Abstract:
Ureteral injuries represent less than 1% of all traumatic genitourinary injuries. The rarity of traumatic ureteral injury is at least in part because the ureters are relatively well protected in the retroperitoneum. Ureteral injuries after blunt trauma are not common, and bilateral disruption of the ureteropelvic junction (UPJ) has only been previously reported in just one child. This is the first documented case of operative ureteral repair of bilateral complete UPJ disruption with double J ureteral stents in a child.
