Polycystic kidney is a genetic disease associated with mutations in the polycystic kidney disease gene (PKD), and is divided into infantile and adult forms, both of which are autosomal inherited diseases, with the infantile form being autosomal recessive and the adult form being autosomal dominant. Some patients have a combination of multiple cysts in the liver. Abnormal kidney metabolism, structural changes in the ducts and urinary tract infections may lead to kidney stone formation in polycystic kidney patients. Adult polycystic kidney patients may have pain in the abdomen or lower back, impairment of kidney function, and numerous cysts like blowing up balloons of different sizes that make the kidney significantly larger and can be felt as a mass in the abdomen. In combination with stones or infection, fever, hematuria and pusuria may occur. Some patients with hypertension may develop uremia when the kidney function is severely damaged. Polycystic kidney patients cannot be cured fundamentally, and the treatment focuses on delaying the damage of kidney function. Pay attention to rest, light diet and control hypertension in daily life. Urinary tract infections and stones blocking the urinary tract can aggravate the damage of kidney function. Therefore, timely control of infection and removal of stones blocking the urinary tract are important to protect kidney function.
