Medullary pathological findings provide additional prognostic information beyond cortical pathology in native kidney biopsies

Key takeaways

When a kidney biopsy is read, doctors mostly examine the outer layer, called the cortex. This study asked whether damage in the deeper part, called the medulla, tells you anything extra about how a person will do later. It found the deeper tissue added information beyond the outer layer alone. It is an observational study of biopsy samples, so it shows a link with later outcomes, not proof of cause, and the number of biopsies is not stated here.
