[Treatment of ureteropelvic junction obstruction in adult age].

Ureteropelvic stenosis, also known as ureteropelvic junction obstruction, is an obstruction in the region of the pyeloureteral junction resulting in a urinary discharge disorder of the renal pelvis, which requires treatment.Since the first description of pyeloplasty by Trendelenburg in 1886 and the successful establishment of open pyeloplasty by Anderson and Hynes in 1949, the treatment strategies for ureteropelvic junction obstruction have developed considerably, especially in the last two decades. Although open pyeloplasty is still considered to be the gold standard, this concept is supplemented by modern minimally-invasive techniques today. These include laparoscopic pyeloplasty, laparoscopic single-site pyeloplasty, robot-assisted pyeloplasty, robot-assisted single-site pyeloplasty, and endopyelotomy. This article provides an overview of the different treatment strategies for ureteropelvic junction obstruction as well as the complication management of pyeloplasty in adult age.
