The efficacy and safety of an improved percutaneous peritoneal dialysis catheter placement technique in urgent-start peritoneal dialysis patients: a retrospective cohort study.

Background: Urgent-start peritoneal dialysis has high catheterization skill requirements and that early complications. The optimal catheter placement method remains debatable in urgent-start peritoneal dialysis patients. Safe and effective peritoneal dialysis catheterization is needed in clinical work.

Methods: We retrospectively analyzed the data of 34 patients diagnosed with end-stage renal disease who opt for peritoneal dialysis, 19 males and 15 females, with an average age of 62.3±14.7 years, peritoneal dialysis catheter implantation was completed by the improved percutaneous catheterization technique. They were followed for 6 months, early and late complications were observed and the survival rate of the catheter technique was calculated.

Results: All 34 patients diagnosed with end-stage renal disease successfully underwent catheter placement using the improved percutaneous technique; the catheterization success rate was 100%. No severe organ injuries, such as intestinal perforation and bladder perforation, occurred intraoperatively. Peritoneal dialysis was started immediately after surgery. The early complications included one case of leakage, one case of omental wrapping, and six cases of rectus abdominis hemorrhage. The late complications included one case of pleuro-abdominal fistula and two cases of peritonitis. The 6-month technical survival rate for the catheter was 94.1% (32/34). Compared to previously reported studies, this technique may reduce leakage and early catheter dysfunction, and improve the technical survival of catheters.

Conclusions: The improved percutaneous peritoneal dialysis catheter placement technique might be an effective and safe method for urgent‑start peritoneal dialysis patients.
