[Spontaneous extraperitoneal bladder rupture. Report of a case].

The spontaneous extraperitoneal bladder rupture is an uncommon event and the diagnosis is very difficult. It is defined like the rupture of bladder wall in absence of traumatism or iatrogenic techniques. The extravasation usually is produced into the peritoneal cavity, because of the greater weakness of the vesical dome. The diagnosis is based on the retrograde cystography, being necessary the surgical treatment in the intraperitoneal rupture, while the extraperitoneal one, could be treated in a conservative way with a vesical catheter. Here we present a case of spontaneous extraperitoneal bladder rupture, with oliguria, abdominal pain and a right hypochondrius mass as clinic presentation. Due to this, the diagnosis was made by the TAC, in which it was appreciated a continuity solution in the anterior bladder wall, with a contrast extravasation through the anterior abdominal wall. The retrograde cystography confirmed the definitive diagnosis. The treatment followed was based on the keeping of the vesical catheter and antibiotherapy.
