title: [Efficacy of transurethral resection of ejaculatory duct for treatment of ejaculatory duct obstruction: report of 60 cases].
abstract: OBJECTIVE
  To evaluate the effect of transurethral resection of ejaculatory duct (TURED) for treatment of ejaculatory duct obstruction (EDO).
  
  
  METHODS
  The clinical data of 60 cases of EDO from Oct. 2004 to Oct. 2010 were analyzed. The diagnostic criteria included semen analyses, fructose in seminal plasma, transrectal ultrasonography (TRUS), and vasography if necessary. All the patients were treated by TURED. Post-operative semen assay, postoperative patency rate and postoperative impregnation rate were followed.
  
  
  RESULTS
  Semen analyses in the majority of cases showed the typical characteristics of EDO, azoospermia, low semen volume (average 1.10 ± 0.76 mL), low pH (average 6.5 ± 1.4), absent or low semen fructose (average 5.86 ± 2.19 μmol/one ejaculation). TRUS showed pure dilation of both ejaculatory ducts in 15 cases, prostatic cyst in 6, pure dilated seminal vesicles on both sides in 10, unilateral dilated seminal vesicle in 4, dilation of both ejaculatory duct and seminal vesicles in 10, dilated seminal vesicles with prostatic cyst in 5, unilateral dilated seminal vesicle and contralateral aplasia of seminal vesicle in 2, dilated seminal vesicles with dilation and calcifications of both ejaculatory ducts in 3. The remaining 5 had unilateral dilated ejaculatory duct and seminal vesicle with contralateral aplasia of seminal vesicle. In all the cases followed up more than 6 to 78 months after TURED, 51 patients (85.0%) had improved semen parameters and 16 patients' wives (26.7%) had pregnancies.
  
  
  CONCLUSIONS
  TURED may be the simple, minimally invasive and effective method for the treatment of EDO.
