OBJECTIVES: To describe the patients with gender identity disorder referred to a pediatric medical center. We identify changes in patients after creation of the multidisciplinary Gender Management Service by expanding the Disorders of Sex Development clinic to include transgender patients. METHODS: Data gathered on 97 consecutive patients <21 years, with initial visits between January 1998 and February 2010, who fulfilled the following criteria: long-standing cross-gender behaviors, provided letters from current mental health professional, and parental support. Main descriptive measures included gender, age, Tanner stage, history of gender identity development, and psychiatric comorbidity. RESULTS: Genotypic male:female ratio was 43:54 (0.8:1); there was a slight preponderance of female patients but not significant from 1:1. Age of presentation was 14.8 ± 3.4 years (mean ± SD) without sex difference (P = .11). Tanner stage at presentation was 4.1 ± 1.4 for genotypic female patients and 3.6 ± 1.5 for genotypic male patients (P = .02). Age at start of medical treatment was 15.6 ± 2.8 years. Forty-three patients (44.3%) presented with significant psychiatric history, including 20 reporting self-mutilation (20.6%) and suicide attempts (9.3%). CONCLUSIONS: After establishment of a multidisciplinary gender clinic, the gender identity disorder population increased fourfold. Complex clinical presentations required additional mental health support as the patient population grew. Mean age and Tanner Stage were too advanced for pubertal suppressive therapy to be an affordable option for most patients. Two-thirds of patients were started on cross-sex hormone therapy. Greater awareness of the benefit of early medical intervention is needed. Psychological and physical effects of pubertal suppression and/or cross-sex hormones in our patients require further investigation.
US methods of testicular volume measurement are more accurate and precise than orchidometry. The formula L x W x H x 0.71 provides a superior estimate of testicular volume and should be used in clinical practice.
Tubularized incised plate urethroplasty has become the preferred technique of primary and repeat hypospadias repair at our institution. The technique has few complications as well as proved success and versatility that continues to expand its applicability and popularity.
Studies in the streptozotocin rat model for diabetes mellitus suggest that sexual dysfunction in these animals may result from diabetes-induced alterations of the neuroendocrine-reproductive tract axis. Our investigation was performed to better define the effects of diabetes on the neuroendocrine sex accessory organ axis in the male rat. Rats were rendered diabetic, and were either left untreated or treated with insulin, testosterone or both. Diabetes resulted in decreased body and reproductive organ weights, as well as diminished sperm counts and motility and prostatic acid phosphatase. Seminal fructose was increased. A significant decrease in serum LH, FSH and testosterone was noted. Insulin treatment of the diabetic rats restored serum gonadotropins, reproductive organ weight, sperm counts and motility, and seminal fructose to control levels. Prostatic weight and prostatic acid phosphatase levels remained abnormal. Testosterone restored the above mentioned parameters to control levels, with the exception of LH. Treatment with insulin and testosterone had a synergistic effect on spermatogenesis. A GnRH stimulation test demonstrated that pituitaries of diabetic animals had a blunted response, with diminished LH and FSH secretion. In the diabetic animal, there are both pituitary and testicular abnormalities which may be responsible for reproductive dysfunction.
Our analyses demonstrate that resolution of vesicoureteral reflux is dependent on age at presentation, gender, grade, laterality, mode of clinical presentation and ureteral anatomy. We constructed nomogram tables containing estimates of annual reflux resolution rate as a function of these variables. This information is valuable for clinical counseling and management decisions.
Sonographically derived volume differentials greater than 10% between normal and affected testes correlate with a significantly decreased sperm concentration and total motile sperm count. This finding may serve as a marker to identify adolescents with unilateral left varicocele who are at greatest risk for future infertility. At least semen analysis and close annual followup of these adolescents seem warranted.
Robotic assisted laparoscopic ureteral reimplantation offers similar success rates to the gold standard, open ureteral reimplantation. Future large scale studies will be required to define further the costs and benefits of robotic assisted laparoscopic ureteral reimplantation in the surgical treatment of vesicoureteral reflux.
Objective To combine and analyse the results from centres with a large experience of laparoscopy for the impalpable testis with small series, to determine the expected success rate for laparoscopic orchidopexy. Methods A questionnaire was distributed to participating paediatric urologists; each contributor retrospectively reviewed the clinical charts for their cases of therapeutic laparoscopy for an impalpable testis, detailing 36 variables for each patient. The data were collated centrally into a computerized database. For inclusion, the testis was intra-abdominal (including 'peeping' at the internal ring) at laparoscopic examination, was not managed through an open approach and did not undergo orchidectomy. Three surgical groups were assessed, with success defined as lack of atrophy and intrascrotal position: group 1, primary laparoscopic orchidopexy; group 2, a onestage Fowler-Stephens (F-S) orchidopexy; and group 3, a two-stage F-S orchidopexy. Results Data were gathered from 10 centres in the USA, covering the period 1990-1999; 252 patients representing 310 testes were included and overall, 15.2% were lost to follow-up. There was no significant difference between success rates in the larger and smaller series. Atrophy occurred in 2.2% of 178 testes, 22.2% of 27 testes and 10.3% of 58 testes in groups 1-3, respectively. Testes were not in a satisfactory scrotal position in 0.6%, 7.4% and 1.7% of groups 1-3, respectively. The mean follow-up for each group was 7.7, 8.6 and 20.0 months, respectively. The overall success for all groups was 92.8% (97.2% group 1; 74.1% group 2; 87.9% group 3), with an atrophy rate of 6.1%. Conclusion Laparoscopic orchidopexy for the intraabdominal testis, in both large and small series, can be expected to have a success rate higher than that historically ascribed to open orchidopexy. Within this series, single-stage F-S laparoscopic orchidopexy resulted in a significantly higher atrophy rate than the two-stage repair. However, when considering both F-S approaches, the laparoscopic approach gave greater success than previously reported for the same open approaches. Despite the weaknesses inherent in a retrospective unrandomized study, we conclude that laparoscopic orchidopexy is, if not the procedure of choice, an acceptable and successful approach to the impalpable undescended testicle.
