Technology Based Treatment for UreteroPelvic Junction Obstruction

Surgical management of ureteropelvic junction obstruction (UPJO) has historically been performed with open pyeloplasty. With the advent of endourology, laparoscopy, and robotics, minimally-invasive techniques have been described and accepted as alternatives to open surgery. Each of these approaches has its own advantages and disadvantages, equipment needs, degree of invasiveness, and experience of the treating urologist. Advocates and critics have their own say as to their preferred technique. In this article, we review the chronological evolution of these techniques and discuss their current role in the management of UPJO.
