Dean GE, Kirsch AJ, Packer MG, Scherz HC, Zaontz MR. Antegrade and retrograde endoscopic dextranomer/hyaluronic Acid bladder neck bulking for pediatric incontinence. Journal of Urology. 2007 Aug;178(2):652-5. Epub 2007 Jun 15.
PURPOSE: Endoscopic bladder neck bulking techniques offer the potential for a relatively noninvasive cure for a difficult clinical problem. We review our experience using antegrade and retrograde approaches.
MATERIALS AND METHODS: A total of 34 children (18 boys and 16 girls, mean age 11.7 years) have been treated since March 2003. Of the patients 28 (82%) had neurogenic bladder and 6 had nonneurogenic sphincteric incontinence. Urodynamics confirmed low detrusor leak point pressures and adequate bladder capacity. Patients were treated with either a retrograde or an antegrade approach. In 82% of patients an antegrade approach was used and a posttreatment suprapubic tube was placed.
RESULTS: Mean followup was 11.7 months (range 3 to 31). Patients averaged 1.47 injections (range 1 to 5). Detailed followup of 19 patients revealed significant improvement in continence in 78% (mean 1.6 injections), with an average followup of approximately 1 year.
CONCLUSIONS: Our 31 months of experience with antegrade/retrograde bladder neck bulking demonstrates that it is a viable therapy for this group of children. While some patients have experienced prolonged success, re-treatment can be beneficial. The antegrade approach offers several advantages, including intraoperative leak point pressures, improved visualization and placement of a suprapubic tube to limit post-procedural remodeling.
