Occult neurogenic bladder dysfunction (NVD) is common in children with anorectal malformations (ARM). Urodynamic evaluation revealed significant changes post-surgery, indicating potential long-term risks.

Area of Science:

  • Pediatric Urology
  • Gastroenterology
  • Neuroscience

Background:

  • Anorectal malformations (ARM) can be associated with neurodevelopmental abnormalities affecting the lower urinary tract.
  • Occult neurogenic bladder dysfunction (NVD) may be present in ARM patients without overt clinical or radiological signs.

Purpose of the Study:

  • To investigate the incidence of occult NVD in children with ARM using urodynamic evaluation.
  • To assess changes in neurovesical function before and after surgical correction of ARM.

Main Methods:

  • Prospective study involving 19 children with ARM, evaluated pre- and post-operatively.
  • Urodynamic studies were conducted using the Phoenix Griffon machine and Phoenix plus software.

Main Results:

  • Baseline urodynamics revealed diverse patterns, with only 21.1% showing normal capacity and compliance without uninhibited contractions.
  • Post-operative re-evaluation of 13 patients showed changes in urodynamic patterns in 76.9%.
  • Deleterious changes included new onset of uninhibited contractions (30.8%), decreased bladder capacity (23%), and reduced bladder compliance (15.4%).

Conclusions:

  • A high incidence of occult NVD exists in children with ARM, even without other detected abnormalities.
  • Surgical correction for ARM can lead to significant changes in neurovesical function, with potential long-term implications for upper urinary tract health.
