Risk Factors for Recurrent Ureteropelvic Junction Obstruction After Open Pyeloplasty in a Large Pediatric Cohort

Abstract

In this series lack of retrograde pyelography and dorsal lumbotomy were independently associated with a higher risk of recurrent ureteropelvic junction obstruction. While retrograde pyelography or a flank approach could not be directly shown to prevent recurrent ureteropelvic junction obstruction, electing to perform retrograde pyelography may be a proxy for better perioperative planning, including the choice of incision, and it may ultimately increase the chances of successful pyeloplasty.
