Summary
Transrenal ureteral occlusion effectively interrupts urinary flow. Detachable balloons demonstrated superior permanent sealing compared to tissue adhesive in this study.
Area of Science:
- Urology
- Interventional Radiology
Background:
- Urinary tract obstruction requires management.
- Transrenal ureteral occlusion offers a minimally invasive approach.
Purpose of the Study:
- To evaluate the effectiveness and safety of transrenal ureteral occlusion.
- To compare tissue adhesive and detachable balloons for ureteral occlusion.
Main Methods:
- Transrenal ureteral occlusions performed in 83 ureters (76 patients).
- Two methods used: tissue adhesive (31 ureters) and detachable balloons (52 ureters).
- Follow-up ranged from 1 week to 61 months.
Main Results:
- Permanent occlusion achieved in 55% with tissue adhesive and 69% with detachable balloons after one procedure.
- Detachable balloons provided longer temporary occlusion (19.5 weeks vs. 2.5 weeks).
- Complications occurred in 7% of interventions, with four significant events.
Conclusions:
- Transrenal ureteral occlusion is effective and safe for selected patients.
- Detachable balloons are superior to tissue adhesive for ureteral occlusion.
