Outpatient evaluation and treatment of tubal obstruction with selective salpingography and balloon tuboplasty

Objective: To compare selective salpingography and balloon tuboplasty for t he treatment of tubal obstruction. Design: A retrospective evaluation of results of women treated for tubal ob struction by outpatient methods at a single center. Setting: Tertiary-care, university-affiliate hospital. Patient(s): A total of 3,424 infertile women, of whom 418 had bilateral tub al obstruction by hysterosalpingography, treated at Nihon Medical Center fr om 1982 to 1997. Intervention(s): Women with tubal obstructions who had visual evidence of a n intact uterine tubal ostium at hysteroscopy were treated by selective sal pingography. If selective salpingography could not establish patency, then transcervical balloon tuboplasty was performed with one of three catheter s ystems. 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 c onceiving (20.2% of all subjects). Selective salpingography was associated with a 35.7% patency rate, and 27.3% of these patients conceived. Of the su bjects who failed selective salpingography and underwent balloon tuboplasty , 66.2% achieved patency, of whom 33% spontaneously conceived. Balloon tubo plasty was effective in restoring patency in many cases after selective sal pingography had failed. Statistically significant differences were found be tween 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 trea ted by outpatient methods that do not require general anesthesia. Achieving patency by these methods is associated with high PRs and avoids the need f or assisted reproductive technologies in some cases. Balloon tuboplasty is a more effective treatment than selective salpingography. The choice of bal loon tuboplasty catheter system may affect success rates. (Fertil Steril(R) 2000;73:1032-6.
