Finding the right position: a three-year, single-center experience with the self-locating catheter


Bergamin, B; Senn, O; Corsenca, A; Dutkowski, P; Weber, M; Wüthrich, R P; Segerer, S; Pechula Thut, M (2010). Finding the right position: a three-year, single-center experience with the self-locating catheter. Peritoneal Dialysis International, 30(5):519-523.

Abstract

BACKGROUND: Peritoneal dialysis (PD) catheter displacement is a major cause of dysfunction. Various catheter forms have been designed to improve outcome. One of them is based on the classical Tenckhoff catheter, but includes a small tungsten cylinder at the distal end to optimize location and to prevent dislocations. METHODS: In this retrospective study, we analyzed the functionality and complication profile of the self-locating catheter implanted at our center from November 2005 to September 2008 in our PD program. RESULTS: Data from 27 self-locating catheters implanted in 25 patients (12 women) were obtained. Patients were followed for up to 30 months (median observation time: 13 months), resulting in a cumulative study period of 357 PD months. A total of 22 complications were identified, including 1 episode of peritonitis per 52 patient-months, 1 tunnel infection, and 1 exit-site infection. The "functional catheter failure incidence rate" was approximately 0.01 catheters per month on PD (or approximately 1 catheter loss per 100 PD months). The catheter survival was 93% at 1 year. CONCLUSIONS: The "self-locating" PD catheter demonstrates low rates of catheter migration and dislocations, and good catheter survival.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
