Association of micropapillary urothelial carcinoma of the bladder and <scp>BK</scp> viruria in kidney transplant recipients

Abstract

In one of the cases, BKV integration into the host genome was identified, leading to the truncation of the major viral capsid gene. This finding raises the concern that persisting BK viruria may be a risk factor for this aggressive form of bladder cancer. Further studies to determine screening and management strategies are required.
