Catheter Fixation Behind the Urachus: A Novel Laparoscopic Technique to Revise Malfunctioning Peritoneal Dialysis Catheters

Abstract

Peritoneal dialysis is one of the types of renal replacement therapy which is commonly used in patients with the end-stage renal disease. The cost-effectiveness and easy usage are the advantages of peritoneal dialysis. However, peritoneal dialysis is not always free of a problem and among all of its complications, catheter tip migration and omental wrapping are more common as are considered as the causes of catheter malfunctioning. Different techniques are used to correct the malfunctioning catheters such as manipulator techniques, laparoscopic repositioning with tip suturing, omentectomy and omentopexy. In this article, we are proposing two cases, which had been referred by peritoneal catheter malfunctioning and then received a new method of surgery successfully and didn't have any complications after 36 months follow up. This method could simplify the procedure of operation and urachus ligament and reduce time and cost of the process.
