Minimally Invasive Techniques for the Management of Adult UPJ Obstruction

Ureteropelvic junction obstruction (UPJO) is a common congenital abnormality that often presents in adulthood. Open dismembered pyeloplasty was considered the gold standard for the management of this condition; however, recent advancements in laparoscopic and robotic surgery have dramatically shifted the landscape to more minimally invasive techniques. A literature search of ureteropelvic junction obstruction, pyeloplasty, endopyelotomy, laparoscopic pyeloplasty, robotic pyeloplasty, and microlaparoscopic pyeloplasty was performed. A focus was placed on literature published since 2013. Minimally invasive laparoscopic and robotic techniques have become the gold standard for the management of UPJO. With the rise of robotic pyeloplasty, open repairs are becoming less frequent, while endoscopic treatments have remained stable. Minimally invasive (robotic) techniques have become the gold standard for the management of UPJO. Newer, even less-invasive techniques are also showing promise, but technical challenges still exist.
