Internal Endometriosis
Conditions
Brief summary
To describe Gonadotropin-Releasing Hormone agonists (GnRH-a) treatment effectiveness on reduction of internal genital endometriosis symptom - menorrhagia - in different disease stages I, II, III in the Russian patient population scheduled for treatment with Diphereline 3,75 mg - assessment performed six months after the last injection.
Interventions
This is a non-interventional (observational) national multicentre prospective study. Treatment was administered according to the Summary of Product Characteristics (SmPC): maximum 6 injections administered every 28 days. The decision to prescribe GnRH-a (Diphereline 3,75 mg) was made prior to and independently from the decision to enroll the patient into the study.
