Enhanced glomerular retrieval for renal biopsies

A substantial number of glomeruli were found to become dislodged from renal biopsy cores during the biopsy procedure. These ''lost'' glomeruli can be retrieved and immobilized on membrane substrates; the morphology of these membrane-immobilized glomeruli is of diagnostic quality. Hence, this technique of glomerular retrieval offers an opportunity to maximize the number of glomeruli obtained at biopsy and also makes available additional material for diagnostic studies, physiology studies, and archiving.
