Intravesical electrostimulation in pediatric patients with spinal cord defects

Area of Science:

• Urology
• Pediatric Surgery
• Biomedical Engineering

Background:

• Managing neurogenic bladder in pediatric patients presents challenges in achieving low-pressure urinary storage.
• Current treatments like enterocystoplasty with intermittent catheterization are not always ideal.

Purpose of the Study:

• To evaluate the efficacy of intravesical electrostimulation in optimizing bladder storage for pediatric patients with neurogenic bladder.
• To assess if electrostimulation can improve continence and safe storage pressures.

Main Methods:

• A retrospective review of 44 pediatric patients who underwent bladder electrostimulation.
• Data analyzed included indications, age, bladder storage pressures, leak point pressure, and continence status before and after treatment.

Main Results:

• Indications for treatment included high bladder pressures (24), improved continence (13), and volitional voiding (7).
• Only 16% of patients achieved continence with safe storage pressures post-treatment; 9% met pretreatment goals.
• Non-responders often required surgical intervention for continence.

Conclusions:

• Intravesical electrostimulation provided limited benefit, sparing surgery for some but not most patients.
• The treatment did not consistently achieve spontaneous voiding at safe pressures.
• Predictors for successful intravesical electrostimulation treatment were not identified.
