Introduction:

Ultrasound (US) is a noninvasive technique without ionizing radiation; ability to perform the examination with a portable device is also notable. These features make US the primary tool for renal imaging. Renal structural abnormalities may be asymptomatic during childhood and adolescence. We present our preliminary findings obtained during the evaluation of healthy school children and adolescents.

Material and methods:

The study group, representative of the socio-economic status of the population, consisted of 6-18 years old school children (849 volunteers; mean age 12.1 ± 3.5 years; 52.1% female). After informed consent was obtained from parents and participants without known medical disorders, US examinations were performed by a radiologist with a portable device at schools. 

Results:

Renal and extarenal abnormalities were detected in 17 (2.0%; 95%CI 1.2-3.2%) and 35 children (4.1%; 95% CI 2.9-5.7), respectively. Renal abnormalities were as follows: horseshoe kidney (n= 2); ectopic kidney (n= 1), malrotation (n= 1), renal calculi (n= 5), renal cyst (n= 4), hydronephrosis (n: 3), and a solid lesion (n: 1). All cases with renal calculi were above 12 years of age. The frequency of renal abnormalities was comparable for both sex. Extrarenal lesions were fatty liver (n= 19), hepatic cysts (n= 2), ovarian cysts (n= 9; all cases were above 12 years of age), splenomegaly (n= 3), biliary calculus (n= 1), and prostatic utricule (n= 1). The presence of fatty liver was associated with increased body mass index (p<0.001).

Conclusions:

Renal abnormalities were detected in 2% of apparently healthy 6-18 years aged children and adolescents. Early detection of abnormalities with renal US may be beneficial for timely evaluation and management, preventive measures, and a better outcome.
