Peritoneal scintigraphy, although rarely used, plays a vital role in the diagnosis of peritoneal dialysis catheter complications. Reported complications include spontaneous hydrothorax secondary to a pleuroperitoneal fistula, which requires the abandonment of peritoneal dialysis, given that a delay in diagnosis can lead to worsening clinical status. Previously reported peritoneal scintigraphy protocols recommended intraperitoneal instillation of radiotracer and moderate-to-large volumes of dialysate or sterile saline ranging from 350 to 2,000 mL. However, smaller volumes, in conjunction with the use of single-photon emission computed tomography/computed tomography, are not verified in patients receiving peritoneal scintigraphy imaging.
腹膜闪烁扫描术虽很少使用，但在腹膜透析导管并发症的诊断中起着至关重要的作用。报告的并发症包括继发于胸膜腹膜瘘的自发性胸腔积液，鉴于诊断延迟会导致临床状况恶化，这种情况需要停止腹膜透析。先前报道的腹膜闪烁扫描术方案建议腹腔内注入放射性示踪剂以及350至2000毫升的中到大剂量透析液或无菌盐水。然而，在接受腹膜闪烁扫描成像的患者中，较小剂量与单光子发射计算机断层扫描/计算机断层扫描联合使用的情况尚未得到验证。
