Precautions for kidney cyst puncture: First, before kidney cyst puncture, we should pay attention to exclude any contraindications to kidney cyst puncture, for example, if the patient has a serious bleeding tendency, we cannot perform kidney cyst puncture, so we should improve blood routine, coagulation function and other related tests before the operation. Secondly, in the process of renal cyst puncture, when performing renal cyst puncture under ultrasound guidance, patients should be told to pay attention to cooperate with the doctor’s command, if patients do not cooperate properly or appear to move around, they may accidentally puncture other organs or cause bleeding from the kidney puncture. Thirdly, we should pay attention to the color of urine, blood pressure and other related conditions of patients after kidney cyst puncture, and pay attention to any complications after kidney cyst puncture, such as bleeding and infection.
