METHOD OF DIFFERENTIAL DIAGNOSTICS OF CALYX DIVERTICULA AND SOLITARY RENAL CYSTS IN CHILDREN Russian patent published in 2011 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to nephrology and urology and is intended for differential diagnostics of calyx diverticula and solitary renal cysts in children. After carrying out water loading in amount 10 mg/kg of child body weight and intramuscular introduction of lasix in dose 0.6 mg/kg of child body weight, ultrasonic examination (USE) is performed 20 and 30 minutes after lasix introduction. In case, if after 20 minutes, during ultrasonic examination pelvis and cystic formation, which is not connected with kidney collector system, are visualised, and 30 minutes after lasix introduction during ultrasonic examination size of cystic formation does not increase in dynamics - solitary cyst is diagnosed. In case, if after 20 minutes after lasix introduction, during ultrasonic examination pelvis, cystic formation and dilatation of renal calyx neck are visualised, and 30 minutes after - increase of cystic formation dimensions and renal calyx neck diametre - calyx diverticulum is diagnosed.

EFFECT: method ensures possibility of carrying out differential diagnostics of solitary renal cysts and calyx diverticula, as a result of visualisation during ultrasonic scanning of calyx neck dilatation under conditions of water loading and forced diuresis.
