Primary bladder amyloidosis--case report of a patient with delayed upper urinary tract obstruction 3 years after the diagnosis.
Primary bladder amyloidosis is a rare disease. There are approximately 100 reported cases. The lesions can be confused with bladder neoplasm and are characterised histologically by the classical apple green birefringence under polarised light. In this article, we report a 51-year-old lady with known history of primary bladder amyloidosis presenting with gross hydronephrosis 3 years after the first diagnosis. Laparoscopic ileal replacement of bilateral ureters was performed. There was no recurrent ureteric obstruction 2 years after surgery. This case demonstrates the progressive nature of primary amyloidosis of bladder. The diagnosis of primary bladder amyloidosis warrants long-term surveillance of upper urinary tract.
