Objective: To compare selective salpingography and balloon tuboplasty for the treatment of tubal obstruction.
Design: A retrospective evaluation of results of women treated for tubal obstruction by outpatient methods at a single center.
Setting: Tertiary-care, university-affiliated hospital.
Patient(s): A total of 3,424 infertile women, of whom 418 had bilateral tubal obstruction by hysterosalpingography, treated at Nihon Medical Center from 1982 to 1997.
Intervention(s): Women with tubal obstructions who had visual evidence of an intact uterine tubal ostium at hysteroscopy were treated by selective salpingography. If selective salpingography could not establish patency, then transcervical balloon tuboplasty was performed with one of three catheter systems. Patients were followed expectantly for 1 year after treatment.
Main outcome measure(s): Postoperative tubal patency and overall pregnancy rates (PRs) at 1-year of follow-up.
Result(s): The overall patency rate was 67.5%, with 30% of these patients conceiving (20.2% of all subjects). Selective salpingography was associated with a 35. 7% patency rate, and 27.3% of these patients conceived. Of the subjects who failed selective salpingography and underwent balloon tuboplasty, 66.2% achieved patency, of whom 33% spontaneously conceived. Balloon tuboplasty was effective in restoring patency in many cases after selective salpingography had failed. Statistically significant differences were found between selective salpingography and balloon tuboplasty and for the different balloon tuboplasty catheters in terms of patency rates, while a trend was seen for PRs.
Conclusion(s): Many women diagnosed as having tubal obstruction can be treated by outpatient methods that do not require general anesthesia. Achieving patency by these methods is associated with high PRs and avoids the need for assisted reproductive technologies in some cases. Balloon tuboplasty is a more effective treatment than selective salpingography. The choice of balloon tuboplasty catheter system may affect success rates.
