Update on the Native Kidney Biopsy: Core Curriculum 2019

Area of Science:

• Nephrology
• Pathology
• Medical Diagnostics

Background:

• Kidney biopsy has been the gold standard for diagnosing kidney diseases since the 1950s.
• Advancements in immunohistology and ultrastructural microscopy enhance diagnostic capabilities beyond light microscopy.
• It is a preferred method for obtaining critical diagnostic information for acute and chronic kidney diseases.

Observation:

• Kidney biopsy provides substantial diagnostic information with a relatively low risk profile.
• Potential complications include bleeding, gross hematuria, arteriovenous fistula, and perinephric hematoma.
• Percutaneous kidney biopsies are commonly performed using real-time ultrasound or CT imaging guidance.

Findings:

• Improved microscopy techniques offer more detailed insights into kidney disease etiology and classification.
• Biopsy results are integrated with serologic, urinary, and genetic testing for comprehensive diagnosis.
• The procedure is essential for diagnosing a wide spectrum of kidney pathologies.

Implications:

• Kidney biopsy remains a cornerstone in nephrology for accurate diagnosis and patient management.
• Understanding indications and potential complications is crucial for safe and effective procedural execution.
• Continued refinement of biopsy techniques and adjunct testing improves diagnostic yield and patient outcomes.
