Glomerular Yield in Ultrasound-Guided Native Kidney Biopsies in Pediatric and Adult Populations With Age-Stratified Subgroups

Pediatric patients exhibit a higher glomerular yield per biopsy core compared to adults, with no significant difference in the number of biopsy cores obtained. Among adults, younger patients (>18 to 40 years) demonstrate a higher glomerular yield compared to older age groups, suggesting that age may influence glomerular density and biopsy outcomes. Complication rates were low across all age groups, with no significant differences observed. These findings highlight the importance of considering age-related factors when performing native kidney biopsies to optimize diagnostic yield and minimize complications.
