Abstract:
Introduction. Urolithiasis takes an important place in the structure of urological pathology,
thanks to its high incidence, its recurrence frequency and the complications it might cause. There
are many scientific publications dedicated to the study of urinary infection as an etiological
factor of urolithiasis. Chronic pyelonephritis has the important etiologic and pathogenic role in
the development of urolithiasis, but stone formation as a complication is possible in chronic
inflammation of the upper and lower urinary tract. In some cases, urinary infection precedes the
development of urolithiasis and may serve as a trigger for kidney stones formation. In other
cases, it associated with urolithiasis, arising from other infectious causes. The association of
metabolic factors and the infection usually forms chemically mixed renal stones containing
phosphates, which in most cases are recurrent. In general, urinary tract infection is detected in
80% of cases of urolithiasis.
