Indications for operation and results from surgical treatment of vesicoureteral reflux

Abstract

The main objective of this retrospective study was to evaluate the value of surgical approach in the treatment of children with vesicoureteral reflux (VUR). Material and method: The study was conducted in the period from January 2006 to December 2014, and included children with symptomatic VUR, who were surgically treated. A total of 72 children were treated, of whom 56 were females and 16 were males, aged between 2 and 16 years. They were treated with IV and V grade reflux ureters. Thirty-two of the unilateral refluxes were left-sided, 18 right-sided and 22 both-sided. VUR was diagnosed with Voiding cystourethrography (VCUG). Cohen technique was performed in 64 (90%) patients, Politano-Lead better technique in 4 (5%) patients and Lich-Gregoir technique in 4 (5%) patients. Results: Out of the 72 treated patients, 69 had a postoperative negative finding of VUR on the performed VCUG, indicating a high 95% success rate. In three girls, persistent postoperative reflux was found in postoperative VCUG. In the first patient persistent VUR was unilateral, of V grade. In the second patient, a third-degree VUR was found and the third patient was diagnosed with II grade VUR. Postoperatively, non-febrile UTIs (urinary tract infections) were diagnosed in 23 patients (20 female children and 3 male children) out of 72 patients in total. One female child was hospitalized with febrile UTI and 8 patients or 10% developed febrile UTI within one year of the operative treatment. Conclusion: Open surgery, despite excellent results, is used for more complicated cases, VUR grade IV – V or in previously failed cases, and it does not appear to provide definitive correction of VUR in all patients and does not prevent certain low incidence of UTI postoperatively. Non-febrile UTIs can occur several years after a surgical correction. Endoscopic treatment is an alternative treatment for VUR.
