Recurrent Blood in Urine After UTI Treatment: What to Know - Urology

After the inflammation of the urethra has healed, hematuria has started again?


Two weeks ago, my father had hematuria due to a urinary tract infection and was hospitalized for three days.
After that, he took antibiotics for two weeks and just stopped the medication a week ago.
However, today he started having hematuria again, and he doesn't have many other symptoms (last time he had no abdominal pain but did have a fever).
Could this be a recurrence of the infection, or could it be something more serious? I'm really worried...

Hello: It may be a recurrence of infection, as some cardiovascular medications can cause hematuria.
This should be taken into consideration, especially since visible hematuria in individuals over 45 years old warrants a bladder examination to rule out the possibility of any lesions after infection control.
Wishing you good health.

Recurrent blood in urine after treatment for a urinary tract infection (UTI) can be concerning, and it's understandable that you are worried about your father's health. There are several factors to consider when evaluating the situation.

Firstly, it is important to recognize that blood in the urine, or hematuria, can have various causes. In the context of a recent UTI, it is possible that the blood is a result of the infection itself, especially if the infection was severe or if there was any irritation or damage to the urinary tract. UTIs can cause inflammation and irritation of the bladder and urethra, which may lead to bleeding.
However, since your father has completed a course of antibiotics and is now experiencing blood in his urine again, it raises the possibility of a recurrence of the infection. UTIs can recur, particularly if the initial infection was not completely eradicated or if there are underlying issues that predispose him to further infections. Factors such as anatomical abnormalities, kidney stones, or other urinary tract obstructions can contribute to recurrent UTIs.

Another possibility to consider is that the blood in the urine could be due to a different underlying condition unrelated to the UTI. For example, conditions such as bladder stones, tumors, or even kidney issues could also cause hematuria. Given that your father had a UTI, it is also essential to rule out any complications that may have arisen from the infection, such as pyelonephritis (a kidney infection) or other urinary tract issues.

In terms of next steps, it is crucial for your father to follow up with his healthcare provider. A thorough evaluation is necessary to determine the cause of the recurrent hematuria. This may include a urinalysis to check for signs of infection, imaging studies such as an ultrasound or CT scan to visualize the urinary tract, and possibly a cystoscopy to directly examine the bladder and urethra.

It is also important to monitor for any additional symptoms. If your father experiences fever, chills, flank pain, or any other concerning symptoms, he should seek medical attention promptly. These could indicate a more serious infection or complication that requires immediate treatment.

In summary, recurrent blood in urine after a UTI treatment could be due to a recurrence of the infection, complications from the previous infection, or an entirely different underlying condition. It is essential to consult with a healthcare provider for a comprehensive evaluation and appropriate management. Early intervention can help prevent potential complications and ensure your father's health is adequately addressed.
