Abstract:
ObjectiveTo explore the efficacies of modified diamondshaped anastomosis for annular pancreas in newborns.To observe the differences of urine flow rate and postvoiding residual urine volume (PVR) in patients with enuresis in first desire to void (FD) and strong desire to void (SD) and provide rationales for examining urinary bladder function.MethodsFor 60 boys and 42 girls with primary nocturnal enuresis (PNE),urinary flow rate and PVR were measured respectively in FD and SD and the differences compared.ResultsThe maximum urine flow rate was （15.5±8.2）mL/s and PVR （2.9±5.9）mL in FD; The maximum urine flow rate was (19.9±9.7)mL/s and PVR (5.2±6.9)mL in SD; Statistically significant differences existed in maximum urinary flow rate and PVR (P<0.05).The maximum urine flow rate increased with rising voided volume,but the maximum urine flow rate decreased at a height of voided volume.No significant difference existed in maximum urine flow rate in FD among children of different genders.However,the maximum urine flow rate in SD of boys was significantly lower than that of girls (18.5±8.2 vs 24.2±12.5 mL/s,P<0.05).ConclusionUrine flow rate and PVR examination results are significantly different between FD and SD.Children with urinary incontinence should not retain excessive urination during free flow rate examination.And voided volume should be taken into account during the analyses of urine flow rate and PVR.
