Hematuria due to kidney stones?


Hello Doctor, on the night of March 3rd, I suddenly felt a sharp pain in my lower left abdomen while sleeping.
The next morning, I noticed significant hematuria (cola-colored urine) in the bathroom.
Since then, I have experienced mild, persistent discomfort in my lower left abdomen, and occasionally, I have had blood in my urine (red).
On March 6th, I visited the hospital where an X-ray was taken, revealing a suspected stone in my lower left abdomen.
The doctor prescribed medication to help pass the stone, and I also had blood tests, urinalysis, and arrangements for an ultrasound and urine flow study.
I am scheduled to return for a follow-up on March 29th to review the results.
I would like to ask a few questions: 1.
Are these symptoms indicative of a kidney stone? (The stone has not yet passed, and I occasionally have hematuria, but the pain is not severe, and my urine output is normal.) 2.
Is it concerning that the follow-up appointment is so far away?

Hello: 1) This should be classified as symptoms of nephrolithiasis.
2) Some treatments for kidney stones require follow-up over a period of time.
If there are no issues, please return for your scheduled follow-up.
If there are any changes, you may come in earlier, such as experiencing fever, difficulty urinating, or persistent severe hematuria.
Wishing you good health.

Hello! Thank you for your detailed inquiry regarding your symptoms and concerns about blood in your urine, particularly in relation to kidney stones. Let's break down your questions and provide some insights based on medical knowledge.

1. Is this a symptom of kidney stones?
Yes, the symptoms you are experiencing, particularly the presence of blood in your urine (hematuria) and the pain in your left lower abdomen, can indeed be indicative of kidney stones. Kidney stones can cause irritation and damage to the lining of the urinary tract, leading to bleeding. The fact that you have noticed a "cola-colored" urine suggests that there is a significant amount of blood present. While kidney stones often cause severe pain, especially when they move or obstruct the urinary tract, it is not uncommon for some individuals to experience only mild discomfort or even no pain at all, especially if the stone is small or not causing a blockage.
2. Is it concerning that the follow-up appointment is scheduled for March 29?
The timeline for follow-up appointments can vary based on the healthcare provider's assessment of your condition and the urgency of your symptoms. In your case, since you have already experienced significant symptoms, including blood in your urine, it would be advisable to seek a sooner follow-up if your symptoms worsen or if you experience increased pain, fever, or any other concerning symptoms. Blood in the urine, especially if persistent, warrants closer monitoring. If you feel that your symptoms are not being adequately addressed or if you have ongoing concerns, it is perfectly reasonable to seek a second opinion or request an earlier appointment.


Additional Considerations:
- Diagnostic Tests: The X-ray and ultrasound you mentioned are standard procedures for assessing kidney stones. While X-rays can identify certain types of stones, they may not detect all stones, particularly those made of uric acid. An ultrasound is a useful tool for visualizing the kidneys and urinary tract without radiation exposure. If your symptoms persist, further imaging studies, such as a CT scan, may be warranted for a more comprehensive evaluation.


- Management of Kidney Stones: If a stone is confirmed and is causing symptoms, treatment options may include medication to help pass the stone, increased fluid intake to facilitate stone passage, or procedures like lithotripsy (shock wave therapy) or ureteroscopy if the stone is too large to pass naturally.
- Blood in Urine and Other Causes: While kidney stones are a common cause of hematuria, other potential causes include urinary tract infections (UTIs), bladder or kidney infections, trauma, or even tumors. Given that you have experienced persistent blood in your urine, it is essential to rule out these other conditions through appropriate testing.

- Lifestyle Modifications: If you are diagnosed with kidney stones, dietary changes may be necessary to prevent future stones. This can include increasing fluid intake, reducing sodium, and modifying your intake of certain foods based on the type of stones you have.

In summary, while your symptoms are consistent with kidney stones, it is crucial to maintain open communication with your healthcare provider and advocate for your health. If you feel that your concerns are not being addressed adequately, do not hesitate to seek further evaluation. Your health and well-being are paramount, and timely intervention can prevent complications.
