Masquerading as A Stone: An Unusual Cause of Chronic Ureteric Obstruction

Abstract

Amyloidosis is a group of disorders characterized by the extracellular deposition of amorphous, misfolded proteins. Primary localized bladder amyloidosis is a rare form of the disease that usually presents with macroscopic hematuria, irritative lower urinary tract symptoms, or a bladder mass on imaging. Presented herein is a case of a 76-year-old female who presented with sepsis, distal ureteric calculus, and chronic ureteric obstruction without the classical symptoms of bladder amyloidosis. Cystoscopic resection of thickened bladder wall was positive for amyloid deposition with no signs of malignancy.
