PURPOSE - Sacral neuromodulation for refractory urinary dysfunction in pediatrics shows promising results. We prospectively evaluated patients undergoing sacral neuromodulation using validated quality of life and bladder dysfunction questionnaires.

MATERIALS AND METHODS - All patients were prospectively enrolled in the study. Two validated questionnaires were completed preoperatively, after lead placement and at all followups. The PedsQL™ 4.0 Generic Core Scale, which assesses quality of life and bladder dysfunction, was quantified using the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome (NLUTD/DES) questionnaire. The Wilcoxon matched pairs test was used for statistical analysis with p <0.05 considered significant.

RESULTS - A total of 14 patients with a median age of 10 years were enrolled in the study. Median followup was 6 months. All patients underwent generator placement. No significant difference was seen in physical quality of life. Before and after lead placement mean ± SD psychosocial quality of life scores were 70.6 ± 17.4 and 81.43 ± 14.8 (p = 0.02), mean total quality of life scores were 75 ± 15.3 and 84.04 ± 13.2 (p = 0.006) and median NLUTD/DES scores were 23 ± 7.8 and 10.5 ± 7.0 (p <0.001), respectively. One month postoperatively a significant difference was seen in total quality of life and NLUTD/DES scores. Two patients required replacement of the temporary lead or generator. There were no infections.

CONCLUSIONS - Patients undergoing sacral neuromodulation had significant improvement in NLUTD/DES scores, and psychosocial and overall total quality of life. Results were durable at 1 month. Continuing to follow these patients in a prospective manner with validated questionnaires will strengthen the current evidence supporting sacral neuromodulation in the pediatric population.
