[Spontaneous rupture of the renal pelvis. A non-surgical acute abdomen (author's transl)].

The authors report a case of rupture of the renal pelvis in a young man, the course of which was spontaneously favourable over a period of a few days. No aetiology was determined, despite complete clinical, biological, pyelographic and arteriographic studies. The patient recovered completely without surgical or urological treatment. This condition is rare, 50 cases having been published in 1975.
