- Abstract:
- Objective To evaluate the lower urinary tract dysfunction (LUTD) in children with vesicoureteral reflux (VUR) without neurological or lower urinary tract organic lesions by urodynamic examination.Methods From January 2017 to December 2021,the results of UDS examination were retrospectively reviewed for 106 VUR children.According to the presence or absence of LUTD,they were divided into LUTD group (n=77) and non-LUTD group (n=29).Such urodynamic parameters as bladder volume,residual urine volume (PVR) and maximum urine flow rate were compared between two groups.Results Residual urine volume was significantly higher in LUTD group than that in non-LUTD group (t=5.564,P=0.008).And maximum urine flow rate was lower than that in non-LUTD group (t=6.314,P=0.030).Among LUTD children,29 cases were of low grade VUR (grades Ⅰ-Ⅲ) and 48 cases high grade VUR (grades Ⅳ-Ⅴ).Bladder compliance (χ2=7.537,P=0.006) and PVR (χ2=4.298,P=0.038) were significantly different between low-grade VUR and high-grade VUR.Idiopathic detrusor overactivity disorder (IDOD) was the more common type of LUTD 45.5%(35/77) and 65.5%(19/29) in low-grade VUR.Dysfunctional voiding (DV) was more common in high-grade VUR 56.2%(27/48).Conclusion Higher PVR and lower maximum urine flow rate hint at a greater possibility of LUTD in VUR children.Children with high-grade VUR are more likely to have a greater increase in PVR and a poor bladder compliance.IDOD is common in low-level VUR while DV is more common in high-level VUR.
