Abstract
We have developped a new replacable peritoneal catheter. In the treatment of catheter, it was easy for us to insert a new catheter into abdanial cavity. We had clinical datas and X ray findings during 2 years about 10 patients with a new catheter, 28 patients with straight typed catheter and 20 patients with curled type catheter. 39 percent in straight typed, 10 percent in curled typed, and 0 percent in a new catheter, were significantly out of adequte position in abdminal cavity. It was evidenced that no defect was not found in X ray photograph of a new catheter using urographin.
