To examine the impact of peritoneal catheter configuration on mechanical complications, catheter survival, probability of episodes of peritonitis, and probability of exit-site infections associated with the use of catheters for continuous ambulatory peritoneal dialysis (CAPD).
Prospective randomized trial.
CAPD unit in one university hospital.
Forty consecutive patients requiring a dialysis catheter for future CAPD were randomized to receive either a single-cuff straight Tenckhoff catheter or a permanently bent single-cuff Swan neck catheter. The skin exit was upward-directed in the Tenckhoff group and downward-directed in the Swan neck group.
Dialysate leak occurred in one patient and symptomatic catheter tip migration in 3 patients with the Tenckhoff catheter but in none with the single-cuff Swan neck catheter (p = 0.5, p = 0.12). No significant differences in catheter survival at 2 years, probability of episodes of peritonitis, or probability of exit-site infections could be demonstrated.
Catheter configuration did not influence the catheter-related mechanical or infectious complications. We were unable to demonstrate any advantage of the newer, permanently bent single-cuff Swan neck catheter over the conventional straight type.
探讨腹膜导管构型对持续非卧床腹膜透析（CAPD）导管使用相关的机械并发症、导管留存率、腹膜炎发作概率及出口处感染概率的影响。
前瞻性随机试验。
一所大学医院的CAPD病房。
40例因未来需行CAPD而需要透析导管的连续患者被随机分为两组，分别接受单套囊直型Tenckhoff导管或永久弯曲的单套囊鹅颈导管。Tenckhoff组皮肤出口向上，鹅颈组皮肤出口向下。
Tenckhoff导管组有1例患者发生透析液渗漏，3例患者出现有症状的导管尖端移位，而单套囊鹅颈导管组均未发生（p = 0.5，p = 0.12）。在2年的导管留存率、腹膜炎发作概率或出口处感染概率方面未显示出显著差异。
导管构型不影响与导管相关的机械或感染并发症。我们未能证明新型永久弯曲的单套囊鹅颈导管相对于传统直型导管有任何优势。
