FIG1
The nephrostogram images revealed fibrosis of the entire transplanted ureter (Figure 1). Nephrostogram (Figure 1) showed complete occlusion at the level of the renal pelvis and no contrast passing to the ureter.
Nephrostogram performed intraoperatively showing the contrast delineating the extra-anatomical stent and filling the bladder. The arrow marks the approximate location of the exit from the kidney.

FIG2
The distal end was delivered to the bladder (Figure 2).
Prior to skin closure, the Detour stent was placed medially to avoid the scars and fibrotic tissues surrounding the renal graft.

Cystotomy was closed securely around the stent anchoring using the outer PTFE (polytetrafluoroethylene) tube of the Detour using interrupted polydioxanone sutures (Figure 3).
