PG - 256-260 LID - 10.14740/jocmr3752 [doi] AB - BACKGROUND: Children with spinal cord disorders can present with neurogenic bladder, a condition in which the bladder partly or completely loses its ability to store urine and void at low pressure. A bladder with low compliance may cause urinary incontinence, which negatively impacts quality of life and renal function. Long-term high pressure neurogenic bladder can increase the risk of deterioration in renal function. Antimuscarinic pharmacotherapy with clean intermittent catheterization is currently considered one of the most effective treatments for these patients. However, some patients do not respond to oral medication or have unacceptable adverse events (AEs), which may result in medical withdrawal for these patients. Intravesical oxybutynin is an effective treatment with less AEs compared with oral medication. However, an important issue with this treatment is retention of the solution in the bladder. Moreover, as yet no data are available on the very long-term use and outcome of modified intravesical oxybutynin therapy. In the present study, we report on the efficacy, safety, and side effects of long-term modified intravesical oxybutynin therapy in children with neurogenic bladder. METHODS: Modified intravesical oxybutynin (1.25 mg/5 mL, twice a day) was administered to four children (three boys and one girl) with neurogenic bladder (detrusor overactivity and/or low compliance bladder), who were previously unresponsive to or experienced intolerable AEs from oral medications. Results of pretreatment cystometrograms were compared to those from follow-up urodynamic studies. Anticholinergic AEs, occurrence of urinary tract infection, and degree of incontinence during this treatment were also evaluated. RESULTS: After 1 year, bladder compliance improved in three of the four patients. After 3 years, detrusor overactivity was undetectable in all patients. Bladder compliance at 3 years and 10 years after initiation of therapy was similar for three patients, and they are continuing modified intravesical oxybutynin therapy. One patient discontinued therapy at 118 months due to worsening of bladder compliance and upper urinary tract infection. No anticholinergic systemic AEs were observed in any of the patients. CONCLUSIONS: These results suggest that modified intravesical oxybutynin is an effective and relatively safe long-term therapeutic option for children with neurogenic bladder.
