ABSTRACT
Rupture of the peritoneal dialysis (PD) catheter is rare complication. Here, we report a case of catheter rupture that occurred because of exercise after partial catheter reimplantation.A 66-year-old man with a history of end-stage kidney disease secondary to diabetic nephropathy experienced refractory exit-site and tunnel infection. After the infected parts of the catheter were excised, a partial catheter reimplantation was performed. At the time of that surgery, a presternal location was selected for the new exit site, and a titanium extender was used to connect the two catheters. The patient was discharged on postoperative day 3, but was readmitted for a pericatheter leak 5 days later. Fluoroscopy performed to investigate the cause demonstrated a pericatheter leak from the connecting portion between the titanium extender and the catheter.Surgery performed to repair the leak revealed that the catheter had ruptured. We believe that the cause of the rupture was mechanical stress induced by the patient's stretching exercise program. The PD catheter was made of silicone rubber with high elasticity. Even when such resilient materials are used, we recommend that, to avoid PD catheter rupture after partial reimplantation, clinicians should discourage the patient from stretching excessively.
