Renal parenchymal disease: sonographic-histologic correlation

H Hricak, C Cruz, R Romanski

    Radiology

    Summary

    Diagnostic ultrasound cannot distinguish between different renal medical disorders. While kidney length and cortical echogenicity correlate with some histologic changes, specific disease types remain indistinguishable by sonography.

    Area of Science:

    • Nephrology
    • Radiology
    • Pathology

    Background:

    • Renal parenchymal diseases encompass a range of kidney disorders affecting kidney function.
    • Diagnostic ultrasound is a non-invasive imaging modality used to assess kidney structure.

    Purpose of the Study:

    • To correlate sonographic kidney appearance with histologic changes and clinical findings in various renal parenchymal diseases.
    • To determine if diagnostic ultrasound can differentiate between different types of medical kidney diseases.

    Main Methods:

    • A retrospective analysis of 109 patients who underwent renal biopsy.
    • Independent and blinded review of clinical, pathologic, and sonographic data by multidisciplinary teams.

    Main Results:

    Related Experiment Videos

  • No correlation was found between specific sonographic appearance and renal disease type.
  • Renal length correlated with global sclerosis, tubular atrophy, and hyaline casts.
  • Cortical echogenicity correlated with global sclerosis, tubular atrophy, hyaline casts, and leukocytic infiltration.

    • Conclusions:

    • Diagnostic ultrasound cannot currently distinguish between different types of medical renal disorders.
    • While certain sonographic features correlate with histologic changes, they are not specific enough for disease differentiation.
