The optimal technique for peritoneal dialysis (PD) catheter insertion—percutaneous versus surgical—remains debated. Surgical placement offers direct visualization and fixation, whereas the percutaneous approach is minimally invasive, ambulatory, and facilitates urgent-start PD. We assessed the association between insertion technique and catheter functional survival, identified predictors of complications and catheter replacement, and compared long-term PD outcomes.
We conducted a retrospective observational study (2011–2025) including 491 incident PD patients. Variables included demographics (age, sex, etiology), technical factors (insertion technique: percutaneous or surgical), and clinical outcomes (complication type/classification, catheter replacement, PD program duration). Statistical analyses comprised Pearson’s χ² and Fisher’s exact test for categorical associations; Kaplan–Meier with Log-Rank for catheter and patient survival; multivariable logistic regression (Enter method) and Cox proportional hazards modeling to identify independent predictors. Significance was set at p<0.05.
Mean age was 57.6 ± 15.2 years; 60.9% were male; diabetic nephropathy predominated (68.6%). Insertion technique was percutaneous in 75.6% and surgical in 21.8%. Mean PD duration was 1,458 ± 921 days. Initial complications occurred in 33.6% (early mechanical 17.3%, early infectious 11.6%). A second catheter was required in 36.9% of patients; a third in 8.6%. No significant associations were observed between insertion technique and complication classification (χ²=12.6, p=0.126), specific complications (χ²=21.6, p=0.25), or need for a second catheter (χ²=3.95, p=0.139). Median catheter survival was 24 days (95% CI, 0–54) for percutaneous and 506 days (95% CI, 0–1021) for surgical placement (Log-Rank p=0.021). Overall PD survival was 2,528 days (95% CI, 2,210–2,845) with no difference by technique (p=0.808). By subtype, early infectious complications (peritonitis/tunnelitis) showed the strongest association with replacement (93%), followed by early mechanical (87%) and late mechanical (100%, small n). In multivariable logistic regression, complication classification was the only independent predictor (OR 0.25; 95% CI, 0.19–0.33; p<0.001; reference: no complications), whereas insertion technique was not significant (OR 0.89; 95% CI, 0.52–1.53; p=0.675). In Cox analysis, the hazard ratio for percutaneous versus surgical technique was 0.97 (95% CI, 0.72–1.31; p=0.83).
Insertion technique did not drive outcomes: percutaneous and surgical approaches yielded equivalent catheter and patient survival. Rather, early infectious and early mechanical complications determined replacement risk, while absence of complications reduced the odds by 75% (OR 0.25; p<0.001). These results shift the focus from how we insert to how we prevent early complications—emphasizing infection control, exit-site care, and proactive mechanical troubleshooting. Given its lower invasiveness and urgent-start feasibility, the percutaneous technique warrants broad adoption, alongside programmatic investment in complication-prevention bundles.
