According to the reporter, during a right ureteral reimplantation procedure, when the surgeon used the suture to fix the end of the ureter to the side wall of the left ureter, the suture needle broke and 2/3 of it was buried in the tissue, invisible to the naked eye.Under c-arm machine fluoroscopy, the stump of the suture needle was visible in the lower left abdomen.An electric hook was used to incise the side wall of the local bladder to search for the stump of the suture needle layer by layer, but the attempt failed.The search continued after the ureteral reimplantation was completed.Laparoscopy was used to search in the abdominal cavity.At the same time, the c-arm machine searched again, but still failed.A laparotomy was performed to explore.The patient's vital signs were unstable, and the surgeon, anesthesiologist, surgery center, and medical education department jointly decided to close the abdomen.The surgical time was extended due to the device problem.Five days after the procedure, the broken needle was removed by surgery.
