Previous studies have evaluated transjugular renal biopsy in patients with contraindications to percutaneous renal biopsy or those undergoing simultaneous renal and hepatic biopsies. We sought to evaluate transjugular renal biopsy in patients with acute renal failure (ARF) or ARF in the presence of chronic renal insufficiency (CRI) who required venous catheter placement for hemodialysis (HD). Ten consecutive patients (6 patients, ARF; 4 patients, ARF on CRI) at a single tertiary-care medical center, while undergoing placement of HD access through the internal jugular route, also underwent transjugular renal biopsy using the Quick-Core (Cook, Bloomington, IN) system to delineate the cause of ARF. Transjugular renal biopsy was performed because it was the opinion of the attending nephrologist that a histological diagnosis might alter management. Renal biopsy findings were diabetic nephropathy (3 patients), acute tubular necrosis (ATN; 2 patients), nephrosclerosis (2 patients), immunoglobulin A nephropathy (1 patient), lupus nephritis with focal crescents and ATN (1 patient), and pauci-immune necrotizing glomerulonephritis (1 patient). There were no major complications from the procedures. Among the 6 patients with ARF, management was directly affected in 3 patients (either initiation of appropriate immunosuppressive therapy or withholding of such therapy). In the remaining 3 patients with ARF and in patients with ARF on CRI, performing transjugular renal biopsy at the time of HD access placement obviated additional testing and/or unnecessary therapy. Four patients recovered renal function and HD therapy was discontinued, 2 patients died, and 1 patient was lost to follow-up. Simultaneous transjugular renal biopsy/HD catheter placement should be considered in patients with ARF requiring HD therapy for whom knowledge of the renal histological diagnosis may alter patient management.
