Introduction
A urinary creatinine level of 26.5 refers to 26.5 mmol/day, which is generally considered abnormal. Whether treatment is needed depends on the specific underlying cause. The normal range for adult urinary creatinine is 7–18 mmol/day; therefore, a value of 26.5 mmol/day is elevated. Urinary creatinine is primarily derived from the blood, filtered through the glomeruli, and then excreted from the body via urine.

1. No treatment required
The normal range for adult urinary creatinine is 7–18 mmol/day. A value of 26.5 mmol/day is relatively high. Urinary creatinine is primarily derived from blood filtered through the glomeruli and then excreted in urine. In some individuals, higher muscle mass, frequent meat consumption, or increased protein intake may lead to elevated blood creatinine levels, resulting in higher urinary creatinine after metabolism. Additionally, intense physical exercise can increase metabolic rate and glomerular filtration rate, causing a temporary rise in urinary creatinine. These transient elevations usually resolve with lifestyle modifications or rest and typically do not require special intervention.
2. Treatment required
Elevated urinary creatinine may be associated with conditions such as diabetic nephropathy or acromegaly. For diabetic nephropathy, common treatments include ACE inhibitors or ARB medications—such as captopril tablets or irbesartan tablets—to lower blood pressure and reduce proteinuria, along with antidiabetic drugs like metformin tablets. For acromegaly, surgery is the preferred treatment option, such as transnasal transsphenoidal resection of pituitary adenomas.
Measuring urinary creatinine alone has limited clinical significance in kidney assessment. It is recommended to undergo further examinations—including blood and urine routine tests, renal function tests, and renal ultrasound—to determine the underlying cause and receive appropriate treatment under medical supervision.
