Over the last two decades, we have seen a significant paradigm shift for the treatment of ureteropelvic junction (UPJ) obstruction. While initially the only treatment option was an open surgical approach, the decades have shown an evolution towards less invasive therapies. The move towards minimally invasive surgery was attributed to the significant morbidity associated with an open flank incision. This has led to the growth of laparoscopic and endoluminal surgical options that provide the potential for decreased morbidity: less blood loss, less pain, shorter hospitalizations, and faster recovery.
