The key to successful long-term peritoneal dialysis (PD) is
permanent and safe access to peritoneal cavity. The two most
commonly used Tenckoff catheters for PO are the straight and
coiled catheters. The present study was undertaken to assess
the catheter survival, catheter associated infections, and all
cause mortality and to compare the straight with coiled catheters
in PD. During April 1997-August 2006, 96 patients undergoing
peritoneal dialysis in Ghaem Hospital, Mashhad,
Iran were enrolled in this study. In 53 patients straight catheter
and in 43 patients coiled catheter were used. The catheter survival,
and catheter associated infections including peritonitis
and exit site infection rate were compared between the two
groups. The catheter survival in the two groups was in favor of
coiled ones. Catheter associated peritonitis and exit site infection
were more prevalent in patients with straight catheters
(P=0.027 and P=0 .006 respectively). Overall patient survival
rate was not different between the two groups (P=0.919).
There was no difference regarding tunnel infection between
the two groups (P=0.673). Straight PD catheters were not associated
with more overall patient morality rate but less catheter
survival was noted in this group. In comparison with coi led
PD catheters, peritonitis and exit site infection were seen more
frequently in patients dialyzed using straight catheters. We
found no difference regarding leakage episodes (P =0.562) or
re-operation due to catheter malposition resulting in catheter
salvage (P =0 .26). Overall re-operation rate was not different
between the two groups (P =0.732). Straight PD catheters
were not associated with more patientsי morality rate but had
less catheter survival than coiled PD catheters. Peritonitis and
exit site infection were found more frequently in patients dia lyzed
with straight catheters.
