ABSTRACT
Renal biopsy is an important tool for establishing the morphologic diagnosis and prognosis, as well as guiding therapy of renal disease in children and adults. Although a renal biopsy can be performed by an open surgical procedure, the percutaneous method is the preferred manner of obtaining the renal biopsy sample in most children. Although percutaneous renal biopsy of palpable tumors was rst performed in 1934 by Ball, the use of percutaneous renal biopsy for the diagnosis of medical disease was introduced by Iversen and Brun in 1951.1,2 Since then, the technique has been continuously enhanced by better guidance and instruments. e advent of real-time ultrasound and automated biopsy needles during the last two decades has simplied the procedure and further improved its success and safety.3
