What is the reason for rectal bleeding after prostate surgery?

Patient's question:

Hello, doctor, why did I have blood in my urine these days after the prostate surgery I had two years ago?

Doctor's answer:

According to your description, this phenomenon is a common issue for patients who have undergone urological prostate surgery. There are generally a few possible reasons:
1. About two weeks after the prostate surgery, sudden heavy bleeding may occur due to the shedding of prostate crusts, which would require timely catheterization and bladder irrigation.
2. Most cases are caused by the patient not drinking enough water after surgery, leading to dysuria and hematuria. The solution is to encourage the patient to drink more water, with a daily intake of over 3000ml, which can help alleviate hematuria symptoms.
3. Patients may continue to experience hematuria for up to three months after surgery, particularly in terminal hematuria, which may be more severe. This is because the wound from the prostate surgery needs time to heal. Although transurethral resection does not leave an open wound, the surgery still creates a wound that requires a healing process.
I hope my explanation is helpful to you.
