Management of a high-risk pregnanacy with a severe form of bladder infiltrating endometriosis. Case report and literature review

Endometriosis is a gynecological estrogen-dependent disease, characterized by the presence of active endometrial tissue, represented by glandular epithelial and stromal cells, outside the uterine cavity. There have been described three types of endometriosis: peritoneal superficial endometriosis, ovarian endometriomas, and deep infiltrating endometriosis (DIE). DIE is deffined from a histologically perspective as a lesion that extends more than 5 mm into the peritoneal space or which affects the wall of the pelvic organs. Endometriosis of the bladder is considered to be a form of deeply infiltrating endometriosis. The relation with infertility involves multiple and complex mechanisms. It is estimated that over half of the patients affected by this condition are subfertile. Many women with either minimal, mild or severe endometriosis experience difficulties in conceiving or maintaining a pregnancy. We report the case of a women diagnosed with a severe form of infiltrating endometriosis, with endometrioma in the bladder, who obtained a pregnancy and delivered in the 39 week of gestation by caesarean section and had a good evolution.
