Abstract

 

OBJECTIVE:

To observe the superior attachment of renal fascia RF and the perirenal space PS in order to identify the spreading pathway of inflammatory and malignant tumors.

METHODS:

Multidetector computed tomography MDCT, with double phase enhancement scanning and three dimensional reconstruction of images were performed on 121 healthy adults. The RF attachments upward were observed and their connections with the PS were evaluated.

RESULTS:

The left anterior renal fascia ARF fusing with peritoneum accounted for 27.3% 33/121 and the left ARF fusing with peritoneum of the spleen laterally and with the subdiaphragmatic fascia interiorly accounted for 19.8% 24/121 of the upper attachments of the RF above the upper renal pole URP. Under the URP, the left ARF fusing with peritoneum accounted for 52.9% 64/121 of the upper attachments of the RF. The right ARF fusing with peritoneum did not display above the URP. The posterior renal fascia PRF of both side fused with subdiaphragmatic fascia under the URP. The ARF and PRF of the left and right kidney showed no upward integration. The right PS communicated with the subdiaphragmatic retroperitoneal space SDRS that is a bare area of the liver. The left PS communicating with the SDRS accounted for 80.2% 97/121 and the left PS communicating with the SDRS laterally but separating from the SDRS interiorly accounted for 19.8% 24/121 of the SDRS communication.

CONCLUSION:

MDCT and three-dimensional reconstruction can remarkably display RF and its superiorattachment, as well as the connection between the PS and SDRS.
