Summary
Balloon dilatation offers a successful minimally invasive treatment for ureteric strictures, particularly in fresh post-operative cases. Success rates depend on stricture age, length, and cause, with tuberculosis cases showing lower efficacy.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Endourology
Background:
- Ureteric strictures present a significant clinical challenge.
- Surgical intervention has historically been the primary treatment modality.
- Minimally invasive alternatives are sought to improve patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of balloon dilatation for treating ureteric strictures.
- To identify factors influencing the success of this minimally invasive technique.
Main Methods:
- A prospective evaluation of 16 patients with ureteric and pelviureteric junction strictures.
- Patients underwent balloon dilatation procedures starting from June 1998.
- Data collected included patient demographics, stricture characteristics, and treatment outcomes.
Main Results:
- Overall success rate for balloon dilatation was 69%.
- Strictures secondary to prior surgery demonstrated a near 100% success rate.
- Cases of genitourinary tuberculosis had a 50% success rate.
Conclusions:
- Key factors influencing success include stricture age, length, and etiology.
- Balloon dilatation is a viable and attractive alternative to surgery for select patients.
- Fresh post-operative or post-inflammatory strictures show promising results with this technique.
