title: Ureteral stents: a novel risk factor for polyomavirus nephropathy.
abstract: Polyomavirus virus nephropathy (PVN) is an important cause of renal allograft dysfunction. The risk factors for the development of PVN have not been completely elucidated. We investigated the hypothesis that ureteral trauma caused by placement of indwelling stents is an independent risk factor for PVN. Twenty cases of PVN were compared with 46 controls. Logistic regression was used to calculate odds ratios and to construct multivariate models. A total of 75% of cases and 35% of controls had stents placed during renal transplantation. In both univariate and multivariate logistic regression analyses adjusting for age, gender, deceased donor transplant, delayed graft function, tacrolimus and exposure to antibodies, the placement of a ureteral stent at the time of kidney transplantation was found to have a statistically significant association with developing PVN. Our findings reveal that the presence of a ureteral stent is associated with an increase in the risk of PVN.
