腹膜透析（PD）与血液透析（HD）相比，技术失败率较高是制约其发展的主要原因，其中导管故障是一个重要原因。腹膜内和腹膜外导管的配置可能与影响方法生存的机械和感染性并发症有关。我们报告两种腹膜外导管配置的经验：直管和天鹅颈状（SN）导管。共纳入85例连续患者，其中男性58例，女性27例。其中糖尿病患者26人；52例采用自动PD （APD）治疗，33例采用连续动态PD （CAPD）治疗。直管组38例，SN组47例。前6年多使用直管，后6年多使用SN管。两组的基线人口统计数据相似。SN组APD使用频率明显高于SN组。术中生存率优于术中生存率（log-rank检验，P = 0.01），患者生存率与术中生存率相近。我们组使用SN导管的患者有更好的技术生存率。另一个因素可能是该组APD使用频率明显较高。改变PD溶液的组成也有助于提高技术存活率。患者和使用的导管类型的结果相似。
Peritoneal dialysis (PD) is limited mainly by a higher technique failure rate as compared to hemodialysis (HD), catheter malfunction being an important reason. Intra- and extra-peritoneal catheter configuration may be associated with mechanical and infectious complications affecting method survival. We report our experience with two extra-peritoneal catheter configurations: the straight and the swan-neck (SN) catheters. A total of 85 consecutive patients, 58 males and 27 females were included in the study. Among them, 26 were diabetics; 52 were treated with automated PD (APD) and 33 with continuous ambulatory PD (CAPD). Straight catheters were used in 38 patients (straight group) and SN catheters in 47 patients (SN group). Straight catheters were mostly used in the first 6-year period while SN catheters in the last 6-year period. The baseline demographics were similar between the two groups. A significantly higher frequency of APD use was observed in SN group. Technique survival was better with SN versus straight (log-rank test, P = 0.01) while patient and catheter survival were similar. A better technique survival is noted in our group of patients with SN catheters. An additional factor could be the significantly higher frequency of APD use in this group. Changes in PD solutions’ composition could also contribute to improvement in technique survival. The outcome for patients and catheter types used was similar.
