Enterolithiasis with imperforate anus: report of a case.

A three-year-old child presented with imperforate anus. A local perineal procedure was performed at birth, possibly without repairing the fistula. The child later presented with severe anal stenosis, which required a divided sigmoid colostomy. The child later presented at the age of two years with multiple radio-opaque shadows in the pelvis. These proved to be enteroliths, which had developed in the distal rectal stump possibly due to a large associated recto-urethral fistula with associated urinary stasis.
