[Isotope nephrographic studies in benign gynecologic diseases].

1014 patients with benigne gynaecological diseases (functional incontinence of urine with and without displacement, myoma of uterus, ovarian tumors, chronic salpingoophoritis) were examined by means of isotope nephrogram before gynaecological treatment was begun. A group of 156 patients was parallely examined by means of chromocystoscopy and intravenous urography. For judgement of the ING-curves we applicated an extra parameter--the drain value "A"--, through which it was possible to differenciate between emptying disturbances and functional urinary transport disorders. To obtain this value it is necessary to change the position of the patients during examination. Under these conditions approximately 95% of ING-findings conformed with those vaised by intravenous urography. Giving weight to these conditions, we recommend the application of ING in gynaecology as a screening method. Criteria for optimal usage of this method are mentioned.
