Summary

Biofeedback therapy effectively treats staccato voiding in children, with most experiencing symptom relief or cure. Benefits are maintained long-term, with relapses managed by refresher courses.

Area of Science:

  • Pediatric Urology
  • Urodynamics
  • Pelvic Floor Dysfunction

Background:

  • Recurrent urinary tract infections (UTIs), wetting, and voiding dysfunction in children can stem from pelvic floor contractions causing staccato voiding.
  • Urodynamic evaluation is crucial for diagnosing overactive urethra during voiding in pediatric patients.

Purpose of the Study:

  • To assess the immediate and long-term effectiveness of non-invasive urodynamic biofeedback (BF) therapy for staccato voiding in children.
  • To determine if improvements in voiding dysfunction are sustained over time and to evaluate relapse rates.

Main Methods:

  • A historical follow-up study involving 31 neurologically normal children (aged 5-15 years) with urodynamically proven overactive urethra during voiding.
  • Biofeedback (BF) therapy was administered, and outcomes were assessed immediately and during a long-term follow-up (mean 4 years).

Main Results:

  • Twenty-four children (77.5%) benefited, with 16 (51.5%) cured and 8 (26%) showing significant symptom reduction.
  • Urinary flow normalized or nearly normalized in 77.5% of patients, though no correlation existed between subjective/objective improvements or initial urodynamic findings and outcome.
  • Long-term follow-up showed sustained benefits, with low relapse rates managed effectively by refresher courses.

Conclusions:

  • Urodynamic biofeedback (BF) is an effective treatment for staccato voiding and related voiding dysfunctions in children.
  • The positive effects of biofeedback therapy are largely maintained in the long term, with relapses being manageable.
