Internal Pudendal Artery Injury during Prolapse Surgery Using Nonanchored Mesh

Herein is presented the case of a patient with stage 2 uterine prolapse treated surgically using nonanchored mesh. Complications were internal pudendal artery injury and a massive presacral hematoma that formed after surgery. Transcatheter arterial embolization was performed immediately, and the bleeding stopped. The patient subsequently experienced difficulty micturating and defecating because of presacral hematoma compression. Self-micturation and defecation capabilities were regained gradually at approximately 1 week after surgery. The hematoma resolved completely by 71 days postoperatively. Comprehensive knowledge of pelvic anatomy is important when performing surgery to treat prolapse using mesh kits. Removing the mesh and prophylactic antibiotic therapy is a means of conservatively managing a pelvic hematoma caused by prolapse surgery.
