Ultrasound-guided percutaneous renal biopsy using the Bard Monopty device is safe and effective for children. This minimally invasive technique successfully obtained adequate tissue for diagnosis in most cases with minimal complications.

Area of Science:

  • Pediatric Nephrology
  • Interventional Radiology
  • Medical Devices

Background:

  • Percutaneous renal biopsy is crucial for diagnosing pediatric kidney diseases.
  • Minimally invasive techniques are preferred for pediatric procedures.
  • Existing biopsy methods may have limitations in terms of tissue yield or safety.

Purpose of the Study:

  • To evaluate the safety and efficacy of a specific technique for percutaneous renal biopsy in children.
  • To assess the utility of combining ultrasound guidance with a disposable automatic biopsy device.
  • To determine the adequacy of tissue samples obtained for diagnostic purposes.

Main Methods:

  • A cohort of 22 children underwent 25 percutaneous renal biopsies.
  • The Bard Monopty biopsy instrument, a disposable automatic device, was utilized.

  • Ultrasound guidance was employed throughout the biopsy procedures.

    • Main Results:

    • Adequate tissue for diagnosis was obtained in 24 out of 25 biopsies (96% success rate).
    • The procedure was associated with a low complication rate, including 2 small perinephric hematomas.
    • The Bard Monopty device facilitated efficient tissue acquisition.

    Conclusions:

    • The Bard Monopty biopsy device, coupled with ultrasonography, offers a safe and reliable method for pediatric percutaneous renal biopsy.
    • This technique provides sufficient tissue samples for accurate diagnosis.
    • It represents a valuable advancement in minimally invasive pediatric kidney diagnostics.
