BK virus incidence, risk factors and its effect on mortality in hematopoietic stem cell transplant patients-single center experience

The aim of this trial is to investigate the risk factors of BK viruria and the effect of BK viruria on mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). The data of 247 patients who underwent HSCT between 01.01.2011-01.12.2017 in Inonu University Faculty of Medicine Department of Hematology were retrospectively analyzed.
