Women will have the initial slow-release Dinoprostone pessary removed followed by insertion of 1-5 Osmotic cervical rods (Dilapan-S® Aquacryl hydrogel rod; HPSRx Enterprises, USA) by a senior obstetrician or a midwife into the cervical canal, immediately after removal of the slow-release pessary using a vaginal speculum and a holder. The rods will be left for 12-24 hours.
