THE TRANSURETHRAL TREATMENT OF PRIMARY HIGH GRADE VESICOURETERAL REFLUX IN CHILDREN

Vesicoureteral reflux constitutes up to 30 percent of anomalies of urinary tract among children and the late diagnosis is characterized by the complications, such as, the scarring in the kidneys. Although the conservative management of first and second-grade vesicoureteral reflux is effective between 60 and 70 percent of cases, in advanced grades, in the absence of operative intervention, the disease may lead to recurrent pyelonephritis with potentially irreversible kidney damage. For this reason, early diagnosis and operative intervention are useful for preventing recurrent urinary tract infections and kidney parenchyma damage. Although the minimally invasive transurethral correction method has shown high levels of effectiveness in the early and middle grades of vesicoureteral reflux in children, it also demonstrates effective results in the advanced grades of the disease. The study aims to select the method of endoscopic treatment and analyze the results based on the causes of disturbances in the antireflux mechanism of the ureterovesical segment. For this purpose, from 2019 to 2023, endoscopic treatment was performed in 65 children (90 ureters) at the clinic of the Tashkent Pediatric Medical Institute, department of pediatric urology. Based on the results of the study, both short-term and long-term outcomes of the surgery were analyzed for 65 patients. It was also confirmed that endoscopic correction is an effective method that leads to successful results in cases of high-grade vesicoureteral reflux.
