腹膜透析是利用腹膜从终末期肾病患者的体液中转运出代谢废物和多余水的透析方式,是治疗终末期肾病的肾功能替代疗法之一。随着技术的不断进步以及新型腹透液的不断涌现,持续性非卧床腹膜透析(continuous ambulatory peritoneal dialysis,CAPD)逐渐在世界范围内广泛应用。腹膜腔置管及腹透液在腹腔的存留可能引起诸多并发症,而并发症可限制其长期应用甚至中止CAPD。因此,早期发现并及时控制并发症的发展对CAPD继续治疗尤为重要。影像学检查在早期发现、诊断腹膜透析相关并发症及指导临床制定治疗方案中有重要意义,合理的影像学检查能够显著地提高生存率, Peritoneal dialysis is the use of peritoneal fluid from patients with end-stage renal disease in the transport of metabolic waste and excess water dialysis is one of the treatment of end-stage renal disease, renal function replacement therapy. As technology continues to evolve and new peritoneal dialysates continue to emerge, continuous ambulatory peritoneal dialysis (CAPD) is gradually becoming more widely available worldwide. Peritoneal catheterization and peritoneal fluid retention in the abdominal cavity may cause a lot of complications, and complications can limit its long-term use or even stop CAPD. Therefore, the early detection and timely control of the development of complications is particularly important for continued treatment of CAPD. Imaging examination in the early detection and diagnosis of peritoneal dialysis-related complications and guide the clinical development of treatment programs are of great significance, a reasonable imaging examination can significantly improve the survival rate,
