Clinical application of an improved utero-operator in the interventional treatment of infertility

Objective: To evaluate the effectiveness of an improved utero-operator in the interventional treatment of tube obstruction infertility, and to make a comparison with other methods. Methods: One hundred cases of infertile women with tubal obstruction were divided into 3 groups and treated separately under TV fluoroscopy with 3 different methods and follow-up examination was made up to 24 months. Among the 100 cases, 60 cases were treated with improved utero-operator (109 tubes), 20 with Cook cupped coaxial catheter (36 tubes), and 20 with emulsoid double-cavity tube (20 tubes). Result: Among the improved utero-operator group, Cook cupped coaxial catheter group, and emulsoid double-cavity tube group, the successful rate of selective catheterization was 92.7%, 80.6% and 80.0%, respectively. The successful rate of recanalization was 72.3%, 72.4% and 71.4%, respectively. The pregnancy rate was 36.4%, 35.7% and 36.4%, respectively. Improved utero-operator has the highest successful rate in selective catheterization (x2 = 4.275, P < 0.05). Conclusion: Improved utero-operator has a high successful rate of selective catheterization in selective salpingography and treatment of tube obstruction infertility, and it is an easy and stable method which spends less time and received less X-ray. It is an ideal treating method at the moment
