The Gynaecological research team

The gynaecological team conduct research on a broad front focused on four main themes; ultrasound diagnostics, sexual and reproductive health, pelvic floor, robotic surgery and endometriosis.

The overall goal of the ultrasound research is to explore ultrasound as a diagnostic tool in the management of gynecological cancer as well as benign disease, in order to optimize utilization of healthcare resources and to avoid over and under-treatment. We evaluate new ultrasound techniques, conduct translational research, with the aim of tailor the treatment for each woman. We also develop and evaluate game-based learning and artificial intelligence in the diagnosis of ovarian tumours.

The sexual and reproductive health project includes:1/ Evaluation of home abortion up to 70 days gestation aiming to improve management of medical abortion, 2/ Reduce menstrual pain by exploring new treatment options for dysmenorrhea and endometriosis and evaluate quality of life for women affected by menstruation related pain. 3/ Explore potential adverse events during pregnancy and labour in women with a history of female genital mutilation.

Pelvic floor, robotic surgery and endometriosis: The aim is to 1/ Identify variables that could optimize outcomes in women who undergo surgical treatment for symptoms related to pelvic floor dysfunction. 2/ Find out if surgical more complex cases have less complications using robotic hysterectomy and apical prolapse as compared to other methods in Sweden. 3/ If ultrasound can predict severity of endometriosis in order to tailor surgery.
