[Use of the urocytogram in sexual ambiguities before puberty]

The cellular material studied in the urinary sediment mainly obtained from exfoliated cells of the bladder trigone was submitted to hormonal stimulation. The urocytogram has proved a useful and even necessary examination to establish the hormonal check-up of a child suffering from early puberty. This simple, painless method, without any psychological consequences is also indicated in pediatric gynecology, and in certain sexual ambiguity cases. This examination, undergone by a child premature or not, contributes to the early diagnosis of congenital adrenal hyperplasia. In the course of childhood, it helps to investigate pseudohermaphroditisms and various malformations. This examination has proved an important help in the diagnosis of all the cases of sexual ambiguity.
