RESUMO
This study aimed to evaluate the efficacy and safety of oral antibacterial treatment with fluoroquinilone for acute uncomplicated pyelonephritis Thirteen female patients with acute uncomplicated pyelonephritis were treated with oral fluoroquinilone (ciprofloxacin; CPFX). They received 200 mg of the drug three times a day while febrile (3-5 days). Once they become afebrile, the same dose of the drug, given twice a day, was given for another 9-11 days. The mean duration of the course of CPFX was 14 days. Symptoms were evaluated, and laboratory examinations, including urine culture and measurement of the minimal inhibitory concentration (MIC) of CPFX were conducted before treatment, and 3, 7, 14, 21, and/or 28 days after the initiation of the treatment. Of the 13 patients, only 5 needed to be hospitalized, and the period of hospitalization was only a few days. On the 14th day after the commencement of treatment, bacteriologic and clinical cure rates were 100%. Escherichia coli was the most common uropathogen, being isolated from the urine of 8 patients. No clinical relapse of the disease was found during a follow-up period of up to 4 weeks. The patients tolerated the drug well without developing any serious adverse effects. Oral antimicrobial chemotherapy with fluoroquinolone, given on an outpatient or short-term hospitalization basis, achieved satisfactory bacteriological and clinical outcomes in the treatment of acute uncomplicated pyelonephritis. This treatment regimen is indicated for patients with this disease who are not in a serious condition with complications such as shock.
