[0002] Renal puncture is a renal biopsy, also known as renal puncture biopsy. Due to the wide variety of kidney diseases and the complex causes and pathogenesis, the clinical manifestations of many kidney diseases are not completely consistent with the histological changes of the kidneys. For example, the clinical manifestations are nephrotic syndrome, and the pathology can be presented as microlesions, mild lesions, mild mesangial proliferation, membranous nephropathy, membranoproliferative nephritis, focal segmental sclerosis and other changes. The treatment plans and the development of the disease are also very different. The existing renal puncture generally uses a lumbar puncture needle as a guide to puncture the skin surface to open a channel to the kidney. After the channel is opened, a renal puncture needle is used to pierce the kidney to obtain the diseased tissue.
