Question
How to treat left ureteral hydronephrosis in children?
Answer
Ultrasound shows renal hydronephrosis on the left kidney, with thickened walls in the upper and middle segments of the ureter and roughened inner walls in the lower segment. Further examination may be needed to confirm the cause, and treatment should be coordinated with a doctor, including possible medical decompression and adjustment of hygiene habits, as well as reasonable dietary management to avoid irritating or cold foods.
