Urinary excretion of foreign objects?

Thank you, Dr.
Lin, for your previous response.
I have some additional concerns regarding my father's health:
1.
On one occasion, my father experienced dark-colored urine accompanied by severe pain.
We suspect it might be related to his recent consumption of tofu and spinach.
What is your opinion on this matter?
2.
After undergoing surgery for rectal cancer, he has developed an abscess at the surgical site, experiences discomfort while urinating, and has persistent discomfort around the bladder.
Recently, he has been experiencing significant rectal bleeding, making it difficult for him to sit.
Could you please provide your insights on this situation? Are these symptoms considered normal? Is it common for patients who have been diagnosed and treated for rectal cancer to experience similar issues?
We hope to receive your prompt response.
Thank you for your time.

Hello: 1.

2.
If you feel uncomfortable after surgery, you can ask the physician to prescribe some medications for symptom control.
Patients should pay attention to keeping the affected area clean; if there is already pus discharge, it is best to consult a physician for treatment.

More Info

After rectal cancer surgery, patients may experience a variety of unusual symptoms, including changes in urination and discomfort in the pelvic area. Let's address your father's concerns one by one.

1. Black Urine and Pain: The appearance of black urine can be alarming and may indicate several underlying issues. While dietary factors, such as consuming tofu and spinach, can sometimes affect urine color, the combination of black urine and severe pain should not be overlooked. Black urine can result from the presence of blood, certain medications, or even metabolic conditions. In the context of recent surgery, it could suggest bleeding or a reaction to medications. It is crucial to consult a healthcare professional immediately to rule out any serious complications, such as urinary tract infections or damage to the urinary system.

2. Discomfort and Bleeding: Following rectal cancer surgery, it is not uncommon for patients to experience discomfort in the pelvic area, especially if there has been any surgical manipulation of surrounding tissues. However, persistent pain, especially accompanied by significant bleeding from the anus, is concerning. The presence of pus (indicating infection) and blood can suggest complications such as abscess formation or an infection at the surgical site. These symptoms are not typical and warrant immediate medical evaluation.
The discomfort during urination and the sensation of pressure around the bladder can be related to inflammation or irritation of the bladder or urethra, possibly due to surgical trauma or infection. It is essential to communicate these symptoms to the healthcare team, as they may need to perform diagnostic tests, such as imaging or laboratory tests, to assess the situation accurately.

In summary, while some discomfort and changes in urination can occur after rectal cancer surgery, the symptoms your father is experiencing—black urine, severe pain, significant bleeding, and discomfort—are not typical and should be evaluated by a medical professional as soon as possible.
Additional Considerations:
- Follow-Up Care: After any cancer surgery, regular follow-up appointments are crucial for monitoring recovery and addressing any complications. Patients should be encouraged to maintain open communication with their healthcare providers about any new or worsening symptoms.

- Potential Complications: After rectal surgery, complications can include infections, bowel obstructions, or issues related to the urinary tract. It is essential to be vigilant about these symptoms and seek prompt medical attention.

- Second Opinions: If there are concerns about the diagnosis or treatment plan, seeking a second opinion from a specialist in colorectal surgery or oncology can provide reassurance and additional insights into the management of symptoms.

In conclusion, your father's symptoms should be taken seriously, and prompt medical evaluation is necessary to ensure appropriate treatment and care.
