Abstract A retrospective investigation into the prevalence of stress incontinence in women delivered by elective cesarian section (without experience of labor) in Lund from 1974 to 1979, was carried out in 1980. Of 264 women whose replies were solicited, 204 responded. The others had moved about and could not be reached. Permanent stress incontinence was reported by a significant number of patients without experience of labor. This supports our earlier findings which indicated that pregnancy and hereditary factors are more decisive in bringing about stress incontinence than the delivery itself.
