Abstract

Objectives: This study aimed to investigate and compare the effectiveness of biofeedback (BF) therapy in the treatment of dysfunctional voiding (DV) and giggle incontinence (GI).

Patients and Methods: Between December 2022 and June 2025, medical records of patients who received BF therapy for DV or GI were retrospectively evaluated. Demographic and clinical data were recorded. Treatment success was evaluated as recommended by the International Children's Continence Society: No treatment response (0-49% improvement), partial treatment response (50-99% improvement), and complete treatment response (100% improvement). The success of BF therapy was compared in both diagnostic groups.

Results: A total of 60 patients completed biofeedback therapy, including 43 with DV (10 male, 33 female; mean age: 8.8 ± 3.1 years; range, 5 to 17 years) and 17 with GI (7 male, 10 female; mean age: 8.7 ± 3.0 years; range, 5 to 16 years). The overall complete treatment response was 68.3% (n = 41), and the partial treatment response was 20.0% (n = 12). Treatment success of DV and GI were similar (complete response: 67.4% vs. 70.6%, partial response: 20.9% vs. 17.6%) (p > 0.05). There was no significant difference between age and sex in terms of treatment success (p > 0.05 for both). Age, sex, and diagnosis revealed no association in predicting treatment efficacy or complete response in multinomial and binary logistic regression models (p > 0.05).

Conclusion: Biofeedback therapy demonstrated high and comparable success rates in children with DV and GI. Neither age nor sex was significantly associated with treatment response, supporting the potential role of BF in the management of both conditions.
