ABSTRACT
Objective@#To explore the effect of bladder overdistention on uroflowmetry and post-void residual urine(PVR)in children with primary nocturnal enuresis (PNE).@*Methods@#A total of 136 children with PNE from March 2015 to June 2018 at Department of Pediatric Urodynamic Center, the First Affiliated Hospital of Zhengzhou University were enrolled, aged 5-14 years, with mean age of (7.96±2.48) years old.Uroflowmetry and PVR measurement were performed in the condition of over and no urinary distention, respectively.According to the initial urinary voided volume (VV), the children were divided into 3 groups, 25 mL≤ VV<50 mL(group 1), 50 mL≤VV<100 mL(group 2), and VV≥100 mL(group 3). The VV, maximum flow rate (Qmax), average flow rate (Qave), urine flow time, and PVR were compared interms of condition between the groups.Different types of flow curve were analyzed simultaneously.@*Results@#In the condition of bladder over distention, the VV, Qmax, Qave, urinary flow time and PVR of children were higher than those with no overdistention[group 1 (168.25±103.23) mL vs.(34.04±7.03) mL, (17.76±11.13)mL/s vs.(8.23±2.72) mL/s, (9.56±4.13) mL/s vs.(4.30±1.55) mL/s, (20.24±15.13) s vs.(8.64±4.27) s, (3.90±3.55) mL vs.(1.50±2.55) mL; group 2 (168.65±80.66) mL vs.(68.04±15.13) mL, (16.41±5.18) mL/s vs.(14.61±5.29) mL/s, (9.86±3.56) mL/s vs.(8.14±2.29) mL/s, (18.75±10.73) s vs.(9.41±3.47) s, (5.98±8.59) mL vs.(2.77±6.41) mL; group 3 (280.24±102.00) mL vs.(181.50±66.22) mL, (22.73±8.21) mL/s vs.(20.42±6.25) mL/s, (12.57±3.68) mL/s vs.(11.00±3.22) mL/s, (23.46±10.65) s vs.(17.01±6.90) s, (3.78±6.26) mL vs.(2.09±3.21) mL], and the differences were all significant(all P<0.05). Excluding physiological pseudomorphism, urinary flow curves of 114 children with initial urinary intention and excessive voiding were obtained.The incidence of Staccato urinary flow curve was significantly higher than that with no distention [6.14%(7/114 cases) vs.21.93%(25/114 cases), χ2=14.45, P<0.05].@*Conclusions@#Bladder overdistention induced significant influence on the uroflowmetry and PVR.
