Adenoma of the posterior urethra: 131 case report

Aim: A case-report on adenoma of the posterior urethra. Methods: In 131 cas es of adenoma of the poste rior urethra, aged 17 - 79 (mean: 36.4) years, a detailed medical history was taken and urinalysis, urethroscopy, and prost atic specific antigen (PSA) immunohistochemical staining were performed. Th ey were then treated with transurethral resection (TUR) or transurethral el ectric coagulation (TUEC). Results: Hemospermia occurred in 51% of the case s, hematuria in 38%, blood overflow from thr urethral orifice in 6%, and dy suria in 5%. The position of the tumor was at or around the verumontanum. T he appearance of the tumor was similar to those Of a papilla, a villus, a d actyl or polyp, or simply an engorgement. The tumor contained glandular alv eoli and adeno-epithelial cells. PSA immunohistochemistry was positive in t he cytoplasm and nucleus of the adeno-epithelial cell. One hundred and twee nty-nine cases were cured after TUR or TUEC, while 2 patients recurred and were operated again. Conclusion: Adenoma of the posterior urethra is a comm on cause of hemospermia and hematuria in young men. Urethroscopic examinati on and biopsy are the principal diagnostic measures. TUR or TUEC are believ ed to be the treatment of choice with a short-term recurrence rate of aroun d 1.5%.
