Urodynamic changes after bladder augmentation surgery in paediatric patients with myelomeningocele due to neurogenic bladder

Abstract

Abstract Background Augmentation cystoplasty is a successful surgical procedure for the management of neurogenic bladder in children in order to improve urodynamic parameters. The aim of this article is to describe urodynamic changes after augmentation cystoplasty in children with myelomeningocele. Materials and methods A descriptive cross-sectional study including children aged 8–16 years with a myelomeningocele operated on for augmentation cystoplasty surgery with sigmoid colon segments due to a neurogenic bladder from the years 2003–2013. A urodynamic study was conducted before and after the surgical procedure. Non-probabilistic sample of consecutive cases. Descriptive statistics with frequencies and percentages, medians, and ranges. Inferential intra-group comparison with the Wilcoxon test and inter-group with Mann–Whitney U . SPSS 20.0 statistical package. Results The study included 50 patients, of whom 25 were male and 25 were female, with a median age of 12 years (range, 6–15 years). Bladder capacity improved from 52.8% to 95.9% ( p p 2 O and 11.0 cmH 2 O, respectively ( p 2 O ( p 2 O ( p Conclusions Augmentation cystoplasty with sigmoid colon significantly improved urodynamic parameters, such as bladder accommodation and filling pressure in children with myelomeningocele-associated neurogenic bladder.
