To examine the impact of peritoneal dialysis catheter configuration, curled or straight catheter, on catheter survival and mechanical and infectious complications.
Prospective randomized trial.
Department of Nephrology of a single university hospital.
Seventy-two consecutive patients initiating peritoneal dialysis were randomized to receive either a single cuff straight catheter or a single cuff curled catheter, implanted by percutaneous technique.
Significantly higher (p < 0.01) survival rate of the curled as compared to the straight catheter. The difference in catheter survival was due to a significantly higher (p < 0.01) incidence of drainage failure associated with catheter tip migration of the straight catheter than of the curled catheter. No difference in infectious complication between the two types of catheters was seen. Catheter survival at 12 months was 77% for the curled catheter and 36% for the straight catheter.
This study demonstrates superiority of the curled Tenckhoff peritoneal dialysis catheter survival as compared to the straight catheter. This difference in catheter survival is due to the higher displacement rate of the straight catheter.
探讨腹膜透析导管构型（卷曲导管或直管导管）对导管使用寿命以及机械性和感染性并发症的影响。
前瞻性随机试验。
一所大学医院的肾病科。
72例连续开始腹膜透析的患者被随机分为两组，分别接受经皮技术植入的单套囊直管导管或单套囊卷曲导管。
与直管导管相比，卷曲导管的生存率显著更高（p < 0.01）。导管生存率的差异是由于直管导管因导管尖端移位导致引流失败的发生率显著高于卷曲导管（p < 0.01）。两种类型的导管在感染并发症方面未见差异。卷曲导管12个月时的导管生存率为77%，直管导管为36%。
本研究表明，与直管导管相比，卷曲的Tenckhoff腹膜透析导管在使用寿命方面具有优越性。导管生存率的这种差异是由于直管导管的移位率更高。
