目的 :探讨自制选择性输卵管再通导管的临床应用效果。方法 :5 0 4例经证实有一侧或双侧输卵管不通的不孕症患者 ,采用自制选择性输卵管再通导管进行再通。该导管由导向导管、锥头导管、微导管和导丝 4部分组成 ,导管头端据子宫形态分别弯曲成不同角度的 3种形态。对操作技术也进行了改进。结果 :5 0 4例中经子宫输卵管造影共发现 792支输卵管不通 ,共疏通 73 1支 ,总疏通率 92 .3 %。插管总成功率为 97.4%。发生输卵管穿破 2例 ( 0 .3 9% ) ,宫外孕 6例( 1.19% ) ,均明显低于国外报道。讨论 :采用自制选择性输卵管再通导管并在输卵管疏通过程中 ,应用宫颈牵引法、先冲后通法的操作手法 ,可提高输卵管再通的成功率 ,降低并发症的发生 Objective: To explore the clinical effect of self-made selective tubal recanalization catheter. Methods: A total of 504 patients with infertility confirmed as unilateral or bilateral fallopian tubes were recanalized with a homemade selective tubal recanalization catheter. The catheter is composed of a guide catheter, a conical catheter, a microcatheter and a guidewire 4. The catheter tip is bent into three different shapes according to the uterine shape. The operating technology has also been improved. Results: Of the 504 cases, 792 tubal obstruction were found through hysterosalpingography, 73 1 branches were dredged, the total dredging rate was 92.3%. Intubation assembly success rate was 97.4%. There were 2 cases (0.39%) of tubal perforation and 6 cases (1.19%) of ectopic pregnancy, which were significantly lower than those reported abroad. Discussion: The use of self-made selective tubal recanalization catheter and tubal clear process, the application of cervical traction method, the first red after the method of manipulation can improve the success rate of tubal recanalization and reduce the incidence of complications
