Ultrasound-guided renal transplant biopsy: practical and pragmatic considerations

摘要

Sonographically guided percutaneous core biopsy of renal allografts has been performed for decades, providing valuable information in monitoring the status of normally functioning renal transplants as well as investigating the cause of renal transplant dysfunction. This article reviews practical aspects of biopsy technique using the cortical tangential approach, with consideration of factors that may influence biopsy success, including selection of biopsy device. Clinically important complications from renal transplant biopsy are uncommon; the most recent experience for one institution is analyzed in the context of existing evidence regarding the frequency and timing of these major complications, to understand pragmatic implications for peri-procedural care.
