Removal of Intrauterine Retained Products of Conception (RPOC) After Miscarriage Guided by Hysteroscopy Trial. A Randomized Controlled Trial.

Design : RCT * Multicenter * Randomized controlled * Parallel group design * Superiority trial * Non-blinded Primary Objective To compare the effectiveness in terms of time to next pregnancy between operative hysteroscopy and expectant management in patients with sonographic evidence of RPOC after primary non-surgical management of miscarriage. Secondary Objectives 1. Effectiveness objectives To compare the effectiveness between operative hysteroscopy and expectant management with respect to: * Generic quality of life (QOL) (as measured by SF-36, HADS (Hospital Anxiety and Depression Scale)) and EQ-5D-5L 6 months after randomization * Course of pregnancy in those women who have an ongoing pregnancy after randomization during the study follow-up period (including miscarriage, ectopic pregnancy and live birth) 2. Safety objectives To compare the safety between operative hysteroscopy and expectant management with respect to: * Necessity for additional treatment * Out-of-protocol/unscheduled visits to the outpatient clinic or general practitioner * Complications 3. Cost-effectiveness objectives To compare the health related costs between operative hysteroscopy and expectant management.
