[Immediate and late complications of hysterosalpingography. A comparison between Madsen's obturator and intrauterine balloon catheter].

Forty females who underwent hysterosalpingography (HSG) were randomized to a procedure using either an external cervical obturator or an intrauterine balloon catheter. All patients were interviewed about adverse events during and after the examination (six days). The balloon catheter turned out to be easier to place correctly and caused the fewest adverse events as regards bleeding and pain. It is concluded that a balloon catheter for HSG is preferable both from the doctor's and the patient's viewpoint.
