[Rupture of simple renal cyst after minimal renal injury]. / Rotura de quiste renal simple tras traumatismo renal mínimo.

A case is presented of minimum renal trauma, leading to a retroperitoneal hematoma as a consequence of a simple renal cyst rupture as well as an artery contained therein. The etiopathogenicity of this phenomenon is commented. The different clinical manifestations of renal trauma are highlighted, as well as the suspicion of previous renal pathology when a large renal lesion is found secondary to minimum renal trauma. The approach of the renal pediculum must be the first step in the surgical treatment of renal trauma.
