Abstract
OBJECTIVE: To determine the long-term effects of the periurethral expander, a new device for the treatment of urinary incontinence in children. PATIENTS AND METHODS: Twenty-five patients (mean age 11.2 years, range 3-22) had a periurethral expander implanted around the bladder neck within the last 41 months. Twelve of these patients had neurogenic bladders as a result of myelomeningocele, 12 had undergone unsuccessful exstrophy reconstructions and one had megalourethra. Bladder augmentations were carried out in 23 of the patients. The mean follow-up was 23 months. RESULTS: Ten patients had the device removed due to erosion and/or infection; patients with exstrophy were more susceptible to complications. Patients with neurogenic bladders use clean intermittent catheterization and the remainder void spontaneously. The mean pressure in the cuff was 58.7 cmH2O. CONCLUSION: The periurethral expander seems to be a valid option in the treatment of selected cases of urinary incontinence in children and young adults. There were more complications in patients with exstrophy/epispadias and such patients must be considered unsuitable for this treatment.
