Is the Grade of Vesicoureteral Reflux Related with Detrusor Overactivity?

Aim: The videourodynamic study outcomes in patients with vesicoureteral reflux were retrospectively reviewed. The aim of this study is to evaluate the relationship between the idiopathic detrusor overactivity and the grade of vesicoureteral reflux. Material and Method: We reviewed retrospectively the videourodynamic traces of 71 vesicoureteral reflux patients without neuropathic conditions. Patients were divided into two groups: Patients without concomitant detrusor overactivity (Group 1), and patients with concomitant detrusor overactivity (Group 2). The reflux grades were divided into two grades; low-grade reflux (grades 1 and 2), high-grade reflux (grades 3, 4 and 5). Data were analyzed using the chi-square test. Results: Patients ages ranged between 5 and 16 years (mean 8.37±2.97 years). Of the 71 patients, 39 (54.9%) had a normal detrusor activity (Group 1), 32 (45.1%) had a detrusor overactivity (Group 2). Twenty-five (64.1%) patients in-group 1 had a low-grade reflux, 14 (35.9%) patients had a high-grade reflux. In-group 2, 17 (53.1%) patients had a low-grade reflux, 15 (46.9%) patients had a high-grade reflux. There was no significant difference between the two groups (p=0.488). Discussion: The idiopathic detrusor overactivity can be observed during urodynamic investigation of patients with vesicoureteral reflux, but it has no effect on the grade of reflux
