Endometriosis is the benign, often painful growth of the uterine lining (endometrium) outside the uterus. Endometriosis may affect the ovaries, the fallopian tubes, the deeper layers of the uterus (adenomyosis) but also the urinary bladder, the ureters or the intestines. At the time of menstruation, cramp-like pain as well as chronic lower abdominal and back pain, pain during sexual intercourse, bowel movements or urination as well as infertility are typical symptoms of endometriosis. A prerequisite for the right treatment is the determination of the severity of the disease - which organs are affected and how? Extensive experience and modern ultrasound devices enable a quick, non-invasive diagnosis - but also the exclusion of a pronounced form of endometriosis. Whether and how endometriosis is treated is determined by its severity but also by a variety of accompanying circumstances.The goal is a personalized and effective therapy.
