Dear XXXXXXX

Greetings from health care magic!!! I am Dr Thakker and shall be answering your question.

I can understand your anxiety about the blood in urine.

After reading the clinical history, the following are the possible causes of blood in the urine:

Traumatic catheterisation: The urethral epithelium is very delicate and can be damaged if the catheter is not inserted correctly. If a catheter of a large size is used, it can cause bleeding as well.

Urethral stricture: Chronic urethral catherisation leads to narrowing of the urethra. This can bleed during insertion.

Urethral stone: This can cause severe pain and blood in the urine.

Bladder malignancy: This is a remote cause in him given he has bleeding after catheterisation.

The next step is to get a retrograde urethrogram and diagnose the cause of bleeding. Platelet counts, APTT , PT/INR should also be done. I would recommend you to rush him to the ER because we don't want him to go into shock from blood loss.

I hope this helps you out. If you have any more questions, please do not hesitate to write back to me.

Yours sincerely,
Dr Thakker.
