There is no validated tool in quality-of-life assessment of women with endometriosis in Croatia. First aim is to validate Endometriosis Health Profile-5 (EHP-5) before implementing this questionnaire in clinical practice. After validation, we will prospectively follow women with endometriosis through whole process - pre- and postoperatively.

There is no validated tool in quality-of-life assessment of women with endometriosis in Croatia. First aim is to validate Endometriosis Health Profile-5 (EHP-5) before implementing this questionnaire in clinical practice. After validation, we will prospectively follow women with endometriosis through whole process - pre- and postoperatively, including comparison with rASRM and Enzian score which are already established in our Clinic.

We will try to identify correlation between EHP-5 score and surgical findings and to provide better insight in quality of life consideration of women with endometriosis particularly in Croatia. Since we are tertiary referral centre with almost 250 operative procedures which include ovarian, pelvic and/or extra pelvic endometriosis, we believe that this study will bring new tool not only for preoperative assessment but postoperative surveillance.

Inclusion Criteria:

• aged between 18 and 50 years; symptoms of endometriosis (pelvic pain, dyspareunia, dysmenorrhea) for at least 6 months or previously verified primary sterility; pathohistological confirmation of diagnosis after surgical treatment or indicated diagnostic laparoscopy; fluent and literate in Croatian language; ability to independently understand the questions in the questionnaires

Exclusion Criteria:

• pregnant women; cognitive impairment or intellectual disability; neurological disorders (e.g. epilepsy, Parkinson disease, multiple sclerosis, cerebrovascular insult); lack of independent mobility and polytraumatic patients; diagnosed vulvodynia and active vulvovaginitis; ongoing urinary tract infection; any form of prior conservative and/or surgical treatment for endometriosis; lack of informed consent

We will include at least 100 women with surgically proven endometriosis in order to establish EHP-5 in our clinical practice.
