What is the cause of bleeding from the urethral catheter?

Patient's question:

Medical Description: The patient is a 28-year-old male with a previously healthy condition. Last night, after sexual intercourse and ejaculation, he did not urinate immediately. Fearing that semen might leak, he used paper money to cover his penis. In the middle of the night, he urgently got up to urinate but forgot to remove the paper before doing so. He did not turn on the light and did not see the paper. Unable to urinate, he experienced pain at the urethral opening, promptly removed the paper, but the pain was already severe. He urinated while still in pain but thought nothing of it. At 7 a.m. the next morning, he noticed blood at the urethral opening and a small amount of blood clots being flushed out during urination, accompanied by a stinging sensation. However, there was no blood in the urine. It is estimated that the bleeding was caused by a tear in the urethra between the middle and front of the penis. The hospital doctor examined the surface and found no issues, but a urine test revealed three+ red blood cells. The doctor mentioned that due to long waiting times and the high cost of blood tests and urethral endoscopy (hundreds of dollars), they would prescribe him to take Paeonia lactiflora tablets and Ciprofloxacin tablets for three days as a temporary measure.

Doctor's answer:

Hello, the occurrence of hematuria is generally pathological conditions, such as nephritis, renal vascular system disorders, urinary tract infections, tumors, trauma, stones, etc. However, transient hematuria can also occur after upper respiratory tract infections or other febrile diseases, after dehydration, or after intense exercise, and it is considered a normal phenomenon. It is recommended to undergo a urinalysis.
It is suggested that your husband further undergo a urinalysis, a prostatic fluid routine examination, and a B-ultrasound of the urinary and reproductive system to confirm the cause and receive treatment. Drink plenty of water, avoid spicy and irritating foods, quit smoking and alcohol, and pay attention to personal hygiene.
It is recommended that you actively visit the urology department of a hospital for a thorough examination and receive symptomatic treatment as soon as possible based on the examination results.
