The megacystis microcolon intestinal hypoperistalsis syndrome: report of a case.

An infant girl with the megacystis microcolon intestinal hypoperistalsis syndrome is reported. The presence of polyhydramnios and the absence of upper urinary tract abnormalities, differentiate this patient from similar cases previously reported. Although the etiology of this disease is unknown, partial success with the use of bethanechol suggests that the deranged intestinal motility may be related to dysfunction of the autonomic nerve endings of the gut.
