    Abstract:
    OBJECTIVE: Spina bifida occulta (SBO) has been largely considered a benign entity without clinical significance; however, there has been dispute among various authorities, and some believe that the lesion may be linked with various neurologic conditions like urologic dysfunctions. Vesicoureteral reflux (VUR) and lower urinary tract dysfunction are closely related. We examined whether the existence of SBO is related to the prevalence and severity of VUR in children. METHODS: We investigated 359 children, 2-14 years old, referred to radiology department for obtaining voiding cystourethrogram after the first attack of febrile urinary tract infection. After treatment of infection, with written order of responsible physicians all underwent a standard voiding cystourethrogram to detect VUR and other lower urinary tract anomalies. The patients were divided into two groups: group1 patients who had not SBO and group 2 patients with SBO in postvoiding or KUB films. In each group the presence and severity of VUR was determined in relation to the location of SBO. FINDINGS: Out of 359 children, 228 (63.5%) had normal spine and 131 (36.5%) had SBO. Fifty four (23.7%) out of 228 children with normal spine had VUR and 40 (30.5%) out of 131 children with SBO had VUR. The prevalence of VUR in children without SBO and children with SBO was not statistically different. Also we compared the severity of VUR between the two groups and there was no significant difference or trend between presence of SBO and severity of reflux (Chi(2) for trend). VUR was more common in children with SBO in L5-S1 (38.3%). There was no significant relation between location of SBO and prevalence of VUR. CONCLUSION: Location of SBO and prevalence of VUR are not related.
