“…Above all, these two removable UCS can not only arrest PPH well, but also reduce the complications induced by the remaining thread. Comparing these two methods with ring compression suture (RCS), removable retropubic compression suture (RRCS) is more suitable for patients with uterine atony (UA), and removable suspension compression suture (RSCS) can be used for PPH caused by UA and placenta implantation in the corpus uteri; while RCS can be applied to preventing bleeding from the upper and/or the lower uterine segment, as it binds the uterus and the pubis together. Thereafter, we are going to put these two methods into practice by collecting more than 50 patients with each method.…”
