Abstract:
Primary localized amyloidosis of the urinary tract is very rare disease. A 72-year-old man, with a history of urethral injury, had a stricture of the anterior urethra about 6cm in length. A segmental resection of urethra and urethroplasty, with penile skin flap, was performed. The resected urethral segment was diagnosed as urethral amyloidosis. There was no involvement of amyloidosis oin the other organs (heart, gastrointestinal system, joint, kidney, skin etc) and no underlying disease (multiple myelomas, rheumatism, cancer, chronic inflammation etc). Also, a 75-year-old woman, with a history of intermittent gross hematuria, had a stricture of the lower ureter. During diagnostic ureteroscopy, there was an irregular mucosal change of her lower ureter. An intraoperative biopsy showed ureteral amyloidosis. Here, we report on these two cases of primary amyloidosis of the urinary tract.
