What about urine retention?

If you show acute urinary retention, you must go to the urology clinic of the local 3A public hospital for treatment. You can choose to insert a catheter and empty the urine in the bladder. This can reduce the pressure in the bladder and prevent the patient from showing severe abdominal pain. The patient will be difficult to show tolerance, but in the catheter, each time the urine, especially when acute urinary retention, each urine volume should not exceed 500 ml, if more than 500 ml after it is easy to cause bladder relaxation contraction.
