[Maternal and perinatal data of hypospadic in a 25 year period].

OBJECTIVE

To analyze maternal and perinatal risk factors related to the onset and severity of hypospadias.

MATERIAL AND

METHODS

Data of 614 boys operated on hypospadias in our county during 25 years (1972-1998) has been studied. The patients were divided into 3 groups according the malformation severity: proximal, middle, and distal hypospadias. We use two periods, before and after 1980 to analyze the differences in risk factors along the time.

RESULTS

There were 9% of proximal hypospadias, 13.6% middle hypospadias, and 77.5% distal hypospadias. We found statistical significance in several risk factors related to severe hypospadias: low birth weight, intrauterine growth restriction, preterm births, and associated malformations (p < 0.001). We did not find statistical significance with maternal age, toxic exposure, associated diseases, and x-ray exposure during pregnancy. After 1980, there were more severe hypospadias and less gestational age.

CONCLUSIONS

Several events during pregnancy can contribute to the development of hypospadias in the fetus. In our experience, since 1980 there is a rise in the number and severity of hypospadias.
