[Renal vein thrombosis in childhood (author's transl].

The disease of renal vein thrombosis in children is presented on the basis of own observations and literature, whereby frequency, etiologic factors, and the age of manifestation are mentioned. The clinical symptoms are dependent on the localisation and the intensity of the thrombotic changes in the renal vein system which can be proven by the histological findings. The main symptoms of a renal vein thrombosis are hematuria, palpable enlargement of the kidney and pathological findings in the intravenous urography. Occasionally symptoms of an obliteration of the vena cava can appear, and in the complex disease picture a consumption coagulopathy can occur. The possibilities in therapy are pointed out, and above all, the question of the optimal time for a nephrectomy the most important point is discussed. In a self-observed newborn baby with unilateral renal vein thrombosis a relatively early nephrectomy-on the fifth day of life-a complete recovery could be achieved. The different opinions of thrombectomy are presented.
