腹膜透析导管是腹膜透析的重要环节，导管相关性并发症约占腹膜透析转为血液透析原因的20%。不同类型导管由于结构和形状的不同，导致相关性并发症的发生率不同。双袖套较单袖套导管可更好地预防皮肤出口感染和腹膜炎；鹅颈管在预防隧道及皮肤出口感染上优于Tenckhoff直管；导管腹腔段卷曲型与直型比较，漂管及引流障碍的发生率更低。然而，随着透析技术和护理技术的提高，不同类型导管所致相关并发症的发生率均明显下降，已无明显差异。在重视导管类型选择的同时，更应强调皮肤和导管护理的重要性。

The use of catheter plays a critical role in peritoneal dialysis (PD). As many as 20% of the transfer from PD to hemodialysis is due to PD catheter-related complications. The incidence of PD catheter-related complications varies with the different structures and shapes of different catheter types. Double-cuffed catheter is better than single-cuffed catheter in reducing the rates of exit-site infection and peritonitis; Swan neck catheter provides better prevention of exit-site/tunnel infection than straight Tenckhoff catheter; the catheter with coiled intraperitoneal portion is associated with lower incidence of catheter-drifting and drainage-disturbance than the catheter with straight intraperitoneal portion. With the improvement of PD and nursing techniques, however, the incidences of various PD catheter-related complications have all been reduced, with no significant differences between the different types of catheters. Therefore, in addition to the selection of catheters, more attention should be paid to the nursing care of skin and PD catheter.
