Endoscopic treatment of urinary incontinence in pediatric patients: 2-Year experience with dextranomer/hyaluronic acid copolymer

Research output: Contribution to journalArticle

Abstract

Purpose: We investigated the effectiveness of dextranomer/hyaluronic acid copolymer (dextranomer microspheres in sodium hyaluronan solution) as a treatment for urinary incontinence due to sphincter incompetence in children and adolescents. Materials and Methods: Patients with urinary incontinence due to neurogenic and structural causes were given a transurethral injection of dextranomer/hyaluronic acid copolymer to increase bladder outlet resistance. Patients were assessed at 1, 3, 6, 12 and 24 months after injection using a validated questionnaire, 1-hour pad test, ultrasonography, cystography and cystometry. Patients who remained incontinent were offered repeat injections of dextranomer/hyaluronic acid copolymer up to a maximum of 3 injections. Results: A total of 16 patients 8 to 22 years old were treated with dextranomer/hyaluronic acid copolymer, including 3 with neurogenic bladder, 8 with bladder exstrophy after 3-stage reconstruction, 4 with penopubic epispadias and 1 with urogenital sinus. Mean volume injected was 2.8 ml. (range 1.8 to 4.0) and mean number of injections received was 2.3 per patient. Dry time interval increased by 43 minutes (p
