Abstract
We report a case of renal salvage after total right ureteral loss using the isolated vermiform appendix with preservation of the blood supply. The appendix was used to bridge the gap between the right renal pelvis and left ureter. Followup revealed satisfactory function of the appendiceal conduit with preservation of renal function. The appendix, used in this fashion, is an attractive alternative to other surgical modalities after total or near total ureteral loss. The excellent contractility combined with the relatively small size eliminates the problems associated with urinary stasis and electrolyte reabsorption. However, its use is limited by its availability and length.
