After renal puncture, first of all, we should pay attention to observe the size of hematoma, pay attention to observe the urine color, blood pressure and so on, and check whether the hematoma has been enlarged on time. Secondly, bed rest should be taken to avoid hematoma enlargement. Most of the hematoma caused by renal puncture is due to the damage of surrounding small blood vessels, which is unavoidable in invasive examination and more common in clinic. The incidence of ultrasound monitoring after puncture can be up to 85%, but most of these hematomas are small hematomas with no special symptoms, most of which can be absorbed, and larger hematomas need to be closely monitored for changes in the size of the hematoma, and pay attention to the observation of the urine color, blood pressure, etc. If there is no significant increase in size and no new cases, you should stay in bed to avoid the increase in hematoma size. If there is no obvious increase and no new hematuria, normal life can be taken care of, but can not be tired, can not lift heavy objects, to avoid coughing and other exercises to increase abdominal pressure. If there is hematoma on the basis of hematoma with hematuria, it is recommended to bed rest until the disappearance of hematuria, and if the blood pressure drops, surgery is needed, so be sure to follow the doctor’s instructions for regular review.
