Summary of the Annual Meeting of the Section on Urology, American Academy of Pediatrics

David R. Roth MD1

1 From the Scott Department of Urology, Texas Children's Hospital, Houston

The Section on Urology of the American Academy of Pediatrics met for 2frac12 days in conjunction with the 61st annual meeting of the American Academy of Pediatrics in San Francisco, CA, October 10 through 12, 1992.

As in the recent past, this conference was one of the premiere conferences for pediatric urology throughout the world. Participation was international and more than 500 individuals attended the sessions. The presiding officer for the meeting was Dr Edmond Gonzales, Jr, of Baylor College of Medicine, Scott Department of Urology, Houston, TX. All papers presented at the meeting are summarized in the following review, which is organized according to topic.

TESTIS

Several papers were presented by the group led by Hutson from Melbourne concerning the relationship of various substances to the gubernaculum and testicular descent. Their presentations stressed the importance of calcitonin gene-related peptide as a mediator in testicular descent by its relationship to the gubernaculum. Huff described a failure of maturation of Ad spermatogonia in undescended testes when compared to their normally descended partners. These changes were noted before the end of the first year of life. Hadziselimovic and Bica from Basel and Rio de Janeiro investigated the effects of hormonal treatment on the undescended gonad. Low-dose luteinizing hormone-releasing hormone increased both serum follicle-stimulating hormone and the number of Sertoli cells in cryptorchid testes. Human chorionic gonadotropin administration, on the other hand, induced Sertoli cell damage, which was reversed by the addition of luteinizing hormone-releasing hormone. Choi et al from the Seoul National University Children's Hospital looked at the effects of testicular torsion and subsequent detorsion on the contralateral testicle in rats.
