INVx for Bladder Trauma
INVx for Bladder Trauma
- Plain abdominal Film
Reveals evidence of pelvic fracture.
INVx for Bladder Trauma
- Ascending cystogram
Ascending cystogram in Bladder Trauma
Ascending cystogram in Bladder Trauma
- Indication
- Ascending cystogram should be sought in every case of suspected bladder injury with hematuria.
Ascending cystogram in Bladder Trauma
- Method
- 200- 300 of water-soluble contrast are infused into the bladder (by gravity) and evidence of extravasation is noticed.
Ascending cystogram in Bladder Trauma
- Findings
Ascending cystogram in Bladder Trauma
- PM Film
PM film is very important for demonstration of extravasation that would be otherwise masked by the bladder contour.
INVx in Bladder Trauma
- Pelvic CT
Could be helpful in detecting associated injury.

Etiology of Obstetric Trauma
Pathology of Obstetric Trauma
- The fistula could be either posterior or domal.
- It may involve the trigone and may rarely involve one of the ureters.
Dx of Obstetric Trauma
Dx of Obstetric Trauma
- Symptoms
Urinary leakage following vaginal delivery or CS:
- Within days to few weeks after the injury.
Dx of Obstetric Trauma
- Vaginal Examination
May detect a defect in the vaginal wall.
Dx of Obstetric Trauma
- INVx
TTT of Obstetric Trauma
TTT of Obstetric Trauma
- conservative
Urethral catheter for 2 weeks may be tried once leakage starts (as early as possible).
- This usually works if the fistula is small.
TTT of Obstetric Trauma
- Surgery
Def of Exercise Hematuria
- Joggerβs hematuria: is a term describing post exercise hematuria most commonly seen in marathon runners.
- Foreign body in the bladder.

- Normal Landmarks of Urethra in anterograde urethrogram
- Bladder neck is opened and the verrumontanum is visualized.
- The cone of the bulbar urethra is not seen.

- Hemorrhage.
- Sepsis and infection.
- Urethral stricture.
