Long-term efficacy of percutaneous tibial nerve stimulation for different types of lower urinary tract dysfunction in children

Purpose: We evaluated the efficacy of percutaneous tibial nerve stimulation for different types of pediatric lower urinary tract dysfunction. Materials and Methods: A total of 14 children with idiopathic overactive bladder, 14 with dysfunctional voiding, 5 with underactive bladder, 4 with underactive valve bladder and 7 with neurogenic bladder resistant to conventional therapy underwent percutaneous tibial nerve stimulation weekly for 12 weeks. The stimulation effect was evaluated by comparing bladder diary, flowmetry and urinalysis before and after treatment. Improved patients were followed by bladder diary and urinalysis. Followup data at 1 and 2 years were compared with those obtained after stimulation. Data were analyzed using Fisher's exact test. Results: Symptom improvement was significantly greater in nonneurogenic than in neurogenic cases (78% vs 14%, p
