ADULT ENDOPYELOTOMY: IMPACT OF ETIOLOGY AND ANTEGRADE VERSUS RETROGRADE APPROACH ON OUTCOME

Abstract

Antegrade endopyelotomy is the preferred approach in patients with primary ureteropelvic junction obstruction and concomitant renal calculi (13.4% of cases), and may also be preferable in patients with high insertion obstruction (6.7%). For all other primary and all secondary ureteropelvic junction obstruction, antegrade and retrograde endopyelotomy is effective therapy yet retrograde endopyelotomy results in less operating room time, shorter hospital stay, fewer complications and significantly less expense to achieve the desired outcome.
