Pelvicalyceal system’s dilation in children: classifications and management

Abstract

Dilation of the renal pelvis of the fetus is detected by antenatal ultrasound screening in 1–4% of pregnant women. In most cases, pyelectasia is transient, but it can be a sign of a wide range of obstructive and non-obstructive uropathies in a child after birth. To separate patients with physiological pelvicalyceal system dilation and patients requiring examination and treatment, clear criteria of norm and pathology are necessary. However, today there is a significant range of opinions regarding the definition of the norm, as well as the management of such patients, especially with a small and moderate pelvicalyceal system’s dilation. The review briefly highlights the main classifications of pelvicalyceal system’s dilation in children with an analysis of their advantages and limitations; provides recommendations from various authors on the timing and frequency of ultrasound and other studies after birth, the duration of observation of patients with antenatal pelvicalyceal system’s dilation, antibiotic prophylaxis of urinary tract infections and diagnostics of vesicoureteric reflux.
