目的 :研究含铜硅胶V型节育器有无尾丝的临床效果。方法 :对 10 0 0例要求放环者随机分为 5 0 0例放置去掉尾丝的V铜型节育器和 5 0 0例放置有尾丝的V铜型节育器两组 ,放环后 3个月内 ,每次月经后复查 1次 ,此后每 3个月复查一次 ,随访 1年。结果 :带尾丝组要求取环者、脱环、性交疼均明显高于未带尾丝组。月经量增多两组间不明显。带尾丝组盆腔感染率亦明显高于无尾丝组 (P <0 0 0 1)。提示 :不留尾丝V铜型节育器可以减少副反应。
Objective: To study the clinical effect of copper-free silicone V-shaped IUD with or without tail wire. Methods: One hundred and ten patients who required ring release were randomly divided into 500 cases of V-copper IUDs with 100% removal of tail filaments and 500 V-copper IUDs placement of tail wires. After ring release, 3 Within a month, every menstruation after a review, then every 3 months after a review, followed up for 1 year. Results: In the group with tail thread, those who need to take the loop, the loop and pain were significantly higher than those without the tail thread. Menstrual volume increased between the two groups is not obvious. The pelvic infection rate in the pigtail group was also significantly higher than that in the pigtail group (P <0.01). Tip: Do not leave the tail wire V copper IUD can reduce side effects.
