During a 3-year period, 93 prenatal diagnoses of kidney or urinary tract abnormalities were carried out in the French district of Puy-de-Dôme. Sixty-nine mothers were resident in this area giving an incidence of 2.8 out of 1000 births. The pregnancy was interrupted in 10 cases, there were 2 stillbirths and three infants died within two months of life. The most frequent abnormalities were: hydronephrosis (48% of cases), megaureter with or without ureter duplication (19%) and multicystic dysplasia (16%). The prenatal diagnosis was confirmed after birth in 82% of cases. Of the 56 infants with obstructive uropathies, 17 underwent a pyeloplasty within three months of life, 32 had conservative treatment, of whom 4 were operated on afterwards, and seven could not be traced. Of the seven infants who had normal ultrasound scan at birth, three had abnormal scan during the follow-up one of whom was operated on. Nephrectomy was not performed in any of the 11 cases of multicystic dysplasia: one patient was lost to follow up, three had stable lesions and in seven cases, the size of the cysts decreased. |
