Abstract
Transurethral bladder neck collagen injection therapy was performed in a patient with retrograde ejaculation. The phenomenon of retrograde ejaculation and its correction after the therapy were clearly demonstrated by color Doppler ultrasonography. To our knowledge this is the first report showing successful observation of retrograde ejaculation using color Doppler ultrasonography.
