Usually, the left abdominal pain of urination may be related to cystitis, ureteral stenosis, urethral stones and other causes.
1. Cystitis: mostly due to inflammation of the bladder mucosa caused by various pathogenic bacteria, due to the stimulation of inflammation can appear urinary pain, urinary urgency, urinary frequency and other phenomena.
2. Ureteral stenosis: Ureteral stenosis affects urine drainage, which in turn leads to dilatation of the ureter above the site of the lesion, thus causing pain. If the ureteral stenosis is on the left side, there will be pain on the left side of the abdomen when urinating.
3. Ureteral stones: usually caused by kidney stones discharging into the ureter and staying in its narrowing. If a stone develops in the ureter on the left side of the abdomen and scratches the urethral mucosa in the urethra, pain may occur, and in severe cases, bleeding may also occur.
In addition, the left abdominal pain of urination can also be seen in intestinal diseases, etc. It is recommended that the patient go to the hospital in time and follow the doctor’s instructions for treatment.
