作者将有腹膜后液体盆腔扩散的病人分为4组:①液体来自前肾旁间隙(17例),诊断包括胰腺炎(10例)、胰腺损伤(2例)、胰十二指肠切除后的漏出液(1例)、阑尾炎(1例)和结肠脓肿(3例)。②液体来自肾周间隙(16例),诊断包括肾感染(4例)、肾损伤(5例)。肾尿瘤(3例)、肿瘤出血(1例)、肾上腺肿瘤栓塞后水肿(1例)、腹主动脉瘤破裂(1例)。③来自肾旁后间隙的液体(1例)诊断为脊柱手术后出血。④隐源性(3例),诊断为食管胃静脉曲张,内镜硬化治疗后(1例),出血倾向(1例),不明原因(1例)。于腰_5椎体水平作CT扫描时,肾下腹膜外间隙横截面积可分为4级:无液体为0级;腹膜外间隙 The authors divided the patients with pelvic peritonoral fluid diffusion into four groups: ① fluid from the anterior para-renal space (17 cases) diagnosed including pancreatitis (10 cases), pancreatic injury (2 cases), pancreatoduodenectomy (1 case), appendicitis (1 case) and colon abscess (3 cases). ② fluid from the perirenal space (16 cases), diagnosis, including kidney infection (4 cases), renal injury (5 cases). (3 cases), tumor hemorrhage (1 case), adrenal tumor edema after embolization (1 case) and abdominal aortic aneurysm rupture (1 case). ③ Fluid from the posterior renal access space (1 case) was diagnosed as bleeding after spinal surgery. ④ cryptogenic (3 cases), diagnosis of esophagogastric varices, after endoscopic sclerotherapy (1 case), bleeding tendency (1 case), unknown reason (1 case). In the lumbar vertebral level for CT scan, the peritoneal extracorporeal cross-sectional area can be divided into four levels: no liquid level 0; extraperitoneal space
