Abstract
-
PURPOSE: To evaluate the diagnostic efficacy and complications of ultrasound-guided percutaneous renal biopsy
using automatic biopsy gun in patients with pediatric diffuse renal disease.
MATERIALS and METHODS
Using an 18G automatic biopsy gun, biopsies were performed on 97 pediatric patients
with clinically suspicious diffuse renal disease. The acquired tissue specimens were analyzed by photomicroscopy,
immunofluorescence, and electron microscopy to support the diagnosis. In the 97 biopsies, the success
of the histologic diagnosis, number of glomeruli, and complication rates were retrospectively evaluated by
analyzing the variable exams and clinical records.
RESULTS
Adequate tissue for histologic diagnosis was obtained in 91 of 97 biopsies (94%) and the mean number of
glomeruli was 9.6. Complications such as minute pain, gross hematuria, and small perirenal hematoma presented
in 22 of the 97 biopsies (23%), all of which either improved within 5-72 hours or did not need specific treatment.
CONCLUSION
Ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun is an effective and
safe method for the histologic diagnosis of pediatric diffuse renal disease without any major complication.
