Objective: Real-time sonographic guidance in conjunction with an automated core biopsy system is safe and effective method of performing percutaneous renal biopsy in children. Material and
Methods: We determinate the diagnostic adequacy and complication rates using smaller needle (16 gauge). Biopsies were performed on a total of 82 patients; 24 patients using 14 gauge needle (group 1) and 58 patients using 16 gauge needle (group 2) with an automated core bi-opsy device in the Department of Pediatrics at Şisli Etfal Hospital. Vital parameters have been observed 24 hours after biopsy.
Results: Adequate tissue for diagnosis was obtained in 21 of 24 patients (87%) in group I, and 54 of 58 patients (93%) in group 2. A total of 7 complications occurred in group 1 (29%), consisting of 1 perirenal hematom and 6 macroscopic hematuria and 12 complications occurred in group 2 (20%) consisting of 2 perirenal hematom and 10 macroscopic hematuria. Sample adequacy and complication rates were not significantly different between the two groups.
Conclusion: We assumed that the use of smaller (16 gauge) needle with an automated core biopsy system under real-time sonographic guidance would also provide low complication rates and adequate tissue for diagnosis in children.
