Currently, more and more patients are coming to the urology department for hematuria. Generally speaking, hematuria is called “visual hematuria”, which refers to the presence of more red blood cells in the urine, which can be seen as light red or bright red with the naked eye.
The painful, frequent, urgent and other discomforts of hematuria are more likely to attract attention and prompt medical attention. The painless hematuria is often without other discomfort, and the hematuria can disappear temporarily without treatment, so it is easy to give patients the illusion of “getting better”, especially after taking certain drugs and prescriptions, which may be mistaken for effective treatment, thus delaying the best time for diagnosis and treatment.
In fact, this kind of intermittent and painless hematuria is often a warning signal of urinary tract cancer. For example, about 60% of kidney cancer patients have painless hematuria, while about 80% of bladder cancer patients have painless hematuria. Once hematuria suddenly worsens or other discomforts (such as lumps, back pain, frequent urination, urinary urgency, accompanied by blood clots, etc.) appear, it often indicates that the tumor enters advanced stage. Old Wang found red urine 1 year ago. At that time, he thought it was inflammation and took some anti-inflammatory drugs casually, and the color of urine became clear. Although he often found hematuria in the future, but no other discomfort, he also did not take it seriously. But recently, he found that there were often blood clots of different sizes in his urine, and taking anti-inflammatory drugs did not help, so he rushed to our hospital for consultation. We all know that in early stage of bladder cancer, minimally invasive treatment such as bladder tumor electrosurgery has good effect and quick recovery, so Lao Wang missed the best time for treatment.
Therefore, patients with painless hematuria, especially the middle-aged and elderly, should pay attention to and go to regular hospitals in time. Before finding the cause, malignant tumors of the urinary tract cannot be easily excluded so as not to miss the best time for treatment.
