Minimal Invasive Approach for Lower Pole Uretero-Pelvic Junction Obstruction (UPJO) in Duplication Anomaly: A Multi-Institutional Study

Multi-institutional study of 41 pediatric patients demonstrates that laparoscopic and robotic-assisted pyeloplasty for lower pole UPJO in duplicated collecting systems achieves 93% success with minimal complications. Anatomic variability requires individualized surgical approaches including dismembered pyeloplasty, uretero-pyelostomy, or combined procedures.
