Peritoneal catheter survival and complications were determined
retrospectively over an eight-year period. Two hundred and twenty-two
peritoneal catheters were placed in 124 patients; the 107 failures, which
required catheter replacement, were due to dislodgment (38), one-way
obstruction (31), peritonitis (28), leakage (7), and tunnel infection (3).
Forty per cent of all catheter failures occurred within the first week due
mainly to dislodgment and obstruction. Females had significantly more
leakage-related catheter failures. Diabetic patients had fewer total catheter
failures and fewer failures due to peritonitis. Over a 24-month period no
difference was seen in the number or types of failures between straight and
curled Tenckhoff catheters. By life-table analysis cumulative per cent
catheter survival was 45% at 52 weeks; this was not affected by sex, type of
catheter, or use of radiography during placement. In patients with multiple
peritoneal catheter placements, subsequent catheters did not have a lower
survival.
KEY WORDS: Peritoneal catheter; peritoneal dialysis.
