Idiopathic urinary bladder rupture in two mares

Abstract

Urinary bladder rupture is rarely reported in adult horses and is usually associated with parturition, history of trauma or urethral obstruction. This paper reports two cases in mares free of these predisposing factors, diagnosed through clinical manifestations, abdominal ultrasound and abdominocentesis, corrected by cystorrhaphy through laparotomy. While recovery was satisfactory in one case, the other case had complications in celiorraphy such as development of incisional hernia, small colon eventration and intestinal adherences, opting by the euthanasia of the animal. These reports are important because of the rarity with which they occur in adult mares. The different prognoses may be related to the severity of each case, according to the location and extension of the wound, which directly or indirectly influence the technique and recovery of the animals.
