ABSTRACT

Decrease in voiding frequency in children lead to improve the capacity of bladder which tends to reduce the intake of fluid as the child relies on table food for nutrition. The objective of the study was done to enumerate the clinical features of voiding dysfunction in children and correlate the clinical findings with uroflow electromyography (EMG) findings. A prospective clinical research conducted on children of 5-18 years old with the inclusion criteria of children attained bladder control, no complaints of infection of urinary tract and normal neurological status. A sum of 20 children were taken for this study. While the child was passing urine; rate of flow, amount of urine voided, peak flow rate and time to void were recorded. Shape of the curve obtained as uroflow was also studied. Sphincter activity was noted by uroflow electromyography machine. The uroflow electromyography testing in 17 children (85 %) of 20 was abnormal. The various abnormalities included staccato voiding, fractionated voiding and sphincteric contraction during the voiding phase. In 11 children with history of prior urinary tract infection (UTI), 8 exhibited abnormal voiding on uroflow electromyography. Increased frequency as symptom was noted in 16 children with abnormal uroflow electromyography findings. Fourteen children who were unable to control the urge to void exhibited abnormalities on their uroflow electromyography. Uroflow electromyography to be a useful tool in the management of children with voiding dysfunction as it helped in the identification of the exact nature of the problem on an objective basis.
