    Abstract:
    Extended catheters with an upper abdominal exit-site (UAE) are reportedly associated with a lower incidence of peritoneal dialysis (PD)-related infections. However, little information about the optimal peritoneal catheter configuration for UAE is available. In this nonrandomized multicenter trial, 147 consecutive cases of a UAE involving either a conventional straight (CS; 80 cases) or extended swan-neck catheter (SN; 67 cases) were analyzed to compare exit-site and tunnel infections (ESTI), peritonitis, and catheter survival. The ESTI-free and catheter survival rates were significantly lower in the SN than in the CS group (P <0.01). However, the peritonitis-free survival rate was not different (P = 0.26). In terms of analyses for infection rates, fewer episodes of ESTI (1.284 vs 0.608 episodes/patient-year; P <0.01) and peritonitis (0.345 vs 0.152 episodes/patient-year; P = 0.06) were observed in the SN than CS group. Recurrence analyses showed that the mean number of cumulative episodes of ESTI and peritonitis between two groups were significantly different.
