A Comparison between Kidney Allograft Biopsies Performed by Nephrologists and Surgeons Versus Interventional...

Area of Science:

• Nephrology
• Interventional Radiology
• Medical Procedures

Background:

• Renal biopsy is crucial for diagnosing kidney diseases.
• Traditionally performed by nephrologists and surgeons, ultrasound-guided renal biopsy is increasingly done by interventional radiologists.
• This shift necessitates evaluating procedural success rates.

Purpose of the Study:

• To compare the efficacy of renal biopsies performed by interventional radiologists versus nephrologists/surgeons.
• To assess the number of glomeruli and biopsy cores obtained by each group.
• To determine the number of attempts required for successful core acquisition.

Main Methods:

• Retrospective review of 378 consecutive renal biopsies.
• Comparison of outcomes between interventional radiology (IR) and nephrology/surgical teams.
• Analysis of baseline patient characteristics and procedural success metrics.

Main Results:

• Interventional radiology teams obtained significantly more glomeruli per biopsy (19.17 vs. 9.09, p<0.0001).
• More cores were obtained per biopsy by IR (2.42 vs. 1.57, p<0.0001).
• Fewer attempts were needed for IR to obtain one core (2.60 vs. 2.00, p<0.0001).

Conclusions:

• Renal biopsies performed by interventional radiologists demonstrate superior success rates.
• Enhanced training in renal biopsy techniques is recommended for nephrology fellows and surgery residents.
• Preserving procedural skills among non-radiology clinicians is essential.
