[Isolated amyloidosis of the ureter. Apropos of a case and review of the literature].

Stenosis of the mid-portion of the right ureter and moderate hydronephrosis of the right kidney was seen on the intravenous pyelography of a 60-year-old patient consulting for sudden onset pain in the right inguinal region. Confirmation was obtained with retrograde urography and abdominal computed tomography. Right nephroureterectomy was performed. The pathology examination revealed characteristic features of amylosis located solely at the narrowing of the ureter. Isolated amylosis of the ureter is rare and difficult to diagnose.
