Dismembered pyeloplasty for post-traumatic ureteropelvic junction avulsion in a child.

Non - iatrogenic ureteral injury is rare because of the well-protected retroperitoneal location of the ureter with an incidence of less than 1%. Furthermore, isolated ureteropelvic junction (UPJ) avulsion as a result of acceleration/deceleration injury is extremely uncommon and may lead to significant morbidity if the diagnosis has not been made early using CT scan with delayed execratory phase. Endourological management of partial ureteric injuries is feasible, however, uretero-ureterostomy is the standard of care for complete upper ureteric injuries. We present a fourteen years old boy presented with UPJ avulsion secondary to blunt trauma treated with dismembered pyeloplasty approach.
