    Summary

    Selective renal angiography guided percutaneous kidney biopsy is effective for tissue acquisition. Angiography identified bleeding in most cases, successfully managed with epinephrine infusion when necessary.

    Area of Science:

    • Nephrology
    • Interventional Radiology

    Background:

    • Percutaneous kidney biopsy is crucial for diagnosing renal diseases.
    • Selective renal angiography offers detailed vascular visualization for guiding biopsies.

    Purpose of the Study:

    • To evaluate the utility of selective renal angiography in guiding percutaneous kidney biopsies.
    • To assess the safety and efficacy of this imaging technique.

    Main Methods:

    • Fifteen patients underwent kidney visualization via selective renal angiography prior to biopsy.
    • Biopsies were attempted in 11 patients.
    • Post-biopsy angiograms were performed to assess for complications.

    Main Results:

    • Adequate renal tissue was obtained in all 11 biopsied patients.

  • Post-biopsy angiography showed pinpoint bleeding in 10 patients.
  • One patient had significant extravasation, managed with selective epinephrine infusion.
  • Biopsy was deferred in 4 patients due to thin renal cortex (<5 mm).

    • Conclusions:

    • Selective renal angiography is a valuable tool for percutaneous kidney biopsy, ensuring adequate tissue yield.
    • The technique allows for prompt identification and management of post-biopsy bleeding.
    • Careful assessment of renal cortex thickness is important for procedure selection.
