The most common cause of stabbing pain in urination with hematuria in female patients is acute cystitis. Because the vagina, urethra and anus are very close to each other in women, the urethra is easily contaminated by the vagina and anus, which leads to urinary tract infections. Female patients with urinary tract infection mainly manifest as frequent, urgent and painful urination, burning and stinging in the urethra during urination, fleshly hematuria at the end of urination, and cramping and discomfort in the bladder area or perineum, when a routine urine examination is needed. If the white blood cell count in the routine urine is elevated, it is considered to be a urinary tract infection, and it is suggested that oral levofloxacin can be taken for 3 days. In addition, usually pay attention to drinking more water and urinating more often, and you can apply hot compresses to the bladder area when urinary frequency is severe. In addition, drink more than 2000ml of water daily and keep the perineum clean and hygienic.
