Retrograde Ejaculation Due to Posterior Urethral Stricture: A Rare Case Report

Pelvic fracture is a serious injury, which has a profound impact on sexual function due to concurrent nervous and urethral injuries. In this case report, we describe a 29-year-old single man who had retrograde ejaculation as a result of a pelvic fracture-related posterior urethral stricture. The patient wanted to improve his ejaculatory ability after experiencing urethral stricture for 8 years and retrograde ejaculation for 3 years following the pelvic fracture. We precisely located and measured the patient's urethral stricture using a retrograde urethrogram, and we used transrectal color Doppler ultrasound to track the patient's ejaculation process in real time. Next, we used urethral balloon dilatation to relieve the urethral stricture. Urinary obstruction symptoms have completely resolved, and the patient was able to urinate without any obstructions. Meanwhile, the real-time transrectal color Doppler ultrasound result showed that some semen might ejaculate externally by passing through the initial stricture area, while some semen continued to flow retrogradely into the bladder.
