Abstract
Urinary diversion is a common final outcome in patients with refractory long-term incontinence. It is even more common in young patients with neurogenic bladders and in such cases the bladder is disconnected and left in situ. We present a unique case of adenocarcinoma of the bladder which occurred 31 years following such a diversion procedure. We ask whether, despite the comorbidity associated with cystectomy, the patient is in danger of developing effectively silent tumours within these non-functioning bladders.
