An about 8 mm area of turbulent flow is visible in the lower third of the biopsied left kidney, demonstrated by both color and spectral Doppler. The kidney shows increased echogenicity and some smaller simple cysts. No perirenal or pelvic free fluid.
Case Discussion
Follow-up US of after kidney core biopsy is important, as iatrogenic AV shunts are not uncommon. Most resolve spontaneously, whilst in rare cases endovascular closure becomes necessary.
