^aRight nephrectomy, cystectomy and ileal conduit for vesicovaginal fistula secondary to irresectable pelvic disease.

^bRight antegrade stent inserted as two-stage procedure. Left side also treated with antegrade stenting 22 months after right side.

^cNephrostomy not converted to ureteric stent as unable to pass guidewire through stricture.

^dRetrograde stenting failed and patient renal function remained stable. Plans for antegrade stenting abandoned.
