Transrenal ureteral occlusion using a detachable balloon
Urologic Radiology
|January 1, 1984
Summary
Detachable silicone balloons for ureteral occlusion offer palliation for urinary fistulas and severe dysuria in advanced pelvic cancers. Effective blockage requires concurrent external nephrostomy drainage.
Area of Science:
- Urology
- Interventional Radiology
Background:
- Urinary fistulas and severe dysuria are challenging complications in advanced pelvic malignancies.
- Current treatments may be invasive or insufficient for palliation.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous transrenal ureteral occlusion using detachable silicone balloons.
- To assess the technique as a palliative measure for specific urological conditions.
Main Methods:
- Percutaneous transrenal ureteral occlusion was performed in 20 patients using detachable silicone-filled balloons.
- Indications included large urinary fistulas and severe dysuria in advanced pelvic malignancies.
- Contralateral kidney non-function was induced in 6 patients to avoid bilateral nephrostomy.
Main Results:
- Ureteral blockage was insufficient in 3 patients due to frequent tube obstruction.
- Two dislocated balloons were successfully removed and replaced percutaneously.
- The procedure aimed to interrupt urinary flow down the ureter.
Conclusions:
- Percutaneous ureteral occlusion with detachable balloons can be a viable option for specific palliative scenarios.
- Successful ureteral occlusion necessitates well-functioning external nephrostomy drainage to ensure effective urinary flow interruption.
