Blood in semen and urine weeks after kidney stone

I'm a 33 yr. old male who had considerable blood in my urine periodically in the last year.  Tests for kidney stones (CT scan, IVP and scope into bladder) were negative, but a few weeks later, I had severe pain and increased blood in my urine.  After another week or two, I passed about a 1/4 inch kidney stone (95% Calcium Monohydrate, 5% Calcium Dihydrate).  The stone passed about a month ago.

I hadn't noticed any problems since the kidney stone passed, but for the last week or so, I've had visible blood (clots?) in my semen.

I haven't seen my urologist since I passed the kidney stone, but will be taking some additional blood tests this week (Glucose-fasting, Hemoglobin A1C and ASO-toter -- they were ordered before I passed the stone).

I also have ulcerative colitis, had strep throat 7 months ago and cared for my son with impetigo about 10 months ago.  The Dr. said he noticed a higher than usual (ASO toter(?)) from my blood test that he thought might have been related to the previous strep exposure.  

Can blood be present in the semen from the kidney stone passage about a month ago or are blood in semen and blood in urine separate events?

I have another urology apptmt in  couple weeks.  Should I go in sooner?  What questions should I ask my doctor?

Hello - thanks for asking you question.

Blood in the semen is known as hematospermia.  There are a variety of causes, including any prostate infection or disease, cancer, or infection.  It is possible that the blood can be from the kidney stone you passed, or a new kidney stone.

However, before attributing it to this, you should have it re-evaluated fully.  Tests for infection (i.e. a urinalysis) and STDs should be considered.  The imagining test of choice would be a transrectal ultrasound to evaluate structural abnormalities of the prostate gland, seminal vescicles, spermatic cord.  MRI of the prostate can also be considered as a second line test.

If negative, a repeat cystoscopy should be considered.

Followup with your personal physician is essential.
