Why creatinine level increases in uti?

Number of reasons: Normally in a routine UTI, the creatinine should not be effected. If the UTI is completed and involves the kidneys, the creatinine level may increase due to kidney damage from the infection. Alternatively, some medications may cause an elevation. The creatinine may increase with a simple decrease in fluid consumption as well. ...Read more

Better to look at: Actual results rather than the ratio. What are the results for BUN and creatinine? Please note that all lab results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. ...Read more

Can UTI have a role in increased bun and creatinine?

Not usually : An uncomplicated, simple UTI (e.G, cystitis /bladder infection) would not affect your bun/creatinine/gfr which are the blood tests that reflect the overall function of the kidneys. A complicated, severe UTI affecting the kidneys (pyelonephritis) could, directly and or indirectly, affect kidney function and these blood tests if associated with sepsis, obstruction, or significant dehydration. ...Read more

Low bun/creatinine 5:1 and UTI symptoms. with out Uti. Could this be of concern?

Dr. Joseph Woods
Board Certified, Pathology

8M people helped

It depends,,,: It depends on the actual levels of BUN and Cr reported along with other lab values. If the Cr (Creatinine) is over 1.5 there might be cause for concern as it would point toward renal impairment, and there'd be other findings. Your other symptoms mentioned, flank pain, blood in urine, and proteinuria also point to a renal issue so see your doctor soon for more tests and treatment of the cause. ...Read more

Would getting a UTI cause the kidney numbers like egfr, bun, and creatinine to change for the worse?

UTI and EGFR: Normally, uti's have no effect on gfr. If you have some obstrction (o) in your urinary outflow tract, your GFR can decrease until the o is resolved. What was the time interval between your GFR readings? Call you doctor and get his advice or see a nephrologist for another opinion. Good luck. ...Read more

Cannot diagnose: This cannot be diagnosed long distance over the internet. You really should be seen by a doctor and fully evaluated. The elevation in creatinine may have been due to your state of hydration at the time of testing. Go and get seen. ...Read more

UTI + liver disease: You didn't mention painful frequent urination w/urgency, which are hallmarks of urinary tract infections (UTIs), whether simple cystitis (bladder) or pyelonephritis (kidney). Regardless, urine should be sent for culture & sensitivity so that doctor can confirm you've received appropriate antibiotic. Also need to monitor liver function given elevated AST & ALT, even test for infectious hepatitis ...Read more

I have high cretatine of 141.. Will disodium hydrogen citrate liquid for UTI infection increase level of cretatine?

Unclear: Are you referring to measurements of urine or blood? The creatinine in your blood is normally less than 1 mg/dl, and urine measurements will vary wildly according to the concentration of your urine. Either way, creatinine levels should not be affected by taking citrate (which acidifies the urine and helps clear bacterial bladder infections). ...Read more

Protein in urine: Protein in the urine may occur in setting of a UTI and blood ( as blood is protein). Protein that exists more than 3 months is more of an issue and needs to be followed more extensively. If persists beyond the urinary tract infection, needs to be quantitate do I.e. Determine how much protein is in the urine in mg/g of creatinine. ...Read more
