coughing and 2 mm to 31 mm during Valsalva.
  • Test-retest reliability showed maximum differences of 4 mm (coughing) and 5 mm (Valsalva).

Conclusions:

  • The bladder neck demonstrates significant mobility in continent women.
  • Bladder neck mobility is demonstrably lower during coughing than during Valsalva maneuvers.
  • Perineal ultrasound is a reliable technique for assessing vesical neck mobility.
