Abnormal phenomenon: (1) seminal vesiculitis: after prostate surgery without paying attention to hygiene, retrograde infection induced seminal vesiculitis, which can lead to the emergence of spermatorrhea, usually accompanied by pain in the lower abdomen, urinary urgency, urinary frequency, bloody semen and other phenomena.
