BACKGROUND The practice of advising patients to stop antiplatelet agents before an elective renal biopsy is widespread. The aim of this study was to compare the rate of bleeding complications in two centres that have different policies regarding the ongoing use of antiplatelet agents in patients undergoing an elective renal biopsy. Neither centre routinely checks bleeding time before renal biop...

conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...

Despite the increasing use of alternative techniques, endomyocardial biopsy remains the primary method for diagnosing cardiac allograft rejection.
