Comparison of conventional straight and swan-neck straight catheters inserted by percutaneous method for continuous ambulatory peritoneal dialysis: a single-center study.
OBJECTIVE
To evaluate the incidence of mechanical and infectious complications of conventional straight catheter (SC) versus swan-neck straight catheter (SNSC) implanted by percutaneous method.


METHODS
We retrospectively analyzed 45 catheter insertions being done by percutaneous method from January 1, 2011, to May 31, 2014. SC was inserted in 24 patients, and SNSC was inserted in 21 patients. Baseline characteristics for the two groups were similar with respect to age, sex and diabetic nephropathy as the cause for end-stage renal disease.


RESULTS
Incidence of mechanical and infectious complications in SNSC group was found to be low as compared to the SC group and was statistically significant (1 in 11.6 patient months vs. 1 in 14.4 patient months, p = 0.02). Catheter migration was found to be the most common mechanical complication (20 %), and peritonitis was found to be the most common infectious complication in conventional SC group (27 episodes in 420 patient months vs. 11 episodes in 333 patient months, p = 0.03). The incidence of exit site and tunnel infection rates revealed no difference between the groups.


CONCLUSIONS
SNSC insertion by percutaneous method is associated with low mechanical and infectious complications.
