Etiology of ureteric trauma is mostly iatrogenic, in 18% is a blunt trauma and in 7% a penetrating trauma. Most of iatrogenic lesions are of gynaecologic etiology (73%), in 14 % of surgical and urological causes.
The most used diagnostic method is a CT urography or retrograde pyelography. The first steps of an ureteric reconstruction are the identification and excision or resection.
Therapeutic options are: temporary- ureteric stent, nephrostomy or definitive- primary uretero-ureterostomy, ureterocystoneoanastomosis, Boari flap, psoas hitch, trans-ureteroureterostomy, ureteric replacement using ileum ileal substitution.
