Methods: In 131 cases of adenoma of the posteriorurethra, aged 17-79 (mean: 36.4) years, a detailed medical history was taken and urinalysis, urethroscopy, and pro-static specific antigen (PSA) immunohistochemical staining were performed. They were then treated with transurethralresection (TUR) or transurethral electric coagulation (TUEC). Results: Hemospennia occurred in 51% of the cas-es, hemamria in 38%, blood overflow from the urethral orifice in 6%, and dysuria in 5%. The position of the tumorwas at or around the vemmontanum. The appearance of the tumor was similar to those of a papilla, a villus, a dactylor polyp, or simply an engorgement. The tumor contained glandular alveoli and adeno-epithelial cells. PSA immuno-histochemistry was positive in the cytoplasm and nucleus of the adeno-epithelial cell. One hundred and tweenty-ninecases were cured after TUR or TUEC, while 2 patients recurred and were operated again. Conclusion: Adenoma ofthe posterior urethra is a common cause of hemospennia and hematuria in young men. Urethroscopic examination andbiopsy are the principal diagnostic measures. TUR or TUEC are believed to be the treatment of choice with a short-termrecurrence rate of around 1.5%. (Asian J Androl 2000; 3: 67-70)展开更多
