[|Human|] My husband had right flank pain like kidney stone was passing and he felt like there was something moving in the penis as well. A couple of days later the pain was gone, but he has had two instances of blood in semen and none in the urine when he urinates. Is this a prostate problem or could it be that the stone irritated the urethra? If so, why does it not bleed while urinating?
[|AI|]  Hi, Thank you for using Chat Doctor. I can understand your concern about your husbands' health. Right flank pain along with feeling of something moves in penis can be attributed to stone moving down in urinary system. Irritation/Inflammation anywhere in urinary system could lead to bleeding. The presence of blood in semen and not in urine suggest that possibilities of prostate condition, but it is also possible that minor amount of blood may dilute in urine and not become visible. Get urine routine micro examination and ultra-sonogram of pelvis.  If your husbands age is more than 40 than better to consult doctor and get prostate examination. Watch for few symptoms like fever, blood in urine, tenderness or pain in scrotum/lower back, if develops consult doctor. Hope this will help you. Regards.
