Nuestra experiencia con el catéter autoposicionante frente a otras variantes del catéter Tenckhoff: Estudio multicéntrico

introduction: the aim of the study was to compare the surgical, mechanical and infectious complications presented by self-locating catheters compared to other types of tenckhoff catheters, and to compare the survival of both types of catheter. material and methods: multicentre retrospective descriptive study lasting 79 months. all the catheters placed in two peritoneal dialysis units were studied. the analysis was carried out using the ibm spss statistics 19.0 statistical package, setting the significance level at p<0.05. results: the sample was made up of 241 catheters in 202 patients, of whom 52.5% were men (n=106). the average age was 61.98 + 15.87 years. the most used catheter was the self-locating catheter with 63.5% (n=153). surgical complications. surgical complications were only described in 28.1% of the self-locating catheters (p<0.001). mechanical complications. these were more frequent with the self-locating catheter, except for displacement, and were only significant for leaks (p=0.003). infections. a total of 196 peritoneal infections took place in 116 catheters, with a rate of 0.691 + 0.87 episode per patient per year. of these, 45.1% occurred in self-locating catheters, with no significant differences (p=0.214). causes for withdrawal. leaving pd represented 45.6% of the catheter withdrawals, 10% were due to peritoneal infection and 6.6% due to incorrect function. the self-locating catheter was removed in more cases due to leaks, peritoneal infections and incorrect function. survival of the catheters. we did not find differences in the survival of the catheters (log-rank mantel cox =0,164). discussion: self-locating catheters had a higher number of surgical and mechanical complications than the tenckhoff catheters, with no differences found in respect of infectious complications. we found a lower survival compared to the tenckhoff catheters without statistical significance. all the data seem to be related with the leaks caused by self-locating catheter
