Abstract: 【Abstract】Objective To investigate the feasibility, safety, method and effect of ultrasound-guided percutaneous insertion of peritoneal dialysis (PD) catheters. Method This retrospective study involved 23 patients who underwent ultrasound-guided percutaneous PD catheter insertion. Peritoneal puncture and the insertion of the PD catheter were guided by ultrasound. The patients were followed up for at least 6 months. The effect of ultrasonography to display the surgical procedure, technical success ratio, and incidence of complications including bleeding, intestinal injury, catheter displacement, blockage, leakage, encapsulation and peritonitis, and estimated technical survival rate of the PD catheters were evaluated. Results Ultrasonography could clearly display the surgical procedure. The technical success ratio was 100.0%. Catheter displacement occurred in one patient, and was corrected after conservative treatment. Change from PD to hemodialysis occurred in one case due to the poor dialysis adequacy. No other major complications were found. The estimated technical survival rates of the PD catheters at 6, 12, 18 and 24 months were 100.0%, 100.0%, 100.0% and 75.0%, respectively. Conclusions Ultrasound-guided percutaneous PD catheter insertion is a safe, feasible and minimal invasive method with better effects in short and medium terms.
