Summary
Balloon dilatation offers a less invasive treatment option for ureteral strictures, with a 47% success rate. This endourologic technique is recommended as a first-line therapy, with re-dilatation or surgery as alternatives for unsatisfactory outcomes.
Area of Science:
- Urology
- Interventional Radiology
Context:
- Ureteral strictures often require intervention.
- Minimally invasive techniques are preferred over open surgery.
Purpose:
- To evaluate the efficacy of balloon dilatation for ureteral strictures.
- To analyze outcomes based on stricture etiology.
Summary:
- 77 balloon dilatations were performed in 74 patients with ureteral strictures, primarily postoperative or inflammatory.
- The overall success rate was 47%, with partial improvement in 17% and failure in 36%. Postoperative strictures showed slightly better response.
- Balloon dilatation is less invasive, has low morbidity, and shorter hospitalization compared to open surgery.
Impact:
- Endourologic techniques like balloon dilatation reduce the need for invasive conventional surgery.
- Balloon dilatation is a viable first-line treatment for ureteral strictures.
- Re-dilatation or open surgery can be considered for persistent cases.
