You mean you have urinary bleeding that caused you unable to urinate? If so, a catheter should be inserted to your bladder through your urethra and washed with saline to flush down the blood clots.
You have no urine output since the impaction? Do you feel abdomen fullness now? If you can't have normal urine output, you need to take catheterization to release the urine. And further examinations such as ultrasound and CT are needed for diagnosis.
