ureter

Endometriosis is a chronic condition defined by the presence of endometrial-like tissue outside of the uterus, which can lead to estrogen-driven inflammation. The extent of disease can be highly variable, ranging from minimal peritoneal deposits to deep disease that can invade into the bowel, bladder and ureter and, more rarely, spread to extrapelvic (e.g., cutaneous, thoracic) sites. Endometriosis is a complex disease that has considerable impact on the quality of life of those affected and that has no cure. It remains poorly understood. We review the epidemiology, pathophysiology, diagnosis and management of endometriosis, based on the best available evidence and clinical guidelines
