Abstract: Peritoneal dialysis catheter is the basic foundation of peritoneal dialysis treatment. Reasonable selection of peritoneal dialysis catheter and standardized peritoneal dialysis tube placement are the keys to ensure its normal function. Current studies have shown that there is no significant difference in complications and outcomes among various peritoneal dialysis catheters, but it should be noted that the coiled-tail peritoneal dialysis catheters may increase the risk of catheter migration. Peritoneal dialysis catheterization methods include open surgical catheterization, percutaneous puncture catheterization, endoscopic / laparoscopic catheterization. Each method has its own advantages and needs to be selected according to the condition of patients and the technology of doctors. Ultrasound and radiation intervention technology can play an auxiliary role in peritoneal dialysis catheterization to ensure the success rate and safety. Advanced laparoscopic peritoneal dialysis catheter insertion can be used in patients with complex complication in the abdominal cavity. Reliable peritoneal dialysis catheterization technology and reasonable peritoneal dialysis prescription are helpful to reduce the occurrence of dialysate leakage in emergency start-up peritoneal dialysis.
