Continuation of #146966: Hematuria due to kidney stones?


I would like to ask the doctor about my kidney stones (2-3 stones approximately 0.25 cm) that were checked over a month ago.
It seems they haven't passed yet.
About a week ago, I noticed hematuria (blood in urine), which returned to normal after drinking water for a day or two.
Then, about a week later, hematuria reappeared.
This morning, I experienced some cramping pain near the bladder, but my urine was normal in color.
After taking Buscopan, the pain subsided after half an hour, but I noticed hematuria again.
This time, the blood in my urine looks different; it is brighter red compared to the previous darker reddish-brown color.
On one occasion, there was a 1 cm long, 0.1 cm thin blood streak in my urine, and the hematuria has lasted quite a while, continuing into the evening without lightening in color.
Should I go to the hospital for other medications, or is this just a symptom of passing the stones?

TT, 20~29 year old female. Ask Date: 2019/06/25

Hello: The passage of stones is usually accompanied by hematuria.
Please schedule a follow-up appointment to check the location of the stones (to see if there has been any improvement).
Wishing you good health.

When it comes to the presence of blood in urine (hematuria), especially in the context of kidney stones, it is essential to consider various factors that could contribute to this condition. Based on your description, it seems that you have been experiencing recurrent episodes of hematuria, accompanied by some discomfort near the bladder, and the color of the blood in your urine has varied from dark red to bright red. This situation raises several important questions regarding the underlying causes and the appropriate course of action.

Firstly, it is crucial to understand that hematuria can arise from multiple sources within the urinary tract, including the kidneys, ureters, bladder, and urethra. In your case, the presence of kidney stones could indeed be a contributing factor. Kidney stones can cause irritation and damage to the lining of the urinary tract as they move, leading to bleeding. The fact that you have experienced blood in your urine following episodes of pain suggests that the stones may be causing trauma to the urinary tract.

The change in the color of your urine from dark red to bright red is also noteworthy. Dark red urine may indicate older blood, while bright red urine typically suggests fresh bleeding. The presence of blood clots or strands in your urine could further indicate that there is active bleeding occurring, possibly due to the movement of stones or irritation of the urinary tract.

Given that you have experienced these symptoms for an extended period, it is essential to seek medical attention. While it is possible that the blood in your urine is related to the passage of kidney stones, other potential causes must be ruled out. These can include urinary tract infections (UTIs), bladder or kidney tumors, or other underlying conditions that may not be immediately apparent through imaging studies.

In terms of treatment, if you are experiencing significant pain or persistent hematuria, it is advisable to visit a healthcare provider for a thorough evaluation. This may include additional imaging studies, such as a CT scan, to assess the status of your kidney stones and to check for any other abnormalities in the urinary tract. Depending on the findings, your doctor may recommend different treatment options, which could range from conservative management with increased hydration and pain control to more invasive procedures if necessary.

Regarding the use of medications like Buscopan, which is an antispasmodic, it can help relieve discomfort associated with urinary tract spasms. However, it is essential to address the underlying cause of your symptoms. If the blood in your urine persists or worsens, or if you develop additional symptoms such as fever, chills, or worsening pain, you should seek immediate medical attention.

In summary, while your symptoms may be related to kidney stones, it is crucial to rule out other potential causes of hematuria. A comprehensive evaluation by a healthcare provider will help determine the appropriate course of action and ensure that any serious conditions are addressed promptly. Remember that timely medical intervention is key to managing urinary tract issues effectively.
