Ovaries are detached from the uterus along with its blood supply and transposed in an area away from the radiation field, generally in the para-colic gutters abovethe pelvic brim. Drawbacks of Ovarian Transposition:- 25% risk of benign ovarian cysts. 25% risk of benign ovarian cysts. 50% ovarian failure. 50% ovarian failure.

radical trachelectomy for cervical cancer 21www.zohrehyousefi.com
The formal name of this operation is radical vaginal trachelectomy (RVT) and also known as the Dargent operation and radical trachelectomy. 22www.zohrehyousefi.com
Trachelectomies, broadly, can be divided into the simple and radical variants. 23www.zohrehyousefi.com
A simple trachelectomy refers to the removal of the cervix; this can be considered to be a very large conization procedure conization 24www.zohrehyousefi.com

Summary Trachelectomy represents conservative surgical approach for early stage invasive cervical cancer Likely to increase in popularity Cytology is mainstay of follow-up Essentially cytological features are predictable and similar to those after cone biopsy 38www.zohrehyousefi.com
