Technical refinement of seminal vesiculoscopy and clinical application in seminal vesicle disease / 中华泌尿外科杂志

ABSTRACT

Objective To refine the technique and improve the efficacy of seminal vesiculoscopy in the diagnosis and treatment of seminal vesicle disease.Methods The refined techniques of seminal vesculoscopy,using a patent catheter into the slit-like ejaculatory duct orifice through the verumontanum and another patent catheter introduced into seminal vesicle lumen,were performed in 58 cases,including intractable hematospermia in 42 cases and azoospermia in 16 cases.Results Seminal vesiculoscopy was successfully entered into the seminal vesicular lumen in 46 patients (79％) within 2-3 min.There was no obvious ejaculatory duct orifice in 12 of 16 azoopermia cases,and transurethral resection of verumontanum was performed,then seminal vesiculoscope was directly entered into seminal vesicle lumen.Symptoms of hematospermia were disappeared in 25 cases (60％),improved in 11 cases (26％),and azoospermia were cured in 6 cases (37％),improved in 5 (31％),unchanged in 5 (31％) during the follow-up period of 6-36 months (average 18 months).There were no major or minor complications in this series,and no urine reflux into ejaculatory duct in 19 cases demonstrated by contrast medium.Conclusion Refined seminal vesiculoscopy was technically safe,efficient,simple,and potentially widely used in the cases of hematospermia and ejaculatory duct obstructions.
