Percutaneous renal biopsy in children under guidance of ultrasonic real time technique

Percutaneous renal biopsy was performed under guidance of ultrasonic real time technique in 31 children, 3 to 17 years old. Ten of them had impaired renal function (GFR less than 80 ml/min X 1.73 m2). Three consecutive ultrasound examinations were performed during the first 24 hours after biopsy in 23 patients, who underwent renal biopsy after August 1980. Adequate renal tissue was obtained in 30 patients (97%) at first biopsy. An average of 26 to 27 glomeruli were obtained. 12.5% of the patients had gross hematuria and 12.5% had a small hematoma. None of them required blood transfusion or surgical intervention.
