Endoscopic balloon dilatation offers a minimally invasive option for primary obstructive megaureter (POM) in children. This technique shows promising short-term success, potentially avoiding open surgery.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
Background:
- Primary obstructive megaureter (POM) is a congenital condition.
- Traditionally managed with open ureteral reimplantation surgery.
- Endoscopic balloon dilatation presents an alternative approach.
Purpose of the Study:
- To evaluate the efficacy of endoscopic balloon dilatation for POM.
- To assess outcomes in pediatric patients treated with this technique.
Main Methods:
- Seven pediatric patients with POM underwent balloon dilatation.
- Procedures performed using infant cystoscope and dilating balloon under fluoroscopy.
- Follow-up included ultrasonography and MAG-3 renography.
Main Results:
- High clinical satisfaction reported.
- Reduced obstruction observed in five patients post-procedure.
- One patient required repeat dilatation; another experienced a urinary infection.
Conclusions:
- Endoscopic balloon dilatation demonstrates good short-term results for POM.
- Further long-term follow-up is needed to establish definitive indications.
