Sonographic appearance of the uterus in the early puerperium in vaginal versus cesarean deliveries: a prospective study.
The purpose of this study is to compare uterine sonographic characteristics in early puerperium, following vaginal versus cesarean deliveries; and in women with abnormal third stage of labor, compared to uncomplicated vaginal delivery.MATERIALS AND METHODS
This is a prospective study of women after delivery of singleton, appropriate-for-gestational-age weight, term neonates; 66 women delivered vaginally and 33 delivered by cesarean section. Sonographic uterine dimensions (height, length, and width), intracavitary thickness and its echogenicity (at level of fundus, midcavity and cervix) were recorded at less than and after 24 h from delivery, and compared between women delivered vaginally and by cesarean section. Among women delivered vaginally, data were further analyzed according to whether women underwent manual revision of the uterine cavity.RESULTS
Sonographic evaluations were taken at 15.4 (4.3-24.0) and 39.5 (28.8-108.8) hours after delivery (median, range). We found no clinically significant differences in uterine characteristics according to mode of delivery or according to manual revision of the uterine cavity. The sonographic appearance of the uterus was similar when performed at less than or after 24 h from delivery.CONCLUSIONS
Postpartum sonographic evaluation of the uterus appears similar after vaginal and cesarean deliveries.
