Abstract:
PURPOSE:To evaluate in an experimental model, the mobility of a novel peritoneal dialysis catheter with a metallic tip (Mag-Cath) using an extra-corporeal magnet. MATERIALS AND METHODS:The Mag-Cath was installed in a porcine model under general anesthesia using laparoscopic access. A senior urologist, a urology resident, and a 3rd-year medical student were assigned to complete 2 tasks guided by fluoroscopy: (1) Move the catheter tip from the right flank to the pelvis and (2) move the catheter tip from the pelvis to the left flank. Accomplishment and time to complete the tasks were recorded. Participants were asked independently to grade the difficulty of the tasks using an analog scale from 1 (extremely easy) to 10 (extremely difficult). RESULTS:All participants completed the tasks. The difficulty of the tasks was graded equal to 1 by the senior urologist and urology resident and equal to 3 by the medical student. The time to move the Mag-Cath from the right flank to the target was 14, 10, and 55 s for the senior urologist, urology resident, and medical student, respectively. The time to move the Mag-Cath from the target to the left flank was 17, 18, and 43 s for the senior urologist, urology resident, and medical student, respectively. CONCLUSION:In this preliminary analysis, the use of an extra-corporeal magnet to move the Mag-Cath was feasible, with a low grade of difficulty, and individuals with different levels of expertise could perform it. Further studies in human subjects are needed to evaluate the clinical applicability of the Mag-Cath properly.
