Radical surgery for treatment of primary localized bladder amyloidosis: Could prostate-sparing robot-assisted cystectomy with intracorporeal urinary diversion be an option?

摘要

Primary localized bladder amyloidosis is a rare pathology that mimics urothelial cancer. Systemic disease and lymphoproliferative disorders should be excluded. Transurethral resection is the mainstay of treatment, although in cases of extensive bladder involvement or massive haematuria radical cystectomy has been reported. To the authors' knowledge, this is the first robot-assisted prostate-sparing simple cystectomy with intracorporeal neobladder and preservation of the seminal vesicles and vas deferens reported in the literature, in a patient with primary localized amyloidosis of the bladder.
