Sonographic diagnosis of complete uterine inversion: an unusual case.

Complete puerperal uterine inversion is an uncommon but potentially life-threatening obstetric emergency. It generally occurs as an obstetrical complication in the postpartum period and can present in acute, subacute, and chronic forms depending on the time interval after delivery. Maternal mortality has been reported to be as high as 15%, mainly because of life associated threatening blood loss and shock. Early diagnosis and treatment are essential, but diagnosis of this is not simple. This is a report of unusual case of complete uterine inversion diagnosed by accurate ultrasound leading to prompt potentially life-saving treatment.

Prognostic value of three-dimensional ultrasound for fetal hydronephrosis.

The present study evaluated the prognostic value of three-dimensional ultrasound for fetal hydronephrosis. Pregnant females with fetal hydronephrosis were enrolled and a novel three-dimensional ultrasound indicator, renal parenchymal volume/kidney volume, was introduced to predict the postnatal prognosis of fetal hydronephrosis in comparison with commonly used ultrasound indicators. All ultrasound indicators of fetal hydronephrosis could predict whether postnatal surgery was required for fetal hydronephrosis; however, the predictive performance of renal parenchymal volume/kidney volume measurements as an individual indicator was the highest. In conclusion, ultrasound is important in predicting whether postnatal surgery is required for fetal hydronephrosis, and the three-dimensional ultrasound indicator renal parenchymal volume/kidney volume has a high predictive performance. Furthermore, the majority of cases of fetal hydronephrosis spontaneously regress subsequent to birth, and the regression time is closely associated with ultrasound indicators.
