title: Nonobstructive urinary tract dilatation in nephrogenic diabetes insipidus.
abstract: The follow-up study has been performed in 4 male patients with nephrogenic diabetes insipidus lasting for 4 to 15 years. Hydronephrosis or hydroureter appeared to be caused by polyuria with or without urinary tract obstruction. The efficacy of drainage operation is emphasized when polyuria surpasses the transporting ability of urine in the urinary tract.
