Clinical manifestations such as asthenia, dysuric disorders, pain in the abdomen and lower back, with bilateral changes in the calyx-pelvic system, occur 2-4 times more often than with unilateral ones. The degree of impairment of the outflow of urine from the kidneys also clearly affects the frequency of asthenia, abdominal pain, dysuric and dyspeptic disorders. With pyelonephritis, the excretion of ammonia decreases and the release of oxalates, uric acid, calcium, phosphorus increases in proportion to the severity of changes in the pyelocaliceal system.</p>Kazan Medical archiveКазанский медицинский архив
