Berdon syndrome is a disorder of the newborn, most prevalent in females, characterised by constipation and urinary retention, microcolon, giant bladder (megacystis), intestinal hypoperistalis, hydronephrosis, and dilated small bowel. The pathological findings consist of an abundance of ganglion cells in both dilated and narrow areas of the intestine. It is a familial disturbance of unknown aetiology. Authors disagree whether inheritance is autosomal dominant or recessive. more...
