Chronic infection, especially in the setting of obstruction
like calculous disease, may result in the fistula tract development
of fistula tract from kidney to the other proximal
organs. However, nephrocutaneous fistula is a rare
complication, and the primary cause of its development
is previous surgical intervention, trauma, or malignancy.
Our case was a 26-year-old Afghan man with xanthogranulomatous
pyelonephritis (XPN) resulted in spontaneous
nephrocutaneous fistula. The patient underwent radical
nephrectomy. Our case shows that previous surgery is
not the only cause of fistula.
