The Section of Urology of the American Academy of Pediatrics met for three days in conjunction with the 54th annual meeting of the Academy in San Antonio. Papers of interest to the pediatrician are summarized herein according to topic. The number of basic research papers is continuing to increase. The second annual Pediatric Urology Medal was awarded to Sir David Innes Williams for contributions made to the field. ANDROLOGY Testicular Torsion Some recent studies suggest that individuals who undergo testicular torsion may have a higher incidence of infertility than the normal male population.1,2 A number of papers were presented at the 1984 meeting debating a possible immune response that is initiated by the torsed testicle and that plays havoc on the nontorsed testicle. One such paper presented this year by Howards and Turner could not find any contralateral testicular damage following surgically induced torsion on rats. Hadziselimoyic and co-authors studied biopsies taken from the nontorsed testicle in 38 boys who underwent surgery for unilateral testicular torsion. In 20 of the 38 patients (58%), preexisting contralateral testicular abnormalities could be identified, which suggests that the infertility in patients with unilateral testicular torsion may be a consequence of preexisting testicular pathology rather than an immunopathy. Cryptorchidism Contralateral Testicle. Three studies addressed the problem of infertility in patients with a history of cryptorchidism and the effect of the undescended testicle upon the contralateral testicle. In one study, Kogan and associates set out to determine whether surgically induced cryptorchidism produces a deleterious effect upon the normally descended contralateral testicle.

The Section of Urology of the American Academy of Pediatrics met for three days in conjunction with the 53rd annual meeting of the Academy in Chicago. Papers and panel discussions that would be of interest to the pediatrician are summarized herein according to topic. As there has been an increasing number of basic research papers presented in recent years, the Section, this year, initiated a prize for basic research. Also new to the meeting was the awarding of the first annual Pediatric Urology Medal, which was given to Harry Spence for contributions made to the field. TESTICULAR TORSION Recent reports of unilateral testicular torsion have suggested that adverse effects may occur to the contralateral testicle, if the ischemic testicle is treated by surgical detorsion and left in place rather than removed.1-4 Three authors addressed this problem by investigating animal models. Animal Models In prepubertal rats undergoing experimentally produced testicular torsion, Rabinowitz and associates found histologic changes in the contralateral testicle. The changes in the contralateral testicle were dependent upon the duration of torsion and were significantly greater when the ischemic testicle was detorsed and left in place. The degree of histologic changes in the ischemic testicle, especially the degree of germ cell damage, was the best prediction of long-term damage to the contralateral testicle. In the animal model, these changes could be averted by removing the ischemic testicle. Although not going as far to recommend orchiectomy as the treatment of choice for all cases of torsion, Dr. Rabinowitz did suggest that a testicular biopsy in prepubertal boys with testicular torsion may be a reliable index to subsequent long-term contralateral damage if the ischemic testicle is detorsed and pexed rather than removed.

The Section on Urology of the American Academy of Pediatrics met for three days in conjunction with the 55th Annual Meeting of the Academy n Washington, DC. Papers of interest to the pediatrician are summarized herein according to topic. The number of basic research papers is continuing to increase, and this in no small part is due to the encouraging influence of the recipient of this year's Pediatric Urology Medal, F. Douglas Stephens. FETAL OBSTRUCTIVE UROPATHY The majority of cases of hydronephrosis diagnosed in the newborn are first detected prenatally by in utero ultrasound. It is important to realize that not all cases of renal pelvic distension represent obstruction. Of 100 cases of abnormal antenatal renal ultrasound, Ahmed and LeQuesare found that surgery was necessary in 48 infants. The remainder either had normal kidneys on imaging studies after birth or the dilation was insignificant or decreased with time. The most common abnormality seen was ureteropelvic junction obstruction. Schwarz and coauthors evaluated the efficacy of antenatal ultrasound in diagnosing hydronephrosis at various times during gestation and found a low sensitivity before 20 weeks and a high sensitivity between 35 and 40 weeks. They found that the fetal hydronephrotic kidney did well in utero, leading them to believe that most cases of hydronephrosis should not be tampered with but instead should be dealt with postnatally. Elder and coauthors reviewed the literature to determine whether in utero treatment of fetal obstructive uropathy has been effective. They found numerous instances of misdiagnosis and complications that included inadequate shunt drainage or migration (20%), onset of premature labor within 48 hours (10%), chorioamnionitis (6%), and urinary ascites (6%).

The Section on Urology of the American Academy of Pediatrics met for 3 days in conjunction with the 56th Annual Meeting of the Academy in New Orleans, Louisiana. Throughout the meeting, numerous research papers were presented along with clinical reports. This meeting has become the premier pediatric urology meeting and attracts worldwide attendance and participation. The growth of clinical and research aspects of pediatric urology has long been promoted by the recipient of this year's Pediatric Urology Medal, John K. Lattimer. URETEROPELVIC JUNCTION OBSTRUCTION The problem of neonatal ureteropelvic junction obstruction, its evaluation, and the criteria for intervention are areas of intense interest to both the pediatric urologist and the primary care pediatrician.
