Insights
Submucosal injection of Teflon (STING) offers a highly successful endoscopic treatment for vesicoureteral reflux in children. This minimally invasive approach achieved a 90% success rate after one injection, with higher efficacy in primary reflux cases.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Endourology
Background:
- Vesicoureteral reflux (VUR) is a common condition in children, potentially leading to kidney infections and damage.
- Traditional treatments for VUR include medical management and open surgical repair.
- Endoscopic treatment offers a less invasive alternative for managing VUR.
Purpose of the Study:
- To evaluate the efficacy and outcomes of endoscopic treatment for vesicoureteral reflux using submucosal injection of Teflon (STING).
- To assess the success rates of STING in different types of VUR and across multiple injections.
Main Methods:
- Retrospective review of 45 children (67 ureters) treated with STING between December 1992 and the study's reporting period.
- Analysis of success rates based on the number of injections and VUR grade (II and III).
- STING was considered for VUR cases unresponsive to one year of medical treatment.
Main Results:
- Overall success rate of 90% after one STING injection and 95% after two injections.
- Higher success rates observed in primary reflux (95%) compared to duplicated ureters (87.5%) and secondary reflux (75%) after one injection.
- STING was utilized for VUR grades II and III refractory to medical therapy.
Conclusions:
- Endoscopic treatment of vesicoureteral reflux with submucosal injection of Teflon (STING) is a safe and effective procedure in pediatric patients.
- STING demonstrates high success rates, particularly for primary VUR, and offers a viable option for cases refractory to medical management.
- The technique provides a minimally invasive solution with favorable outcomes, reducing the need for more complex surgical interventions.
Abstract:
We report our experience with the endoscopic treatment of vesicoureteral reflux by submucosal injection of Teflon (STING) in children. Since December of 1992, 45 children and a total of 67 ureters were treated. The overall success rate was 90% after one injection and 95% after two injections. The success rate was better in primary reflux with 95%, 87.5% in duplicated ureters and 75% in secondary reflux after one injection. Actually we treat the reflux grade II and III with STING when it doesn't improve after one year with medical treatment.
