Performing VCUG After Urethroplasty

Timing of VCUG After Urethroplasty

For optimal assessment of urethral healing after urethroplasty, a voiding cystourethrogram (VCUG) should be performed approximately 2-3 weeks following surgery to evaluate for complete urethral healing before catheter removal 1
A urinary catheter should be placed following urethroplasty to divert urine from the surgical site and prevent urinary extravasation 1
VCUG is typically performed 2-3 weeks following open urethral reconstruction to assess for complete urethral healing 1, 2

The VCUG should include a static cystogram to determine the competency of the bladder neck mechanism, the level of the bladder neck in relation to the symphysis pubis, and the assessment of the proximal extent of any potential injury 3, 4

For pelvic fracture urethral injury (PFUI) cases, VCUG combined with retrograde urethrography (RUG) is essential for preoperative planning 3, 4
In complex cases or those with suspected proximal injury, consider additional imaging, including antegrade cystoscopy and pelvic CT or MRI to assess degree of malalignment and defect length 3, 4
