Usually, most kidney stones and hydronephrosis can be cured after active treatment and will not affect normal life expectancy. Kidney stones and hydronephrosis are one of the common lesions in the urinary tract, mainly related to daily life and dietary habits, mostly seen in people who drink less water, exercise less, like high-fat and greasy food, high sugar food, etc. The clinical manifestations are dull pain in the kidney area, frequent urination, painful urination, hematuria and other symptoms. Once the symptoms appear, you need to go to the urology department as early as possible to get a clear diagnosis through urological ultrasound, CT and other examination items. At present, stones can be crushed and removed through minimally invasive surgery such as ureteroscopy or percutaneous nephrolithoscopy. After the surgery, kidney-protective drugs and diuretic drugs should be actively used to promote the recovery of kidney function, which usually will not affect the normal life span. If the treatment is not timely, leading to the appearance of kidney failure, treatment is difficult and survival time will be affected. Therefore, it is recommended to have regular medical checkups at regular intervals to detect problems and treat them early.
