The hospital stay for kidney puncture takes about 5-7 days, although it is a minimally invasive operation and does not take long, about half an hour to complete the kidney puncture, but some relevant tests must be completed before the kidney puncture to clarify whether there are any contraindications to kidney puncture. After the procedure, the patient should be observed for any complications of the kidney puncture, so the hospital stay is relatively long. Some of the preoperative tests that need to be completed include blood routine, coagulation function, liver and kidney function, and urological ultrasound, etc. Blood pressure should also be closely monitored, and renal puncture is not recommended for patients with isolated kidney, hypertension that is difficult to control, or obvious bleeding tendency. After kidney puncture, the patient’s blood pressure and heart rate should be closely monitored, and the patient should be concerned about persistent hematuria.
