Psychogenic polydipsia with hydronephrosis in an infant.
Psychogenic polydipsia can occur in infants and may be associated with urinary tract dilation. It is not known whether this dilation can lead to a decline in renal function, as has been reported in patients with diabetes insipidus and hydronephrosis. The structural changes may be reversed by treatment of polydipsia through fluid restriction and counseling.
