A retrosigmoid ileal conduit might prevent ureteroileal anastomotic stricture after ileal conduit diversion

Ureteroenteric anastomotic (UEA) stricture remains a significant complication after continent or incontinent urinary diversion. Most commonly, the left ureteral implantation is affected, which is thought to be caused by a wider mobilization of the ureter (1). The retrosigmoid tunnel may also increase the risk for angulation and/or compression of the left ureter. In this study (2), the authors presented their results with a technique involving the retrosigmoid transposition of the ileal conduit from the right to the left side of the body in order to avoid the problems associated with the crossing of the left ureter to the right side.
