Severe cytomegalovirus ureteritis in a renal allograft recipient with negative CMV monitoring.

Cytomegalovirus (CMV) is a significant opportunistic pathogen in immunocompromised patients. Virus circulating in the donors or the recipients of solid organ transplants places the latter group at risk of developing CMV disease. The prevention of serious complications in them relies on defining potential risk factors and on the early detection of the presence and replication of CMV. We report a case of isolated CMV ureteritis, which developed into ureteric necrosis despite meticulous polymerase chain reaction (PCR)-based CMV monitoring.
