If you have abdominal pain and urinary urgency, it is recommended to go to the hospital for examination to clarify the possible causes: 1. Infection of the urinary system, such as acute cystitis, can cause the above symptoms, which can be accompanied by painful urination or pain in the small abdomen. 2. Stones in the bladder or ureter can also cause abdominal pain with symptoms such as urinary urgency, urinary frequency or hematuria. 3. Tumors of the bladder can cause pain in the abdomen, because the tumor causes a reduction in the effective bladder capacity, so it can produce symptoms of urinary frequency and urgency, and can also be accompanied by symptoms of blood in the eyes, which need to be further ruled out by CT or cystoscopy of the urinary system. 4. Interstitial Cystitis can cause pain in the small abdomen accompanied by urinary urgency, often in the state of holding urine, the pain in the small abdomen will be aggravated and may be accompanied by hematuria, which requires cystoscopy or bladder hydrodilation under anesthesia to further confirm the diagnosis.
