Obstetrics & Gynaecology Overview

Established in 1986, the Department of Obstetrics & Gynaecology at SGH is a comprehensive clinical department that provides investigative, treatment and emergency services for a whole range of obstetric and gynaecological conditions.

Set within a general hospital setting and always in close collaboration with the specialty centres, our patient-centric model of care delivery has made us a referral centre for tertiary care of complex gynaecological conditions and high risk obstetrics cases.

Our multidisciplinary team of experienced clinicians and specialist nurses ensure that all our patients’ needs are addressed, providing our patients and their families with the support they need during their period of illness and recovery.

For the health professional, our department has established itself as a centre for clinical education, training and research.

Against a backdrop of rapid developments, our department strives to provide our patients with the best care by keeping abreast of the fast changing panorama of women’s health.

Gynaecological Oncology

The Gynaecological Oncology service offers diagnosis and treatment cancerous and pre-cancerous conditions. The spectrum of surgery offered includes minimally invasive and robotic, open and major exenterative techniques collaborating in a multidisciplinary setting with other oncology specialties. Our own Clinical Nurse Specialist offers support to all women with suspected gynaecological malignancy throughout their time in the Unit.

Cervical screening and colposcopy assessment and treatment of cervical abnormalities are all offered including the recent introduction of HPV testing to aid optimum management

Maternal-Fetal Medicine

The MF section comprises a multidisciplinary team of doctors focusing on high-risk obstetrics and includes joint clinics with the endocrinologists and cardiologists.  The patient receives comprehensive care throughout pregnancy with labour being managed by the same team, led by a labour ward Lead Clinician.

First Trimester Screening for Down’s syndrome is performed by an experienced team of sonographers  accredited by the Fetal Medicine Foundation (United Kingdom).  Level II fetal anomaly scans are carried out in conjunction with prenatal invasive testing. There is also a one-stop scan clinic for monitoring multiple pregnancies.

Minimally Invasive & Robotic surgery

The Minimally Invasive and Robotic Surgery service was established in 2013 to provide state-of-the-art surgical techniques for all classes of patients and for a multitude of benign gynaecological conditions. It aims to offer MIS surgery for complex benign pathology where open surgery would generally be offered.

Minimally Invasive Surgery offers patients a shorter hospital stay, less post-operative pain, faster return to normal activities and improved cosmetic results. Robotics offers further enhancements to this by offering the surgeon the best operative view, most precise instruments and most ergonomic approach to keyhole surgery.

Reproductive Medicine

The Centre for Assisted Reproduction or CARE was established in 1987 to look after patients with both male and female with fertility problems. Our team of experienced IVF accredited specialists, nurses, embryologists and sonographers work together to offer state-of-the-art medicine in patients’ fertility and IVF journey. Individualised treatment is tailored according to the couple’s medical conditions and needs. Counselling services are also available as part of the holistic approach to patient care.

Fertility preservation for semen, oocytes, embryo and ovarian tissue storage services are also available for patients about to embark on treatment that may affect their fertility potential (e.g.: cancer patients going for chemotherapy).


Our urogynaecology section offers one-stop evaluation and treatment of women with urinary incontinence as well as pelvic floor dysfunction, including urogenital prolapse and post-hysterectomy vaginal vault prolapse. Our multidisciplinary clinic is a special service that looks after women with complex pelvic floor problems and is jointly run by our urogynaecologists, urologists and colorectal surgeons.

Depending on the nature of the urinary incontinence or pelvic floor dysfunction, therapeutic options including non-surgical management with the use of support devices such as pessaries for prolapse, pelvic floor training and medical therapy for bladder disorders. Surgical management may be considered in some women with severe symptoms or when conservative treatment is ineffective. 

Ultrasound Services

Ultrasound services is integral to O&G and our team of experienced sonographers provide a comprehensive service and perform more than 25 000 scans per year. Established in 1987, the team has expanded their service of performing ‘routine’ gynaecological scans to performing specialised scans in the Centre for Assisted Reproduction (CARE), Prenatal Diagnostic Centre (PDC) and the Early Pregnancy Unit (EPU). 

Established in 2006, the EPU facilitates prompt access for patients with first trimester complications and aims to centralise and streamline assessment, diagnosis, management & counselling of patients with conditions such as miscarriages and ectopic pregnancies.
