High urinary tubular count is generally suggestive of kidney disease, which can be clinically seen in acute pyelonephritis, chronic pyelonephritis, acute interstitial nephritis, chronic interstitial nephritis and vasculitis, lupus and other diseases. It is recommended to further investigate blood routine, urine routine, 24-hour urine protein quantification, rheumatoid immunity and other related examinations to clarify the diagnosis. If the increase in tubular number is caused by urinary tract infection, it can disappear by drinking more water, urinating more often and applying antibiotics for 14 days. If it is caused by interstitial nephritis, it is recommended to avoid the application of nephrotoxic drugs, while acute interstitial nephritis can be treated with hormones; if it is caused by chronic interstitial nephritis, it needs kidney preservation treatment; if it is caused by vasculitis and lupus, it needs active anti-immune treatment.
