The Goldman system1 is used:
| Injury type | Appearance |
| 1 | The posterior section of the urethra is stretched. Easily seen on urethrography and may be identified on CT by elevation of the prostatic apex |
| 2 | Posterior urethral injury with no involvement of the urogenital diaphragm |
| 3 | Posterior urethral injury with injury of the anterior urethra (crossing the urogenital diaphragm) |
| 4 | Bladder neck and proximal urethral injury |
| 4a | Bladder neck injury without urethral injury but with periurethral contrast |
| 5 | Anterior urethral injury only |
