Bladder mucosal tears during voiding cystourethrography in chronic renal failure.
Urologic Radiology
|January 1, 1986
Summary
Chronic renal failure patients may experience contrast intravasation/extravasation during voiding cystourethrography. Bladder mucosal changes in these patients may predispose them to injury, though sequelae were not observed.
Area of Science:
- Urology
- Nephrology
- Radiology
Background:
- Chronic renal failure (CRF) can impact bladder function.
- Voiding cystourethrography (VCUG) is a diagnostic procedure used in evaluating bladder and urethral abnormalities.
Purpose of the Study:
- To report the occurrence of contrast intravasation/extravasation during VCUG in patients with CRF.
- To investigate potential predisposing factors and outcomes associated with this event.
Main Methods:
- Retrospective review of 6 patients with CRF who underwent VCUG.
- Clinical follow-up and, in two cases, cystoscopic evaluation of bladder mucosa.
Main Results:
- Six patients with CRF developed contrast intravasation/extravasation during VCUG.
- Two patients showed diffuse mucosal tears on cystoscopy, which resolved on follow-up.
- No patients experienced symptoms or clinical sequelae.
Conclusions:
- The chronically unused bladder in CRF patients may have altered pathophysiology predisposing to mucosal injury during VCUG.
- Contrast intravasation/extravasation in this context appears to be a transient finding without significant clinical impact.
