Prenatal hydronephrosis.

Hydronephrosis is the most common genitourinary tract anomaly identified on prenatal ultrasound studies. Ureteropelvic junction obstruction accounts for approximately 50% of the cases of prenatally detected hydronephrosis. Postnatal evaluation allows for the identification of the cause and further management. Rarely, in utero intervention may be performed for severe oligohydramnios associated with hydronephrosis. Prenatal consultation with a pediatric urologist is useful in decreasing parental anxiety and facilitating postnatal management.

To circ or not to circ: indications, risks, and alternatives to circumcision in the pediatric population with phimosis.

Summary Although there continues to be considerable debate over the merits of circumcision, it is clear that preservation of the pediatric foreskin, even in the presence of phimosis, is a viable option. Steroid topical cream is a painless, less-complicated, and more economical alternative to circumcision for treating phimosis. Success rates are quite high, especially when patient selection is appropriate and parents are adequately instructed on application. In those children in whom topical steroid therapy has failed, there remains a variety of foreskin-preserving surgical options for treating phimosis. Compared to circumcision, these less-invasive techniques are associated with lower morbidities and cost. Furthermore, depending on the tissue-preserving technique used, satisfactory cosmesis is also achieved. Thus, those males who were not circumcised at birth now have medical and surgical options, which will decrease the likelihood of requiring circumcision at an older age. As health care providers in the United States see more and more uncircumcised male children, it is important for these children and their parents to understand the natural history of physiologic phimosis. Additionally, it is the responsibility of health care providers to present the management options available for the treatment of the persistent nonretractile foreskin and/or pathologic phimosis. These options are particularly important for those individuals whose religious, cultural, or personal preference is to retain the foreskin.

Tolterodine treatment for children with symptoms of urinary urge incontinence suggestive of detrusor overactivity: results from 2 randomized, placebo controlled trials.

PURPOSE: We report the results of the first 2 large randomized controlled trials designed to evaluate the efficacy and safety of tolterodine extended release in children 5 to 10 years old with symptoms of urinary urge incontinence suggestive of detrusor overactivity. MATERIALS AND METHODS: Two double-blind, placebo controlled trials were conducted sequentially. Children 5 to 10 years old with incontinence suggestive of detrusor overactivity (1 or more diurnal incontinence episodes per 24 hours) were randomized to tolterodine (2 mg daily) or placebo for 12 weeks. The primary end point was the change from baseline to week 12 in the number of incontinence episodes per week. Changes from baseline in the number of voids per 24 hours and volume of urine per void were also evaluated. Exploratory analyses were conducted to determine whether particular subsets of patients showed differential responses to treatment. RESULTS: A total of 224 and 487 children (mean age 8 years) were randomized to placebo and tolterodine, respectively. Differences in the number of incontinence episodes per week, voids per 24 hours, and volume of urine per void between tolterodine and placebo did not reach statistical significance. This finding may be explained by a high placebo response and under dosage of tolterodine among children with greater body weight. Tolterodine was well tolerated. CONCLUSIONS: Analysis of the primary efficacy outcome did not reveal a statistically significant effect of treatment. However, secondary analyses demonstrated that tolterodine was well tolerated among 5 to 10-year-old children with diurnal incontinence. Exploratory analyses also showed that children weighing 35 kg or less with detrusor overactivity characterized by incontinence and/or frequent voiding benefited most from tolterodine treatment, suggesting that a weight adjusted dosing regimen may be required for optimal response among older and heavier children.
