摘要

Drainage failure during peritoneal dialysis is most commonly due to mechanical complications, such as catheter migration and obstruction. However, intraperitoneal catheter rupture is extremely rare. We report the case of a 48-year-old man with autosomal dominant polycystic kidney disease (ADPKD) who developed intraperitoneal catheter rupture. Despite a thorough analysis of the removed catheter, the definitive cause of rupture could not be determined. Chronic mechanical stress, exacerbated by obesity (body mass index 40.74 kg/m2), was thought to induce catheter rupture. Additionally, the peritoneal wall anchor technique may be associated with mechanical stress. Patients with obesity and ADPKD are at a high risk of catheter rupture. Therefore, intraperitoneal catheter rupture should be considered a differential diagnosis when investigating the cause of poor drainage in patients undergoing peritoneal dialysis.
