Spontaneous dislodgment of a peritoneal dialysis catheter inserted using the Seldinger technique: A case report

Peritoneal dialysis (PD) is an important renal replacement therapy in patients with end-stage renal disease. PD catheters remain the lifeline for patients undergoing PD. The catheter technique survival rate is considered a core PD outcome domain. The PD catheter spontaneously dislodged in a patient undergoing PD during regular fluid exchange without pain. Abdominal computed tomography showed a tunnel infection. A double-cuff straight Tenckhoff catheter had been inserted using the Seldinger technique. Before this incident, the patient had a history of tunnel infections. We speculate that recurrent tunnel infections and catheter insertion using the Seldinger technique may have led to catheter dislodgement. The present case suggests that clinicians should more rigorously assess the persistence of catheter-related infections concerning the potential complications arising from catheter dislodgement associated with the Seldinger technique.
