Insights

Electrical stimulation significantly lowers bladder pressure in children with neurogenic bladder. This non-invasive approach showed greater effectiveness in younger children, offering a promising treatment for managing bladder dysfunction.

Area of Science:

  • Pediatric Urology
  • Neurology
  • Biomedical Engineering

Background:

  • Neurogenic bladder (NB) in children, often caused by myelomeningocele, leads to overactive bladder and low bladder compliance.
  • Managing NB is crucial to prevent upper urinary tract damage and improve quality of life.
  • Urodynamic studies (UDS) are essential for assessing bladder function in these patients.

Purpose of the Study:

  • To evaluate the immediate impact of parasacral electrical stimulation on maximum bladder pressure in pediatric patients with NB.
  • To determine if electrical stimulation can effectively reduce bladder pressure during urodynamic studies.

Main Methods:

  • A nonrandomized intervention study involving 26 children (aged 5-15) with NB due to myelomeningocele.
  • Each participant underwent two UDS: one routine and one with parasacral electrical stimulation.
  • Maximum bladder pressure was compared between the two UDS, analyzed using a paired t-test.

Main Results:

  • 77% of patients exhibited lower maximum bladder pressure with electrical stimulation.
  • A statistically significant average reduction of 7.24 cmH2O in maximum bladder pressure was observed (P=0.04).
  • Children under 12 years showed a more pronounced pressure reduction (11.29 cmH2O, P=0.01).

Conclusions:

  • Transcutaneous electrical nerve stimulation (TENS) demonstrates a significant immediate effect in reducing maximum bladder pressure in pediatric NB patients.
  • The findings suggest TENS is a viable, non-invasive option for managing bladder pressure in this population.
  • Younger children (<12 years) experienced greater benefits from the electrical stimulation intervention.

Assessment of Neuromuscular Function Using Percutaneous Electrical Nerve Stimulation

We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).
