Purpose: Anorectal and urologic sequelae are observed in long-term survivors of sacrococcygeal teratoma (SCT). In this study we evaluate the incidence and predictors of anorectal and urologic complications in SCT.
Methods: A retrospective review was performed for all SCT patients who underwent resection at a single institution between 2000 and 2012.
Background And Objectives: Approximately 20% of boys with posterior urethral valves develop ESRD; however, few factors associated with the risk of ESRD have been identified. The objective of this study was to determine if renal parenchymal area, defined as the area of the kidney minus the area of the pelvicaliceal system on first postnatal ultrasound, is associated with the risk of ESRD in infants with posterior urethral valves.
Design, Setting, Participants, & Measurements: A retrospective cohort of boys who were diagnosed with posterior urethral valves at less than 6 months of age between 1988 and 2011 and followed for at least 1 year at a free-standing children's hospital was assembled.
Purpose: We hypothesized that active surveillance of the adolescent varicocele is not associated with a high prevalence of suboptimal semen analysis and that patients with abnormal semen analysis have smaller testicular volumes and larger volume differentials.
Materials And Methods: We conducted an institutional review board approved retrospective cohort study of adolescents with a clinically detected varicocele. Patients were initially observed by serial scrotal ultrasound evaluating testicular size and differential.
