Spontaneous Pregnancy After the Removal of Long-Term Retained Laminaria

We report the case of a woman with laminaria retention up to six years, followed by spontaneous pregnancy after the removal by hysteroscope of the intrauterine retained laminaria. A 26-year-old woman (G1P0) visited our hospital with complaints of prolonged menstrual bleeding, dyspareunia, and infertility. She had a history of dilatation and evacuation (D&E) at nine weeks of gestation six years earlier. A transvaginal ultrasound showed an artifact, and hysteroscopy revealed a long foreign body, which was suspected to be a laminaria retained after the prior abortion. In the hysteroscopic surgical procedure, the laminaria was cut, and the two halves were excised using resectoscope electrodes and hooked to the electrodes for removal. Thereafter, a year later, she conceived spontaneously and gave birth to a baby by cesarean delivery due to the arrest of labor progress. We are the first to present a pregnant case after the removal of a six-year retained laminaria.
