These biopsies are performed by nephrologists and radiologists under real-time ultrasound guidance. A few studies have examined the outcomes of ultrasound-guided kidney transplant biopsy in transplant recipients; however, none have compared these outcomes between both specialties.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n We retrospectively analyzed a cohort of 678 biopsies performed in a single center during a 44-month study period. Biopsies were stratified into two groups based upon the specialist performing the procedure: interventional radiology (IR;\n N<\/jats:italic>\n =447) and transplant nephrology (TN;\n N<\/jats:italic>\n =231).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n There were 55 (8%) complications related to biopsies in the entire cohort: 37 (8.2%) in the IR group and 18 (7.7%) in the TN group, without statistical difference between the groups (\n P<\/jats:italic>\n =0.94). Blood pressure control and prior use of anticoagulation were significant predictors of complicated biopsies (\n P<\/jats:italic>\n =0.004 and 0.02, respectively). Being a woman and prior use of anticoagulation were significant predictors of transfusion of blood products (\n P<\/jats:italic>\n =0.01 and 0.01, respectively). Being a woman and blood pressure control were significant predictors of overall perinephric hematoma (\n P<\/jats:italic>\n =0.01 and 0.01, respectively), and Black race was a significant predictor of perinephric hematoma without worsening of renal function (\n P<\/jats:italic>\n =0.005). The specialist team performing the procedure was not a statistically significant predictor of biopsy complications, transfusion of blood products, or perinephric hematoma with comparable sample yield.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Percutaneous ultrasound-guided kidney transplant biopsy performed by transplant nephrologists have similar complication rates when compared with interventional radiologists in an academic center.<\/jats:p>\n
