Бак посев мочи на инфекции мочевых путей (OYRON WELL D-ONE)

Laboratory screening for urinary tract and kidney infections is ordered to evaluate suspected or silent infections of the lower urinary tract—such as urethritis, cystitis, and ureteritis—and renal involvement including acute or chronic pyelonephritis and renal abscess. The workup also aims to identify the infectious agent and provide data to guide selection of antimicrobial therapy.

The kidneys and urinary tract form the excretory system, which maintains homeostasis by excreting metabolic waste, regulating water and electrolyte balance and acid–base status, contributing to endocrine functions, and participating in blood pressure control and erythropoiesis. The urinary outflow tract comprises the calyces, renal pelvis, ureters, bladder, and urethra. Initial laboratory assessment of suspected infection relies on urinalysis, microscopic examination of the urinary sediment, and urine culture to verify the pathogen. A two‑portion (two‑glass) urine collection may help localize inflammation: abnormalities in the first fraction suggest urethral involvement, whereas changes predominating in the second fraction indicate disease of the upper urethra or bladder consistent with urethritis or cystitis. In men, abnormalities confined to the second portion may reflect prostatitis or seminal vesiculitis. Broader patterns of abnormal findings can point to disease of the ureters or kidneys, aligning with ureteritis or pyelonephritis.
