This study gives the results of a year in which the active conduct of a trial of labour was carried out on uteruses that had scars in them. This approach allowed 22% of women to deliver vaginally out of a total of 41 patients. Of 17 patients (41.4%) that were put down for a tentative trial delivery, 9 (53%) did deliver vaginally. This approach seems to have been reasonable and beneficial so long as proper precautions were taken. The prognosis is better if there has been a previous vaginal delivery.
