[Application of vasoseminal vesiculography to the diagnosis of seminal ductal system disorders].

Vasoseminal vesiculography is becoming more and more valuable to the diagnosis of seminal ductal system diseases. Vasography can be performed by either trans-scrotal injection into the vas deferens, or transperineal injection into seminal vesicle, or retrograde insertion of a catheter into the opening of the ejaculatory duct. A good knowledge of the indications and proper judgement of the X-ray signs may significantly improve the diagnosis and treatment of the diseases of the seminal vesicle and ductal system.
