Congenital horseshoe kidney must pay attention to whether there is abnormal kidney function, whether there is obstruction, stone formation and infection, mainly to observe whether there is hematuria, whether there is pain in the lower back, the thickness of the kidney cortex, etc. Congenital horseshoe kidney is mainly the lower pole of the two kidneys, in front of the abdominal aorta and inferior vena cava, fusing with each other to form a horseshoe-shaped malformation, the incidence of this condition is relatively low. The horseshoe kidney develops malformation, so the renal pelvis faces anteriorly while the renal calyces face posteriorly, and many blood vessels have variants. If there are no symptoms, observe regularly. If there is severe abdominal pain, back pain and poor digestive function, early surgery is performed.
