In 30 cases (47%), 1-2 lymph vessels emerge from the uterine tubes and reach the pelvic wall through the broad ligament of uterus and terminate in the external iliac lymph nodes, internal iliac lymph nodes and common iliac lymph nodes.
Among 22 patients with lateral lymph node involvement, the rate of simple obturator and internal iliac lymph nodes metastasis is 54 5%; The rate of simple external iliac and common iliac lymph nodes metastasis is 18 1%.
the lymphatics emerging from the cervix uteri and the lower portion of the corpus uteri terminate in the external iliac nodes, the interiliac nodes, the internal iliac nodes, the paracervical nodes, the obturator nodes or the rectal nodes.
96 patients have been done high ligation of inferior mesenteric artery and abdominal aortic artery lymph node dissection(D3), transfer rate of inferior mesenteric artery lymph node (N3) was 11.5%, the difference of therapeutic effectiveness between the N3 transfer positive group and negative group were not obvious significance.
those of corpus uteri join in the sacrales lymph node; those of cervix uteri come together with the iliaci mediales lymph nodes and the sacrales lymph node. As many as 88.89% of the lymph vessels in the corpus uteri appear crossing in pigs, that is, 44.44% run from left to right ;
The results showed that the lymphatics of the bladder travelled in three routes: from the anterior wall of the bladder upward to the pelvic lymph nodes of the external, internal,common iliac and obturator arteries;
