Based on the spontaneous migration of radioactive tracer from the posterior vaginal fornix to the ovaries and peritoneal cavity, several attempts were made to assess hystero-salpingo scintigraphy (HSS). The low acceptance rate by sterile women of routine investigation of tubal function may be due to a fear of radiation exposure and unpleasant examination procedures. Our protocol for HSS adopts a low dose of radioactive tracer (0.2-0.3 mCi), a defined mode of application (between the external and internal os of the cervical canal) and a short imaging time (60 min). From 1990 to 1992, we investigated 60 fallopian tubes in 32 sterile women by HSS, hystero-salpingography (HSG) and/or chromopertubation during laparoscopy (LPSC). The results of HSG and HSS corresponded in 15 of 49 fallopian tubes, LPSC and HSS in 9 of 24. None of the 32 patients had become pregnant naturally during the average observation period of 17 months. Two patients became pregnant after in-vitro fertilization. HSS, performed according to our protocol, causes less pain and results in a lower dose of radiation than HSG (about 50%). It is well accepted by patients and is easy to perform. As an investigation of tubal function, HSS may serve as an additional examination technique in cases of presumed tubal sterility.
