Anatomy Of The Perirenal Space And Renal Fascia: Study With Multi-slice Spiral CT In Vivo

Objective: To describe the anatomy of the superior and inferior aspect of the perirenal space as well as the renal fascia with CT radiography in vivo. Materials and Methods: 97 healthy people and 24 patients with pancreatitis were adopted in this experiment. All images were obtained with Siemens sensation 16 scanner(collimation width=0.75mm, table increment=7mm/s, scan delay time=25-50s, reconstruction interval=7mm) and the relevant images of 3-D reconstruction were made. Results: 1) Thickness of renal fascia was 0.13 ± 0.02cm on the left and 0.12 ± 0.02cm on the right respectively; 2 ) It was easier to see the renal fascia on sagittal CT images than that on transverse CT images; 3) The anterior and posterior renal fascia were fused laterally behind the kidney in 14 cases (11 on the left and 3 on the right); 4)Superiorly, the renal fascial layers were fixed in 85 cases on the left , while the fixation were not found in 12 cases on the left and all the cases on the right; 5) Inferiorly, the fusion of the two fascial layers were observed in 95 cases bilaterally, and the two layers were fused partially in the remaining two cases on both sides; 6) In the group of patients with pancreatitis, the left fascial layers...
