Methods According to the informed choice, follow-up was performed on the patients with unsupported IUD and other IUDs. The clinical effects and the incidence of adverse reactions were recorded. Results The success rate of placement of IUD without stent was 97.1% in 1039 cases, which was higher than that of other IUD placement (92.3%). The incidence of adverse reactions (28.87%) in non-stent-fixed IUD was lower than that in other types of IUD ).
