Testicular teratoma with nephroblastoma component.

We report the development of Wilms' tumor in an atrophic testis and review the potential molecular pathogenesis. An 18-year-old man presented with 2 days of right testicular pain and growth in his atrophic testis. Ultrasonography revealed a heterogeneous mass.

Nonoperative management of a patent urachus.

Patent urachus accounts for 10% to 15% of all reported urachal abnormalities in the literature. Treatment in the past has relied on immediate surgery. Conservative therapy with bladder catheter drainage, resulting in spontaneous closure, has not been described.

The role of radical prostatectomy in patients with pretreatment prostate-specific antigen > or = 40 ng/mL.

Objective: To assess the efficacy of radical prostatectomy (RP) in men presenting with markedly elevated prostate-specific antigen (PSA) levels, the records of 17 patients presenting with serum PSA values > or = 40 ng/mL, who underwent RP at Walter Reed Army Medical Center (WRAMC) between 1990 and 1995, were reviewed.

Methods: Pathologic and clinical data (staging, Gleason score, recurrences, adjuvant and neo-adjuvant treatment, most recent PSA value, urinary continence, and sexual function) for each patient was examined. The Kaplan-Meier method was used to analyze the disease-free survival (DFS) for PSA and clinical recurrence.
