Urine is collected over variable time periods, and the concentration measured reflects an average for the time involved (Cefazolin and ceftriaxone achieve very high urine concentrations; hence, subtherapeutic concentrations with renal insufficiency is unlikely.

Roughly 5% of filtered drug is reabsorbed by the cells of the proximal renal tubules (Aminoglycosides are not indicated for the treatment of cystitis or urethritis.

Cystoscopy allows your doctor to view your lower urinary tract to look for abnormalities in the urethra and bladder. Infections of the urethra are viewed as superficial, whereas pyelonephritis is considered a parenchymal infection.
Antimicrobial treatment of UTI requires adequate serum, renal, parenchymal, and urine concentrations of drugs with antibacterial activity There are more than 7 million uncomplicated urinary tract infections (UTI) per year in the United States (The management of UTI in patients with chronic renal insufficiency has attracted little to no attention. There is no need to add sulfamethoxazole as the patients with low creatinine clearances will likely have subtherapeutic urine concentrations.
This subject deserves more attention.Published online ahead of print.
Analyzing a sample of your urine (urinalysis) may reveal abnormalities that suggest kidney failure.
