Endopyelotomy versus redo pyeoloplasty for management of failed pyeloplasty in children: A single center experience

Comparative study of 43 pediatric patients with failed pyeloplasty treated with either endopyelotomy (n=27) or redo pyeloplasty (n=16). Stricture length emerged as a key predictor: all failed endopyelotomies had strictures >15mm, while successful cases averaged 10mm versus 17.8mm in failures, suggesting redo pyeloplasty may be preferable for longer strictures.
