야뇨증은 소아뿐만 아니라 부모들에게 매우 애를 먹이는 현상이며, 때로는 정신적, 정서적 장애 또는 행동장애를 유발할 수도 있다. 적절한 치료를 하기 위하여서는 세심한 병력, 신체검사와 필요에 따라서 적절한 실험실 검사 및 방사선검사으로 단인증상성 야뇨증인지를 제대로 구별하여야 한다. 실제 임상에서 야뇨증의 치료는 그렇게 용이하지만은 않아 우선 어린이와 부모들이 야뇨증을 제대로 이해할 수 있도록 사전 교육을 통하여 적극적인 치료 의지를 갖도록 하는 것이 중요하다. 여러 가지 행동요법 및 야뇨경보기, 적절한 약물요법을 환자의 상황에 맞도록 적절한 치료 방법을 모색하여 보다 치료 효과가 높고 재발이 적도록 노력하여야 한다.

The purpose of this study was to survey guardian's opinion on assisting pediatric radiography and their level of awareness of radiation, improving the quality of pediatric radiography. In this study, the recognition was analyzed for 210 parents of child patients in Pusan National University Hospital from August 20 to September 15, 2013. A total of 66.2 percent of the respondents said they had participated in pediatric radiography in the past. The reason why they did is "Radiologist's request", the highest. According to the survey, 84.3 percent said they thought it is necessary to attending patient in pediatric radiography. "The stability of the child" is the reason for it. And respondents who thought there's no need to do that answered back, the reason for this is "Radiologist's work." There was a significant difference on the psychological state for the medical radiation by gender and child age. (p<0.05) In the analysis of recognition for the radiation, there was the significance by gender and education. (p<0.05) Regarding the awareness of the radiation protector, there was a statistical significance in age, gender, child age and education. (p<0.05) Considering the results, pediatric patient's guardians recognized that it is necessary to attend a child on X-ray for their child's stability and accurate exam above all. It must make guardians wear X-ray protector and radiologist should let the guardians recognize the X-ray examination method, before starting pediatric x-ray. It needs to improve the atmosphere of the examination room and to be considered to take visual and auditory approaches in comfort for reducing the children's fear and anxiety.

Even though children are exposed to the same amount of radiation, their effective dose amount is higher than those of adults. Therefore, it is very important to reduce the amount of unnecessary radiation exposure because children have a higher radiosensitivity and a smaller body size than adults. In this study, the proposal to seek ways to reduce the amount of radiation is drawn by comparing and analyzing CT Dose Index(CTDI) on the pediatric head CT which was performed at the Busan regional hospitals, to the national diagnostic reference levels. For this, the pediatric head CT scan was conducted among the CT equipments that were installed in downtown Busan. From 2,043 children 10 years old or less who were referred to the pediatric head CT scan, targeting the 28 CT equipments in the 24 hospitals that transmit dose reports to PACS, were examined retrospectively. As a result, the average value of CTDIvol, computed tomography dose index (CTDI) of infant brain, across the hospital, was 31.18 mGy, with DLP of $444.73mGy{\cdot}cm$, which exceeded the diagnostic reference level. The lower the age, the more management is needed for radiation. However, the reality is that the CT examinations are being conducted with a dose that exceeds the reference level as the age of the aged is exceeded. For this purpose, the study seeks to determine the degree of doses of doses outside the diagnostic reference level and analyze the cause of the excess dose and devise measures to reduce the dose reduction.

Since in case of children, they are sensitive to the radiation compared to the adult and the potential exposure damage lasts longer, the exposure dose should be managed better than for the adult. Therefore, this study was conducted to observe the change in the chest x-ray image by the use of grid, which eliminates the scattering rays but increases the exposure dose during the child chest x-ray examination. As a research method, SNR, CNR and V. Vuichi were measured at 100 cm and 180 cm with the grid varying the kVp to 70, 90 and 110. In addition, SNR, CNR and V. Vuichi were measured fixing 100 cm and 180cm without grid and varying the dose to 6, 8 and 10 mAs. In the results of measuring them by fixing kVp, SNR, VNR and V. Vuichi were represented high when FID is 100cm. And in the results of meaduring them varying mAs, SNR, VNR and V. Vuichi were represented high when FID is 100cm. Currently in our country, the chest x-ray examination is performed at 180 cm. However, as the image is measured high when FID is 100 cm, in case of child, FID is deemed to be 100 cm.

Purpose : We attempted to compare the independent factors such as age, sex, C-reactive protein(CRP), and white blood cell count(WBC) in children with radiologic studies and assess the necessity of performing voiding cystourethrography(VCUG). Method : 98 children who have been diagnosed their first time febrile urinary tract infection from Janurary 2002 to Januray 2005 were enrolled. In all patient, the duration of fever which occurred before and after treatment was recorded, and CRP, WBC, $^{99m}Tc$-2,3-dimercaptosuccinic acid($^{99m}Tc$-DMSA) renal scans, renal ultrasound and VCUG were analyzed. Results : Of the 98 children diagnosed with urinary tract infection(UTI), 52 were male and 46 were female. 18 had abnormalities in VCUG, 17 had abnormalities in kidney ultrasound, and 20 had partial defects or diffuse uptake decrease in $^{99m}Tc$-DMSA renal scans. There were no significant relationship between incidence of radiologic abnormalities and age. The risk of renal scar was significantly higher in children who had a longer febrile period before treatment than in those with shorter period. Both CRP and WBC were significantly elevated in children with the radiological abnormalities. A positive of $^{99m}Tc$-DMSA renal scans and renal ultrasound were highly associated with vesicoureteral reflux(VUR). Conclusion : If there are abnormalities in the kidney ultrasound and $^{99m}Tc$-DMSA renal scan of a child with initial UTI, a VCUG is recommended. Even in cases without abnormal findings in $^{99m}Tc$-DMSA renal scan and renal ultrasound, clinical data such as CRP and WBC should be assessed, and VCUG should be Performed for the undetected VUR.

In this study, we investigated utility of ultrasonography for urinary tract infections of infants. The results of the research is as follows : 1. The number of infants under one year old was 100 out of 122 infants who were diagnosed as a unitary infection. The ratio of males to females was 1.7 : 1. Seventy-seven infants who underwent three kinds of radiologic examinations such as kidney sonography (51%), $^{99m}TC$ DMSA-scan (42%), and VCUG (22%). 2. In comparison of correlation between kidney sonography and VCUG, the sensitivity of kidney sonography was 82% while the specificity of kidney sonography was 58%. In comparison of correlation between kidney sonography and $^{99m}TC$ DMSA-scan, the sensitivity of kidney sonography was 66% while the specificity of kidney sonography was 67%. 3. Utility of kidney sonography showed the highest efficiency when we considered pain, discomfort, a sense of shame, psychological stress when infants may undergo at the examination, side-effect of a contrast agent after the examination, and complication of exposure to radiation.
