Observations on Percutaneous Renal Biopsy in Children

Abstract
Observations on 100 consecutive percutaneous renal biopsies performed on children are recorded. Of the 80 children whose kidneys were examined, 18 were under 2 years of age. The technique with simple modifications, is described, and a comparison of anesthetic methods is made, favoring the use of sedation and local analgesia. The overall failure rate in this series is 9%, or 6.2% if three patinets in whom failure was followed by successful repeat biopsy are excluded. With sedation and local analgesia it is less than 2%. These results are compared with those of other workers. The risks of renal biopsy are discussed and two deaths are reported, one unrelated to biopsy, the other associated with the use of general anesthesia.
