A horseshoe kidney is a congenital condition where the two kidneys are fused together at their lower ends, forming a U-shape that resembles a horseshoe. This fusion typically occurs during fetal development and affects about 1 in 500 people. While many individuals with this condition may not experience symptoms, it can sometimes lead to complications such as urinary tract infections or kidney stones. Diagnosis of a horseshoe kidney is often made through imaging tests like ultrasound or CT scans. Treatment is usually not necessary unless complications arise. Regular monitoring and maintaining kidney health are important for those with this condition.
