    • Objective: Color Doppler ultrasonography provides a good way to study the incidence of paediatric renal diseases.
    Methods: 12080 children, aged 23 days to eighteen years-old, received color Doppler ultrasonography and high - frequency ultrasound scan (frequency 8.0MHz-13MHz) in the south-west region of China. Various renal diseases incidence was recorded.
    Results: The incidence of Renal hypoplasia was 0.12%, the higher in the male and the left kidney. The incidence of ploycystic renal disease was 0.19%, almost both sides. The incidence of extrarenal pelvis was 0.008%, the higher in the left kidney. The incidence of renal ectopia with renal hypoplasia was 0.0004%. The incidence of renal duplication was 0.37%, the higher in single side and right side. The incidence of agenesis of kidney was 0.0058%, single side was observed. The incidence of single hydronephrosis was 0.62%, the higher in male and right side. The incidence of renal cyst was 0.12%, the left side equal to the right side. The incidence of kidney stone without dropsy was 0.0058%. The incidence of hydronephrosis with kidney stone was 0.0041%, higher in right kidney, usually gently to midrange hydronephrosis. The incidence of caruncula papillaris coherence with caruncula papillaris was 0.12%.
    Conclusion: Congenital developmental anomaly was the common paediatric renal diseases. Kidney stone was rarely in children.
