Abstract:
Objective:To investigate the clinical characteristics of urinary system abnormalities in Chongqing and its surrounding area, and to assess the role of the large-scale urinary system ultrasound screening in the asymptomatic children with kidney and urinary tract abnormalities. Methods:We performed urinary system ultrasound on Screening 14 256 children from September 2008 to October 2008 in Chongqing Children’s Hospital. The total samples were allocated into five groups as follows:less than 1 year group;1 to 3 years group;3 to 5 years group;5 to 10 years group ;more than 10 years group. Then according to each group’s age,sex,disease location,severity difference,we performed statistical analysis. Results:409(2.87%)of 14 256 children had abnormalities,284 of whom was diagnosed with significant anomalies,including hydronephrosis,renal maldevepment (aplastic,dysplastic,hypoplastic,ectopic kidneys)and renal agensis,nephrolithiasis,simple renal cyst,multicystic dysplastic kidneys (MCKD),ureter dilation,duplex kidneys and so on. Among these anomalies,the most prevalent abnormal finding was hydronephrosis accounting for 130 cases,almost a half of 284 (45.77%),92 cases in males,38 cases in femal. The prevalence of melamine related urinary calculus was as 5.17 times as that of others and its 95% confidence interval(CI)of population relative risk was [3.28,8.14]. Conclusion:① Ultrasonography in the diagnosis of diseases of the urinary system can play an important role,especially for congenial anomalies of kidney and urinary tract(CAKUT)and /or hydronephrosis and so on. Therefore,an early diagnosis of these defects allows to realize as fast as possible the best medical and/or surgical treatment, preventing or at least slowing down the progression to chronic renal failure. ② The prevalence rate of hydronephrosis in male is higher than female. ③Exposure to melamine- contaminated formula is associated with urinary stones.
