and surgical procedure was performed with 2 stages procedure , as in adults . SNM was performed
using Interstim II, Medtronic. Patients were considered responders and non-responders, basing on
improvement of Urodynamics and clinical parameters such us voiding diaries, Post voiding residual
(PVR) or necessity of CIC. Statistical analysis was performed using SPSS.
RESULTS
26 children, with a mean age of 14.1 ± 3.07 years old underwent SNM implantation. 9 patients
with acquired NBD and 17 patients with congenital NBD have been included. An overall success
rate was observed in 81% of patients. Responders were most represented by acquired NBD
8/9 patients (88%) versus congenital NBD 13/17 (76.5%) , with at least 50% of urodynamics and
clinical improvement. The need of CIC in the 2 groups decreased from 3.67 ± 1.0 to 1.75 ± 0.95.
PVR improvement was observed in 30.7% of patients with congenital versus 57.1% of patients with
acquired NBD.
CONCLUSIONS
SNM is an effective treatment in paediatric patients with NBD. Our results suggest a better response
in acquired NBD.
