If you have a bloated abdomen and are unable to urinate on your own, consider prostatitis or urinary tract infection, especially in older people, because prostate enlargement, prostate congestion, edema is more serious when it will compress the urethra, resulting in the inability to urinate. If there is a stone in the urinary system, the stone is relatively large and causes obstruction in the urethra at the narrow part of the urethra, which can also lead to abdominal distension and inability to discharge urine. In case of general anesthesia surgery, when the anesthesia is not fully awake, the anesthetic inhibits the bladder function, which can also lead to abdominal distension and inability to urinate, and in case of serious urinary tract infection, the early stage is dominated by frequent, urgent and painful urination. You can use a hot water bag to warm the small abdomen, listen to the sound of running water, abdominal massage to induce urination, and if necessary, indwelling a catheter, then promptly find the cause and deal with it.
