Blood in urine with kidney stones is mainly caused by bleeding after the kidney stones damage the local mucosa. First of all, sodium bicarbonate can be applied IV, sodium bicarbonate has the effect of alkalizing the urine and preventing the blood from blocking the urethra. Secondly, patients should be instructed to drink more water or intravenous fluid replacement, which will increase the urine and flush the urethra. Once again, the management of kidney stones is the centerpiece of treatment. When the stone is less than 5mm, medications such as lithotripsy granules and potassium citrate can be given, along with scopolamine elimination to treat the stone, and the chances of it coming out on its own are higher. When the stone is larger than 5mm and smaller than 20mm, it can be treated with extracorporeal shock wave lithotripsy. If the stone is larger than 20mm, especially if the stone is irregular in shape, such as antler-shaped, you need to resort to percutaneous nephrolithotomy or open surgery.
