Objective:

To evaluate the efficacy of extending transcutaneous tibial nerve stimulation (TTNS) treatment for pediatric overactive bladder (POAB) beyond the conventional 12 weeks to 24 weeks, emphasizing the identification of late responders and their clinical significance.

Key Findings:

• TTNS showed potential benefits in alleviating symptoms of POAB over the extended treatment period, with specific improvements noted.
• A subset of children demonstrated improvement after the initial 12 weeks, indicating the presence of late responders.
• The study highlights the need for further exploration of treatment duration effects in pediatric populations, particularly regarding long-term outcomes.

Interpretation:

Extending TTNS treatment duration may provide additional benefits for children with POAB, particularly for those who do not respond initially, suggesting a need for revised treatment protocols.

Limitations:

• The study was conducted in a single center, which may limit generalizability; future studies should consider multi-center designs.
• The absence of a control group restricts the ability to compare outcomes against standard treatment, highlighting the need for randomized controlled trials.

Conclusion:

Prolonged TTNS may offer incremental benefits for pediatric patients with OAB, suggesting that longer treatment durations should be considered in clinical practice to enhance patient outcomes.
