Kidney tubule injury may lead to elevated creatinine.
Renal tubules are the components of renal units, which are mainly responsible for reabsorbing water, some nutrients, and secreting some metabolic wastes.
If there is serious injury or even obstruction, it may lead to elevated creatinine, such as drug nephropathy, toxic tubular injury, interstitial nephropathy and so on. At this time, the main manifestations are decreased urine specific gravity and increased creatinine, while there is no protein or only a small amount of protein in the urine. If the renal tubular injury is mild, it can not show creatinine elevation.
Since the epithelial cells of renal tubules can be regenerated, most of the renal tubular injuries, especially acute tubular injuries, can be completely restored to normal after active treatment.
Patients with renal tubular injury, especially those with elevated creatinine, must complete the relevant examinations under the guidance of doctors in specialized hospitals to clarify the cause of the disease and then carry out targeted treatment. Do not use your own medicine, especially do not easily apply all kinds of secret prescriptions, so as not to aggravate kidney injury.
