To investigate the treatment of cystis vesicular seminalis induced by the obstruction of the distal end of the ejaculatory duct.
From November 2005 to December 2006,12 cases of cystis vesicular seminalis ([2.3 +/- 1.1] cm) were diagnosed by semen analysis (as on the seminal volume, pH and fructose), transrectal palpation and ultrasonography. All cases were treated by transurethral incision or resection of the obstructive ejaculatory duct till milky semen discharged.
The cysts were significantly reduced ([1.0 +/- 0.8] cm, P < 0.05) in all the 12 cases and no complications were observed during the follow-up 1, 3 and 12 months later.
Transurethral electrotomy is a simple and effective method for the treatment of cystis vesicular seminalis induced by the obstruction of the ejaculatory duct.
