Randomized Controlled Trial Meta Analysis Comparative Study
Coiled versus straight peritoneal dialysis catheters: a randomized controlled trial and meta-analysis.
Variations in peritoneal dialysis catheter design include differences in numbers of cuffs, shapes of subcutaneous paths (swan neck vs Tenckhoff), and shapes of intra-abdominal segments (straight vs coiled). The relative benefits of these designs have not been studied adequately. The objective of this study is to compare the clinical outcomes of coiled- versus straight-end swan neck peritoneal dialysis catheters. ⋯ Although we were unable to show statistically significant differences in the primary outcome in our RCT, pooled meta-analysis results suggest that coiled catheters may be more prone to migration and resultant dysfunction.
