Successful management of catheter injury or refractory infection by partial replantation of peritoneal dialysis catheters: a retrospective observational study.
Observational study in BMC nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe revised 2023 guidelines from the International Society for Peritoneal Dialysis (ISPD) emphasize salvage methods for treating refractory catheter-related infections, or mechanical catheter damage. This approach preserves the existing catheter by manipulating only the outer cuff above the peritoneum, avoiding hemodialysis transfer. We investigated the effectiveness of the partial replantation technique.
methodsIn this retrospective single-center study (January 2021 - December 2023), outcomes for nine patients undergoing salvage methods were compared with 58 patients receiving de novo catheter insertion. We assessed exit-site infection (ESI), tunnel infection (TI), peritonitis, and catheter dysfunction. The salvage method entailed distal cutting of the impaired catheter and attaching a new segment using a connector with a PD adaptor and transfer set.
resultsNine patients (four males, mean age 56 years, average PD duration 66 months) employed the salvage method. Post-procedure, one patient (11.1%) reported ESI, one (11.1%) experienced TI, three (33.3%) developed peritonitis, and two (22.2%) required catheter removal. No procedural complications or catheter dysfunctions were observed. In the control group, ESI occurred in six patients (10.3%), TI in one (1.7%), peritonitis in 11 (19.0%), catheter removal in seven (12.1%), and catheter dysfunction in one (1.7%). Kaplan-Meier analysis showed no statistical difference between the groups: ESI (p = 0.306), TI (p = 0.094), peritonitis (p = 0.838), catheter dysfunction (p = 0.694), and catheter removal (p = 0.393).
conclusionsThis study supports the non-inferiority and effectiveness of the salvage method compared to de novo insertion in managing ESI or TI and mechanical catheter damage.
