Prospective studies on applications of a two-cuff Swan neck catheter and a Tenckhoff catheter to Chinese CAPD patients

Aim: To compare the difference of clinical curative effects of continuous ambulant peritoneal dialysis (CAPD) patients in China by using a two-cuff Swan neck catheter and a Tenckhoff catheter. Methods: 110 patients with end-stage renal disease (ESRD) were enrolled. They were divided into Group A ( Swan neck catheter group, n = 55) and Group B (Tenckhoff catheter group, n = 55). One-year follow-up visits were made and information was recorded. Survival analysis was made by adopting the Kaplan-Meier method. Results: After 12 month follow-up visits, 17 patients had died, 3 had been transferred to renal transplantation, 8 had been transferred to hemodialysis, 3 were transferred to other hospitals, and the remaining 79 patients (71.8%) continued their peritoneal dialysis therapy in our hospital. 26 patients in both groups had peritonitis, with a total of 35 occurrences taking place. The total incidence of peritonitis was 0.32 times/patient year, with the detailed figure of 0.35 times/patient year for Group A and 0.29 times/patient year for Group B respectively (p > 0.05). Regarding mechanical complications of the 2 groups concerned, including catheter tip migration, Omental enwrapment, peritoneal dialysate leakage, skid of outer cuff, incidence of inguinal hernia and bellyache, etc, no significant difference existed between two groups ( p > 0.05). The two groups had the same 12-month technical survival rate of 92.73%. The 12-month survival rate for Group A was 86.34% while the corresponding figure for Group B was 80.68% ( p > 0.05). Conclusions: Infections, mechanical complications, technical survival rate and patients' survival rate were quite similar, when a Swan neck catheter and a Tenckhoff catheter were used in Chinese CAPD patients.
