[Urocytogram and precocious puberty].

After a review of the technique of urocytogram the authors report the results obtained in 39 children between the ages of 3 and 12 years. Before the appearance of the first signs of puberty, urocytograms are similar in both girls and boys. Differences were seen in seven cases of male or female precocious puberty. Urocytograms are also different in patients with incomplete precocious puberty but less marked than in those with true precocious puberty. The authors consider the possibility of repeat urocytograms during the supervision or treatment of incomplete and complete precocious puberty.
