Vestigial to Wonders: Appendicular Interposition in Complex Ureteric Strictures

The case report aims to explore the role of the appendix as an interposition graft or flap for the reconstruction of right-sided ureteric stricture. We have used the appendix as a flap and as a complete interposition graft in two cases of right ureteric stricture, which are described in this paper. The appendiceal onlay flap was applied through robotic surgery, while an interposition graft was placed via a laparoscopic approach. Both cases resulted in good long-term surgical outcomes. The appendix, although a vestigial organ, can do wonders for the ureteric reconstruction in clinically complex cases.
