Urinary tract dilatation and oral contraceptives.
Six nulliparous patients were found to have overdistensiblity of the upper urinary tract on excretion urography. Of these five had had persistent or recurrent urinary infections. All had been or were receiving oral contraceptives. Though overdistensibility associated with contraceptive therapy is unlikely to be life-threatening, it may be associated with increased patient morbidity.
