Safety and utility of kidney biopsy in patients with estimated glomerular filtration rate 30 ml/min/1.73 m

Kidney biopsy (KBx) is the gold standard for evaluation of kidney disease, but is associated with a higher risk of complications in patients with reduced glomerular filtration rate (GFR). We studied the safety and utility of KBx in patients with eGFR30 ml/min/1.73 mConsecutive adult patients with eGFR30 ml/min/1.73 mOf the 126 patients included, 75% were male, 27.7% were diabetic, and the median eGFR was 13.5 ml/min/1.73mKBx is relatively safe in severe kidney disease but its risk to benefit balance needs to be carefully considered when eGFR is15 ml/min/1.73m
