Ultrasonic localization for renal biopsy

Area of Science:

• Nephrology
• Medical Imaging
• Surgical Procedures

Background:

• Renal biopsy is a critical diagnostic procedure for kidney diseases.
• Accurate localization of the kidney is essential for safe and effective biopsy.
• Minimizing complications requires precise needle placement.

Purpose of the Study:

• To evaluate the utility of B-scan ultrasound for pre-biopsy kidney localization.
• To assess the feasibility and success rate of renal biopsy using ultrasound guidance.
• To compare ultrasound-guided localization with other established methods.

Main Methods:

• B-scan ultrasound was employed in 30 patients to visualize and outline the kidney.
• Longitudinal and transverse planes were used to determine kidney dimensions and depth.
• The puncture site and needle trajectory angle were determined based on ultrasound findings.

Main Results:

• Renal biopsy was successfully performed in 28 out of 30 patients (93.3% success rate).
• Ultrasound provided accurate localization, enabling precise needle insertion.
• The method demonstrated favorable outcomes compared to alternative localization techniques.

Conclusions:

• B-scan ultrasound is a reliable and effective tool for localizing the kidney before biopsy.
• This imaging modality simplifies the procedure and improves biopsy success rates.
• Ultrasound guidance offers a valuable alternative for renal biopsy localization.
