A high granular tubular pattern usually means that the urine contains more epithelial cell debris, plasma proteins, and other tangible material and is seen in a variety of kidney diseases.
Renal tubules are usually made up of a combination of protoplasm from shed epithelial cells. In normal individuals, granular tubules are sometimes seen in the urine, usually after strenuous exercise. However, if granular tubular pattern often appears in urine with high values, it is generally considered to be related to kidney diseases, such as chronic glomerulonephritis, pyelonephritis, interstitial nephritis, and various kinds of renal tubular injuries.
If you find high granulomatous tubular pattern in urine, it is recommended to go to regular hospitals for timely consultation, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
