Preservation of Renal Function after Major Bleeding Events due to Ultrasound-Guided Parenchymal Renal Biopsy.

Clinical outcomes of major bleeding events following ultrasound-guided native and allograft parenchymal renal biopsy were evaluated. Forty-eight post-biopsy bleeding complications (Society of Interventional Radiology [SIR] adverse event grade ≥ 2) from 2002-2018 were identified. The primary outcome assessed was renal function. Clinical outcomes and interventions undertaken were noted including blood transfusion, angiography with or without embolization, nephrostomy tube placement, surgery, nephrectomy, hospitalization, intensive care unit admission, dialysis, and survival. Renal function may be moderately diminished in the short-term periprocedural setting. None of the patients studied died, had nephrectomy or dialysis initiated as a result of a renal biopsy bleeding complication.
