Postrenal-biopsy hematoma in infants and children: evaluation by ultrasonography.

Abstract

Postbiopsy hematoma was assessed using ultrasonography in 106 infants and children (age 1 month to 15 years) who underwent a total of 122 percutaneous renal biopsies. Postbiopsy hematoma occurred in 22 (21%) of 105 successful biopsies. However, only 2 of these were symptomatic. Renal failure, mild and moderate hypertension and inexperience of the operator were not found to increase the incidence of postbiopsy hematoma in infants and children.
