OBJECTIVE: Artificial urinary sphincter has been used to treat urinary incontinence in children with neuropathic bladder, although there are few studies reporting very long-term results. We assess our experience over the last 27 years in the management of artificial urinary sphincter.
METHODS: A retrospective study was performed in patients with neuropathic bladder in whom an artificial urinary sphincter was placed in our institution between 1994 and 2020. Demographic variables, pre- and post-artificial urinary sphincter implantation urodynamic studies, long-term outcomes, and postoperative complications were collected.
RESULTS: An artificial urinary sphincter was implanted in 71 patients (median age 14.5; interquartile range 12.8-15.9), with a median follow-up time of 17.2 years (interquartile range 9.8-23.9 years). Thirty-nine patients underwent enterocystoplasty combined with artificial urinary sphincter placement and 32 underwent artificial urinary sphincter implantation alone, of whom 12 patients (16.9%) eventually required an enterocystoplasty because of unexpected bladder behavior changes, usually within 3 years of artificial urinary sphincter implantation. Adequate urinary continence was reported in 90.1% of patients, nine void their bladders spontaneously, and 62 need clean intermittent catheterization. Eighteen mechanical malfunctions occurred in 15 patients (21.1%), with an average artificial urinary sphincter working life of 15.1 ± 1.3 years. In five patients artificial urinary sphincter was removed due to infection or erosion. In 12 patients (30.8%), a continent catheterizable stoma was made (before or during the follow-up) because of problems with clean intermittent catheterization through the urethra.
CONCLUSION: The very long-term results of this study demonstrate that artificial urinary sphincter is an effective treatment for urinary incontinence in neuropathic bladder patients. Long-term follow-up is important to identify potential unexpected changes in bladder behavior in these patients.
