The authors describe two children who had spontaneous extraperitoneal rupture of the urinary bladder into the retropubic space secondary to acute urinary retention following lower urinary tract surgery. One also had urinary ascites. In one, the urinoma was initially mistaken for the bladder during ultrasonography. In both cases, the diagnosis of bladder rupture was not considered initially because of a lack of familiarity with the occurrence of this entity in children.

Pulmonary edema after relief of airway obstruction due to laryngospasm is an uncommon but recognized entity. The authors report a case of a previously healthy young man who developed pulmonary edema after relief of laryngospasm following extubation of the trachea. Pulmonary edema after relief of acute airway obstruction should be included in the differential diagnosis of noncardiogenic pulmonary edema in the appropriate clinical setting.
