Seminal vesicle tumor is a rare disease with unclear origin. Generally, it is presented as a pelvic mass that can be detected by sonography and digital rectal exam. The authors report a 25-year-old patient with a pelvic mass which the magnetic resonance and surgical specimen reveal a seminal vesicle tumor. Immunohistochemical findings favored a primitive neuroectodermal tumor of the seminal ves...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been shown to alter male reproductive development of laboratory animals through in utero and lactational exposure. As a result of exposure, the accessory glands of the male reproductive tract, including the seminal vesicle, are decreased in size as determined by total weight of the tissue. Analysis of seminal vesicle weights over time suggests that...

BACKGROUND Prostasomes are suggested to be produced in the prostate gland. Although biochemical studies support this, some immunohistochemical findings indicate that also the seminal vesicles could be a source of prostasomes. Therefore, we have compared the secretion of the vesicles with that of the prostate using biochemical and ultrastructural techniques. METHODS Ultracentrifuged pellets of...

vealed an absent right kidney, dilated right ureter and seminal vesicle, and a normal left renal tract (Figure 1). T1 and T2-weighted MRI with gadolinium again demonstrated right renal agenesis, a dilated, non-obstructed right ureter containing proteinaceous material with no vesical connection, and a dilated right seminal vesicle (Figures 2 and 3). Cystic dilatation of the right seminal vesicle...

Leiomyomas are common smooth muscle neoplasms; however, leiomyomas of the seminal vesicles are extremely rare. We report a case of seminal vesicle leiomyoma in a 55-year-old African American male who underwent robot assisted laparoscopic prostatectomy (RALP) for Gleason 8 (4 + 4) adenocarcinoma. An incidental nodule arising from the left seminal vesicle was discovered during surgery, complicati...

The removal of the seminal vesicle in 4-week-old, 6-week-old or 1.2-year-old rats resulted in a significant increase in the weight of the lateral prostate 6 weeks later examined. The weight change was mainly due to a marked distension of alveoli but showing close resemblance to structures of the control animals with secretory activity. RNA/ DNA ratio in the unit tissue increased. Constricted al...

Background: To compare transrectal ultrasonography (TRUS) and TRUS-guided seminal vesicle aspiration in the diagnosis of ejaculatory duct obstruction (EDO). comparing the findings of TRUS and TRUS-guided seminal vesicle (SV) aspiration. Materials and Methods: Design: A retrospective case-controlled study comparing the findings of TRUS and TRUS-guided seminal vesicle (SV) aspiration. Setting: Cl...

PURPOSE To investigate a new method and its effect on the procedure of dilating the ejaculatory duct and flushing the seminal vesicle with an F9 seminal vesicle scope in patients with chronic and recurrent seminal vesiculitis. PATIENTS AND METHODS Twenty-six patients with a diagnosis based to signs, laboratory detection, digital rectal examination, and transrectal ultrasonography were involve...

Abstract.-RNA prepared from the seminal vesicles of intact adult rats, or of testosterone-treated castrate adult rats, produced a 30 per cent increase in the weight of the seminal vesicle and a 25 per cent increase in the incorporation of labeled amino acids into protein. RNA prepared from the liver or ventral prostate of the same animals produced only a 10 per cent increase in the weight of th...
