Associate Professor George Condous



George Condous is consultant gynaecologist at Nepean Hospital in West Sydney. He is Associate Professor in Obstetrics and Gynaecology and Nepean Head of Discipline at Nepean Clinical School, University of Sydney. He runs the Acute Gynaecology Service which sees women with emergency gynaecological as well as early pregnancy complications (miscarriage and ectopic pregnancy). He is also responsible for the One-Stop Ultrasound based diagnostic clinics; which review women with abnormal uterine bleeding, chronic pelvic pain, adnexal pathology as well as post-menopausal bleeding. He is also performs Advanced Endosurgery procedures for women who need intervention for pelvic masses, frozen pelvis, endometriosis or hysterectomy.

Having completed his undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 – 2003 he worked as a Senior Research Fellow to Tom Bourne at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom, which used ultrasound at the point of the initial consultation to evaluate women with gynaecological problems. It was also during this position that he developed his great interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). He has developed many mathematical models for the prediction of outcome of PULs which have featured in peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the world recognised Centre for Advanced Reproductive Endosurgery, Sydney.
He was appointed as a consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005.

He has edited one book entitled the Handbook of Early Pregnancy Care, published over 50 papers in international journals and is internationally renowned for his work in early pregnancy. He is the Associate Editor for Gynecologic Obstetric Investigation, which is a European based journal, as well as on the organising committee for this year’s Australian Gynaecological Endoscopy Society (AGES) meeting in Sydney. His current research interests relate to the management of ectopic pregnancy, PULs and miscarriage, as well as the use of sonovaginography to predict rectovaginal endometriosis.

Professor Ron Benzie

ron benzie


Professor Ron Benzie’s main research interests for the past years have been in the field of prenatal diagnosis. He founded the international fetal anomaly database PLATYPUS (Programme Listing Abnormality and Prenatal Ultrasound) and is involved in the development of electronic aids to diagnosis and the assessment of their role in medical education. His current research is concerned with prenatal fetal diagnosis using 3D and 4D ultrasound technology.
