What Causes Blood In Urine And Pain While Urinating?
Question: I have been diagnosed with hemaduria with rbc/hpf count of 51-100. I have had a CT, cystoscopy, prostate bioposy and a urine test for microscopic cancer cells, all with negative results. I have BPH. Cause of hemaduria has not yet been discovered. I was also shocked the last time I went to the lab for urine analysis and pinched my penis to stop urine flow long enough to remove the cup without spilling urine on it. When I released to hold on the penis, I had a pain as the urine began to flow and observed visible blood mixed in the urine. The blood is only visible when I constrict the urethea.
I do not have access to uploads but I can tell you that my last blood and urine analysis was XXXXXXX Feb 20th. PSA was 2.55, urine appearance was clear, color was yellow, bilirubin was neg, erythrocytes 0-2, glucose neg, hemoglobin neg, ketones, neg, leukocyte esterase trace, leukocytes 0-2, nitrite neg, ph 5.0, protein neg, specific gravity 1.014 and urobilinogen ,<2.0. Results from 12/16/13, Creatinine was 1.0, BUN 17, EFGR 75, hyaline casts 0-4, wbc 0-2 and rbc 51-100. Hope this helps.

Detailed Answer:
Hi,
I have gone through your medical history and lab reports carefully. I have noticed that in your urine test of 12/16/2013, the rbc were 51 - 100; while the readings of Feb 20th showed rbc = 0-2.
It is quiet a big difference. And it is for good fortunately. As other parameters of urine analysis in both reports resulted normal; the only explanation could be urethral problems (narrowing) due to enlarged prostate as long as all tests for cancer resulted negative.
To my opinion, you are having genital issues (perhaps chronic urethritis). I suggest to get the urethral fluid cultured and run sensitivity testing.
Another explanation could be tiny stones passing by the urinary pathways. As you are not mentioning in you test reports about UTI/kidney stones/crystals; I suggest to discuss it further with your doctor.
Trauma or local injury should also get ruled out as possible cause.
Hope it helped! Let me know if you have further queries!

Thank you Dr. Albana.
Hemaduria is one issue but do you have any comments on the probable cause of the visible blood when I purposefully restrict the urine flow to remove the lab cup? The visible blood is accompanied by a stinging sensation when the flow resumes. The blood is microscopic and not visible to me until this restriction. After I have finished that particular urine flow, the next time I urinate, again there is no visible blood. Weird huh?

Causes to visible blood when restricted urine flow
Detailed Answer:
Hi again,
Thank you for following up.
What you are experiencing is not that weird. To me, it sounds like a "traumatic injury" in your urine flow pathways caused by purposefully restriction of the urine flow when removing the lab cup.
This also explains why you are not having visible blood the next time you have to urinate without restriction.
Another cause could also be related to urethritis and chronic inflammation of your genitalia. When you have such restrictions, as urine flow and seminal flow have the same pathway and opening, blood comes visible.
Furthermore, although blood is visible, the microscopic examination of urine shows only few erythrocytes, making me thinking that the blood is not that much in your urine pathways, but coming from your genitalia. That is why I asked to get checked for urethritis also.
Small crystals can also cause laceration of urine pathways, resulting in bleeding. As per the lab tests you provided, I did not read anything about crystals in urine. That should be considered too.
Let me know if you have further queries!
