Why should kidney disease do kidney puncture needle examination?

It is a valuable laboratory test for clinical diagnosis of renal diseases. Many kidney disease symptoms, prognosis, treatment is also different, but the clinical manifestation is similar, such as performance for proteinuria and hematuria, so it is difficult to determine based on clinical tests and general inspection alone diagnosis, for clinical doctors targeted treatment measures in time, because this often needs to make inspection of renal biopsy. In the diagnosis of renal diseases, renal puncture has the following significance :(1) to determine the etiology, such as primary glomerular disease or secondary glomerular disease, through renal puncture, which is common in lupus nephritis, vasculitis-associated nephritis and diabetic nephropathy; (2) To clarify the pathological type and understand the degree of kidney damage can provide a basis for doctors to judge the prognosis of patients according to the scope and degree of pathological damage. (3) To guide the treatment of patients with hematuria, for example, if renal puncture shows only mild mesangial cell hyperplasia, the patient may only need general symptomatic treatment with a good prognosis. For crescent nephritis, the doctor may consider using a larger dose of immunosuppressive agents for treatment. For example, for a patient with sudden hypouria, sometimes it is difficult to determine the cause of the disease clinically, and the deterioration of renal function is rapid. In order to make a timely diagnosis, doctors need to do renal puncture examination immediately, because it is of great significance for doctors to choose medical plans. Kidney puncture is a complicated examination with high technical content, which generally needs to be performed in a tertiary hospital or with the cooperation of physicians specializing in kidney and pathology. Whether to carry out renal pathological examination is also a sign to measure the level of diagnosis and treatment of renal diseases in hospitals.
