Abstract

Abstract:

The embryonic intermediate mesoderm and cloaca derive a functional stratum which contains kidney, ureter, reproductive blood vessels and continues to bladder, vas deferens, seminal vesicle and prostate. We name this stratum as ″urogenital stratum (UGS)″, the surface of urogenital stratum is urogenital fascia (UGF). The rectum is surrounded by urogenital stratum, the peri-rectum fascia is visceral layer of urogenital fascia and the peri-rectum space is between fascia propria of rectum and visceral layer of urogenital fascia. The posterior dissection plane of TME is in presacral space and dorsal part of UGS is resected. The anterior dissection plane of TME is in peri-rectum space to preserve visceral layer of UGF so as to pretect inferior hypogastric plexus and its brunch. The plane of TME crosses the UGS and meet at the lateral structure of rectum.

Key words: Rectum, Intermediate mesoderm, Urogenital stratum, Peri-rectal fascia
