Objective To minimize the adverse events of uterine compression suture in controlling postpartum hemorrhage (PPH) and to search for a prophylactic approach to potential PPH. Methods A retrospective analysis was performed in 39 women with removable retropubic uterine compression suture (RRUCS) to stop PPH due to uterine atony during cesarean section (CS). The procedure was to suspend and compress the uterus to the retropubic abdominal wall using an absorbable suture. Results The technique was sufficient to stanch bleeding immediately in 36 patients (92.31%, 36/39). No morbidity or abnormalities occurred in women who underwent RRUCS. Subsequent pregnancies occurred in 10 cases, but the others lacked the desire for future pregnancy. Conclusion RRUCS is a simple, safe, and effective technique in controlling atonic PPH; it is also used as a prophylactic application in patients with potential PPH after CS.
