Abstract

Objective: The aim of this study is exhibiting the factors affecting the outcomes of the surgical treatment of VUR by evaluating the demographics, radiologic findings, treatment options and complications.

Material and Methods: Patients who underwent VUR repair from 2007 to 2014 in our unit were included in this retrospective study approved by the local ethics review board. Age, gender, complaint, etiology and grade of VUR, grade of hydronephrosis, renal function, preferred surgical treatment (endoscopic injection - ureteroneocystostomy) method, treatment success rate and complication were collected from the patient records.

Results: A total of 276 patients were included. Endoscopic subureteric injection (STING) were performed in 220, ureteroneocystostomy were performed in 56 patients as a first intervention. 43 patients who had no improvement after STING were performed ureteroneocystostomy. The surgical success rate was 90.2% in patients without hydronephrosis and 72.3% in those with severe hydronephrosis. This rate was 88% in high-grade reflux patients, 98.3% in low/moderate-grade VUR, and 83% in patients with poor renal function and 94% in good and moderate patients. The success rate of surgical treatment was higher in primary VUR patients than secondary VUR (96% -85%). After the surgical treatment, the rate of improvement of bladder wall thickening was 52.2% and the rate of regression of hydronephrosis was 21.3%. Patients who required UNC after STING had higher grades of hydronephrosis and reflux; than patients recovered with STING only. Also these patients’ renal parenchymal thinning were significant and renal functions were worse than patients recovered with STING.

Conclusion: In our study, it was observed that the outcomes of surgical treatment were worse in renal units with high grade VUR, low differential function and secondary VUR etiology.
