Bladder rupture causing pseudo acute renal failure

Luciana Andrea Avena Smeili, Elizabeth In Myung Kim, Carlos Eduardo Marcello, Leonardo Bianqui, João Augusto dos Santos Martines, Américo Toshiaki Sakai


Bladder rupture is a rare condition associated with significant morbidity
and mortality. It is classified into traumatic, nontraumatic or idiopathic and
spontaneous. The nonspecific initial clinical presentation is followed by
discomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratory
abnormalities simulate the picture of acute renal failure and occurs by a
mechanism called auto reverse dialysis, with absorption of excreta through
the peritoneal membrane. The authors describe a case of bladder rupture
in morphologically and functionally normal urinary bladder associated with
alcohol intake in young healthy man, manifested by abdominal discomfort,
pseudo renal failure and massive ascitis. The diagnosis was made by an
abdominal multidetector computed tomography confirmed by the finding of
7 cm laceration at laparotomy.
