Abstract
Introduction: Vesicoureterorenal reflux (VUR) is one of the most common congenital urological anomalies, with an incidence of ~1%. Different surgical techniques are used in pediatric patients – endoscopic, conventional, laparoscopic and robot-assisted. The first line of treatment in children with reflux requiring surgery is an injection of bulking agents. There are two techniques for endoscopic treatment of reflux: subureteral injection (STING) and intraluminal injection (HIT).
Objectives: The aim of this case report is to present the STING technique of endoscopic treatment in patients with vesicoureterorenal reflux.
Materials and methods: From July 2021 to December 2024, we operated on 42 patients with vesicoureterorenal reflux (VUR) using the STING technique. 11 of the patients had bilateral form, and in 31 the reflux was one-sided. The average volume of injected bulking agent was between 0.7ml to 1ml.
Results: The average operative time was 15 minutes, without using a urethral catheter in any case. All of the patients were discharged the next day, having antibiotic treatment for 5 days and prophylaxis for one month. We have no intra- and postoperative complications. Six of the operated patients had a new febrile UTI with persisting reflux, which required further surgical treatment.
Conclusions: Endoscopic injection of bulking agents in children with vesicoureterorenal reflux is a first line of treatment because it is less traumatic and requires a shorter hospital stay. Subureteral injection (STING technique) is preferred due to its high success rate and low incidence of postoperative complications.
