Renal cysts are also called cystic kidney disease, and cysts can be classified as single, multiple fragments containing fluid or semi-solid. The most common clinical condition is simple renal cyst. Simple renal cysts are unilateral or bilateral kidneys with one or several cystic cavities of variable size that are not connected to the outside world and contain cystic fluid, and their incidence can increase with age. Because of the widespread clinical use of color ultrasound, such cysts can be detected in 50% of patients over 50 years of age. The general clinical manifestations of simple renal cysts are mainly as follows: 1. discomfort in the lower back and abdomen, or pain. 2. abdominal mass. 3. hematuria. 4. proteinuria. 5. hypertension in very few patients. What is the general clinical treatment for kidney cysts? According to the size of the cyst, below four centimeters can wait for observation; if it is more than four centimeters, it needs surgery. With the current medical condition, laparoscopic renal cyst decompression can be chosen, which usually takes one week for hospitalization.
