Role of magnetic resonance imaging in the pre‐surgical planning of perianal hidradenitis suppurativa, complicated by anal fistulae: A case report and review of the literature

Abstract

We report the case of an 18-year old woman presenting an inferior vena cava-calyceal fistula on a pelvic kidney revealed by chronic pelvic pain and recurrent pyelonephritis 6 months following an iatrogenic renal injury during an ureterscopy for renal stone. Retrograde ureteropyelography imaging showed a fistula between the upper calix and the inferior vena cava. First, the fistula was treated by open surgery, due to the recurrence, a total nephrectomy was necessary. We aims to emphasis an exceptionally rare surgical complication of ureteroscopy, as well as the treatment options.
