Ureteral stones


Hello, doctor.
Four days ago, I underwent ureteroscopy for stone removal.
This morning, I noticed that my urine was dark red, and it has since been brown.
Is this normal?

After undergoing ureteroscopy for stone removal, it is not uncommon to notice changes in urine color, including dark or reddish hues. This can be attributed to several factors related to the surgical procedure and the body's healing process.

Firstly, the presence of blood in the urine, known as hematuria, is a common occurrence following urinary tract surgeries. The surgical manipulation of the ureters and kidneys can lead to minor trauma, resulting in bleeding. This bleeding may not be significant enough to cause alarm but can manifest as a change in urine color. Initially, the urine may appear bright red, which can gradually transition to a darker brown or tea-like color as the blood gets diluted and the healing process progresses.

In the first few days post-surgery, it is typical to experience some degree of hematuria. However, if the urine remains persistently dark or if you notice clots, increased pain, or any signs of infection (such as fever, chills, or foul-smelling urine), it is crucial to contact your healthcare provider. These symptoms could indicate complications such as a urinary tract infection or significant bleeding that may require further evaluation.

Moreover, the presence of dark urine can also be influenced by factors unrelated to the surgery itself. Dehydration can concentrate the urine, leading to a darker appearance. It is essential to maintain adequate hydration, especially after surgery, to help flush out the urinary system and promote healing.

In terms of post-operative care, here are some recommendations:
1. Hydration: Drink plenty of fluids to help dilute the urine and flush out any residual blood or debris from the urinary tract. Aim for at least 8-10 glasses of water a day unless otherwise directed by your physician.

2. Pain Management: If you experience discomfort, over-the-counter pain relievers may be recommended. However, consult your doctor before taking any medication, especially if you have other health conditions or are on other medications.

3. Activity Level: Avoid strenuous activities and heavy lifting for a few weeks post-surgery to allow your body to heal properly. Gentle walking is encouraged to promote circulation.

4. Monitoring Symptoms: Keep an eye on your urine color and any accompanying symptoms. If you notice persistent dark urine, significant pain, or any other concerning symptoms, reach out to your healthcare provider for further evaluation.

5. Follow-Up Appointments: Attend all scheduled follow-up appointments with your urologist to monitor your recovery and address any concerns that may arise.

In summary, while dark or reddish urine can be a normal part of the recovery process after ureteroscopy, it is essential to remain vigilant for any signs of complications. If you have any doubts or if your symptoms worsen, do not hesitate to seek medical advice. Your healthcare provider is best equipped to assess your situation and provide personalized recommendations for your recovery.
