The duplex kidney assosiated with obstructive uropathy of the upper and lower segments is a condition difficult to manage in pediatric urology. Embryological predisposition determines a number of significant functional and urodynamic disorders that are common in children at the age of 3 years. That decrease the quality of children’s lives, especially under 3 years old. The article presents a clinical case of a 3-month girl. The 20-week antenatal ultrasound scan showed a duplication of the right kidney with megaureter of both segments without critical dilation. The leukocyturia was detected after birth. The child was admitted to the surgical hospital. Nephrostomy tubes were inserted in the duplex kidney due to severe purulent pyelonephritis. The girl was diagnosed with hydronephrosis of the lower segment with a decreased function by 52%, non-refluxing megaureter of the upper segment with absence of upper half kidney function. Pyeloplastic of the lower half of the ureter was performed. Epigeminefroureterectomy of the upper half of the kidney was performed at 6 months. In conclusion, duplex kidney assosiated with obstructive uropathy requires timely diagnosis and patient follow-up.
