title: [Acute urinary retention in a pre-school girl with constipation].
abstract: OBJECTIVE
  To report a case of a preschool girl who developed acute urinary retention associated with constipation.
  
  
  METHODS
  A girl aged six years old presented a 24 hour history of inability to urinate. She was went twice to the emergency room during this period. In the first admission, 12 hours after the onset of the symptoms, she presented abdominal pain and acute urinary retention. After the drainage by urinary catheterization of 300 mL of clear urine, she presented relief of the symptoms and, as urinalysis had no change, the patient was discharged home. Twelve hours after the first visit, she returned to the emergency room complaining about the same symptoms. At physical examination, there was only a palpable and distended bladder up to the umbilicus with no other abnormalities. Again, a urinary catheterization was performed, which drained 450 mL of clear urine, with immediate relief of the symptoms. Urinalysis and urine culture had no abnormalities. During the anamnesis, the diagnosis of constipation was considered and a plain abdominal radiography was performed, which identified large amount of feces throughout the colon (fecal retention). An enema with a 12% glycerin solution was prescribed for three days. During follow-up, the child used laxatives and dietary modifications, this contributed to the resolution of the constipation. There were no other episodes of urinary retention after 6 months of follow-up.
  
  
  CONCLUSIONS
  Acute urinary retention in children is a rare phenomenon and constipation should be considered as a cause.
