The difference between horseshoe kidney and normal kidney is that the horseshoe kidney is two kidneys joined together, a congenital malformation of early embryonic development; while the normal kidneys are separated from each other. The location of horseshoe kidney is lower than that of normal kidney, usually above the pelvis and pelvic cavity; while the normal kidney should account for the range between 3-4 vertebrae, and also the ureter of horseshoe kidney is shorter than that of normal kidney, so it is easy to complicate urinary tract infection or abdominal mass, etc. Therefore, it is recommended that people with horseshoe kidney can be clearly diagnosed by retrograde pyelogram. Urinary tract infections should be avoided, usually you should drink more water, urinate more often, check routine blood and urine every 3-6 months, and review urinary ultrasound regularly. If co-infection is treated as early as possible to prevent disease progression and affect kidney function.
