Causes of Acute Pyelonephritis

Abstract

Acute pyelonephritis is one of the most common infectious and inflammatory diseases of the kidneys and occupies a significant place in the structure of urological disorders.The aim of the study was to analyze 104 medical records of patients 2024-2025.Among the patients, women predominated — 75 (72.1%), while men accounted for 29 (27.9%). The bilateral form of the disease was most frequently observed — 63 cases (60.6%). Unilateral pyelonephritis was diagnosed in 27 patients (25.9%). In 7 cases (6.7%), the disease developed during pregnancy. The obtained results indicate a high prevalence of this disease among the working-age population, which negatively affects patients’ quality of life and increases the burden on the healthcare system. The analysis of clinical data demonstrated that the course of acute pyelonephritis largely depends on the timeliness of seeking medical care, as well as the presence of associated risk factors. It was found that early diagnosis combined with appropriate treatment reduces the likelihood of complications and prevents the progression of the disease into a chronic form. Therefore, particular attention should be paid to preventive measures aimed at eliminating predisposing factors.
