There are several possible reasons for urinary ejaculation: first, the patient has a history of urethral surgery, having had an electrodesection of the prostate or bladder neck incision can cause reverse ejaculation. Because the urethra is open after the pressure in the bladder is reduced after surgery, semen will reverse into the bladder during ejaculation, and there will be no semen discharge during sexual intercourse. However, semen can be found in the urine, and this is a common complication after urethral surgery. Secondly, when suffering from diseases such as urethritis, urethral stricture, urinary tract infection or urethral stones, which cause elevated resistance in the urethra, semen cannot be discharged normally during ejaculation, but enters the bladder and is discharged with urine. However, it is often accompanied by symptoms such as frequent urination, urgent urination and painful urination, which need to be diagnosed through routine urinalysis, urethroscopy and other examinations. Finally, chronic prostatitis, testicular epididymitis and other diseases may also lead to the phenomenon of retrograde ejaculation and urinary seminal emission. You should visit the urology department of the hospital in time to identify the cause and then target treatment.
