ABSTRACT
PURPOSE: To evaluate the efficacy and complications of ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun in patients with diffuse renal disease. MATERIALS AND METHODS: 203 ultrasound-guided renal biopsies using 18G automatic biopsy gun were performed in 197 patients for the diagnosis of diffuse renal disease. The success and complication rates were retrospectively evaluated by analysis of pathologic and clinical records and post-procedure ultrasonograms of the patients. RESULTS: Out of 203 renal biopsies, adequate tissues for pathologic diagnosis were obtained in 184 (90.6%) biopsies. The mean number of needle passes was 2.08, and the mean number of retrieved glomeruli was 7.71 +/- 4.23. Minor complications occurred in seven biopsies (3.45%) including asymptomatic macroscopic hematuria in five (2.45%) and small subcapsular hematomas in two (1%). No patients required transfusion or surgery because of biopsy-related complication. CONCLUSION: Ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun was an effective method for the pathologic diagnosis of diffuse renal disease and safe with low complication rate related to the procedure.
