Preterm Labour Clinic

The Preterm Labour Clinic commenced at Saint Mary's in 2000. Our aim is to improve the treatment of women who are at risk of a spontaneous preterm delivery. Women are managed between 16-28 weeks of pregnancy by a specialist midwife and a consultant obstetrician who are based in the Clinical Research Area.

Women usually receive an ultrasound scan of their cervix at every visit and the frequency of visits is flexible depending upon patient need. Our aim is to get the best possible outcome for women and babies by using the most up-to-date techniques and treatments available. The clinic also takes part in research, with patients sometimes being asked to take part in studies when they come for their clinic appointments.



Clinics are held in the Clinical Research Suite, 5th Floor, Saint Mary's Hospital on Thursday mornings.


The criteria for referral to this specialist clinic are:

  • Previous spontaneous premature labour and delivery before 32 weeks gestation.
  • Previous premature pre-labour rupture of the membranes before 32 weeks gestation.
  • Previous 2nd trimester loss over 16 weeks' gestation. This excludes 'haemorrhagic miscarriage', missed abortion etc.
  • Confirmed uterine abnormality eg, bicornuate uterus.
  • Previous cervical surgery - knife cone biopsy, patients who have had 2 or more LLETZ procedures.

Our staff include:
