How to do kidney biopsy

Renal biopsy is a routine examination in the nephrology department. It plays a very important role in clarifying the pathological type of kidney disease, formulating treatment plans, and judging the prognosis. Before kidney puncture, the blood coagulation function, platelet condition, and blood pressure of the human body must be evaluated first, so that the blood pressure is less than 160/80mmHg to avoid possible bleeding during the puncture process. At present, puncture is performed under the guidance of color Doppler ultrasound, so related complications will be avoided, that is, no major complications such as damage to surrounding tissues, organs, and nerves will occur. Under the color Doppler ultrasound, the puncture needle can clearly see the shape of the human body. When the puncture needle reaches the kidney, a piece of kidney tissue about 1.5cm-1.8cm in length can be taken out and sent for pathological examination. After the puncture, the local puncture point is compressed and the patient is instructed to lie supine on the bed for 24 hours, especially during the first 6 hours, to be absolutely in bed, not to turn over, let alone to sit up, and avoid strenuous activities for 1 month after the puncture.
