Radiologic usefulness of hysterosalpingography after bladder filling.

Berlin,Germany) was slowly injected, routine spot radiographs (anteroposterior.both oblique and latera] views) were obtained with fluoroscopic guidance. An additional anteroposterior view was obtained after instillation of 200 ml of saline solution into the bladder through a Foley catheter. For data analysis.the patientswere arbitrarily divided into two groups: anterior and posterior. The anteriorgroup was defined as the patients whose uterine axis was anterior to the sacral axis on the lateral view, and the posterior group was defined as the patients whose uterine axis was posterior to the sacral axis. Hysterosalpingograms before and after bladder filling were comparedfor changein uterine heightandchangein conspicuity of uterine abnormalities. Uterine height was measured from the fundus to the cervicoisthmic junction of the uterus on the anteroposterior view. Change in uterine height was assigned a uterine height ratio (after bladder
