Uretero-transappendix-cystoneostomy as a technique for the reconstruction of the lower part of the ureter

Background. Any large missing part of the ureter may be replaced by transureteroureterostomy, psoas hitch, Boari flap, nephrectomy, renal autotransplanation or by the implementation of an intestinal graft. Case report. A patient with a defect of the lumbal- pelvic portion of the right ureter, after the management of a penetrating and perforating gun shot wound was presented. The missing part of the ureter was successfully replaced with an appendix. The technique of uretero-transappendixcystoneostomy complete with a Boari flap and a psoas hitch was used. Conclusion. By the use of an original combination of surgical techniques, a large defect of the ureter and the defect of the bladder, as well as the preservation of the renal function was achieved in a more successful manner
