How long it takes for back pain to return to normal after kidney puncture varies from person to person, mainly related to the patient’s personal constitution, and cannot be generalized. Renal puncture biopsy is an important invasive diagnostic technique in nephrology, which can clarify the type of pathology and severity of the disease in order to guide treatment and assess prognosis. Patients need to lie flat in bed for 24 hours after the kidney puncture, and only after 24 hours can they get out of bed and try to rest as much as possible, and it usually takes about six months for the waist to return to normal. If the patient’s condition is more serious, accompanied by bleeding, edema, oliguria and other complications, they need to go to the regular hospital nephrology department for treatment in time, and the recovery time is longer. During the recovery period of kidney puncture, patients need to pay attention to prohibit strenuous physical labor and activities, as well as collision of the waist within 3 months. In daily life, it is recommended to drink more water, urinate more and pay attention to rest.
