Urinary Screening for Early Detection of Kidney Diseases.

Objective: Urinary screening is a simple inexpensive tool to evaluate kidney functions. The authors carried out urinary screening of school children for early detection of kidney diseases.

Methods: Children in the age group 5-15 y were screened for urinalysis. They were divided in 2 groups; group-1 included 5-10 y and group-2 included >10-15 y old children.

Results: Urine samples of 3340(78%) out of 4283 enrolled children were tested. Abnormal samples were found in 5.75%; with proteinuria in 4.59%, pyuria in 3.29% and hematuria in 4.31%. Males constituted 47.71% in group-1 and 54.64% in group-2. Low body mass index was found in 94.1% group-1 and 78.99% group-2 children. Mild proteinuria was found in 1.2% group-1 and 2.56% group-2 children. Severe proteinuria was more in group-2 (0.77% vs. 0.06%) with female preponderance. Glucosuria was found in 1 boy of group-2. Urobilinogen was more in group-2 (0.65% vs. 0.24%) with male preponderance. Nitrituria was found in 9 girls. Pyuria (2.02% vs. 1.27%) and hematuria were more in group-2 (3.04% vs. 1.87%) with female preponderance. Combined proteinuria and hematuria (0.42% vs. 0.24%) as well bacteruria and fungaluria were more in group-2 (4.11% vs. 1.39%). Six of 192 children with abnormal urinary findings were treated; 1 for urinary calculus and 5 for urinary tract infection.

Conclusions: Abnormal urinary findings were more common in children >10 y of age. Thus urinary screening program of children can become useful for early detection of kidney diseases and contribute towards building up of a healthy nation.
