[Transvenous kidney puncture. New procedure for withdrawal of kidney tissue]

A transvenous catheter technique for renal puncture is described which was successful in 9 of 11 punctures performed in 8 dogs. Macrohematuria was not observed in any case. Autopsy revealed only small subcapsular hematomas. The advantage of this procedure is the reduced risk of bleeding achieved by peripheral puncture and by-passing of the great central vessels with aid of phlebographic controls. Moreover localization of kidneys by excretion urography--impossible in patients with renal insufficiency--is unnecessary.
