TI - Amyloidosis and acute hemorrhage of the kidney, ureter, and bladder T2 - Canadian Journal of Urology PY - 2017 VL - 24 IS - 4 SN - 1488-5581 AB - Gross hematuria is a common occurrence in adults. The differential diagnosis is extensive, including: malignancy, trauma, infammation of the urinary tract, and stones. While, urinary tract amyloidosis represents only a small percentage of causative gross hematuria, it is concerning because of its superfcial resemblance to malignant processes. We report the case of an 82-year-old male with concurrent primary amyloidosis of the kidney, ureter and bladder in the setting of acute hemorrhage. Histopathological examination of several biopsied samples confrmed our diagnosis. A nephroureterectomy with bladder cuff was successfully performed without complication along with watchful waiting for the bladder amyloidosis.
