Ureteropelvic junction obstruction repair can be performed in the first months of the infant’s life by means of videoscopic surgery. Two approaches can be used. First, the transperitoneal access offers a fairly large surgical space. On the other hand, it implies that the surgeon accesses a retroperitoneal organ by opening the posterior parietal peritoneum. To the right, kidney exposure may necessitate the detachment of the right colon and of the duodenum and the surgeon often has to lift up the right liver. To the left, the exposure of the ureteropelvic junction may require either a colonic detachment, or a transmesocolic opening by respecting the vascular supply of the left colon. The retroperitoneal approach is direct. It helps to better manage any potential urinary leaks, which will never occur intraperitoneally. It prevents any intraperitoneal dissection. However, it is a demanding technique technically speaking.
