We investigated the efficacy and tolerability of various anticholinergics in Korean children with non-neurogenic overactive bladder (OAB). A total of 326 children (males:females= 157:169) aged under 18 yr (mean age 7.3±2.6 yr) who were diagnosed with OAB from 2008 to 2011 were retrospectively reviewed. The mean duration of OAB symptoms before anticholinergic treatment was 16.9±19.0 months. The mean duration of medication was 5.6±7.3 months. Urgency urinary incontinence episodes per week decreased from 1.9±3.1 to 0.4±1.5 times (P<0.001). The median voiding frequency during daytime was decreased from 9.2±5.4 to 6.3±4.2 times (P<0.001). According to 3-day voiding diaries, the maximum and average bladder capacity were increased from 145.5±66.9 to 196.8±80.3 mL and from 80.8±39.6 to 121.8±56.5 mL, respectively (P<0.001). On uroflowmetry, maximum flow rate was increased from 17.6±8.4 to 20.5±8.2 mL/sec (P<0.001). Adverse effects were reported in 14 (4.3%) children and six children (1.8%) discontinued medication due to adverse effects. Our results indicate that anticholinergics are effective to improve OAB symptoms and tolerability was acceptable without severe complications in children.
