There are occasional reports of using the appendix to replace sections of the ureters, and to our knowledge, only a couple of them were in the left side.
We used the appendix as a ureteral substitute in two cases in technically difficult parts, the upper left ureter and the first part of the right ureter.
Follow-ups of 8 years and 6 months in right and left side cases, respectively, are impressive with maintenance of patency and improving renal function.
We believe that the use of the appendix is a valuable alternative to substitute all segments of both ureters, with good results.
