RESUMO
Objective To evaluate the effectiveness of an improved uterooperator in the interventional treatment of tube obstructional infertility, and to make a comparison with other motheds. Method 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 uterooperator(109 tubes), 20 with Cook cupped coaxial catheter (36 tubes), and 20 with emulsoid double-cavity tube (20 tubes). Result Among the improved uterooperator 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 uterooperator has the highest successful rate in selective catheterization(? 2=4.275 5, P
