Abstract

Objectives. This study aimed to demonstrate if the addition of anti-inflammatory treatment to antibiotic therapy shows any superiority to the treatment with antibiotic only. Methods. Forty-nine Wistar rats were divided into 7 groups. Pyelonephritis was performed by E. coli injection to upper pole of kidneys except control group. Group 2 was not treated. Ceftriaxone, ketoprofen, "ceftriaxone + ketoprofen," methylprednisolone, and "ceftriaxone + methylprednisolone" were given in the groups. The technetium-99m-dimercaptosuccinic acid scintigraphies were performed in 3rd day to detect pyelonephritis and 10th week to detect renal scarring. All kidneys were also histopathologically evaluated. Results. When 3rd day and 10th week scintigraphies were compared, initial 2.00 +/- 0.30 point pyelonephritis score resulted in 0.71 +/- 0.36 renal scar score in "ceftriaxone + ketoprofen" group (P - 0.039). Initial 2.00 +/- 0.43 point pyelonephritis score resulted in 0.86 +/- 0.26 renal scar score in "ceftriaxone + methylprednisolone" group (p = 0.041). Renal scar score was declined in "ceftriaxone + ketoprofen" group and "ceftriaxone + methylprednisolone" group compared with no-treatment group on 10th week of the study (P = 0.026, P = 0.044). On histopathological evaluation, it was seen that renal scar prevalence and expansion declined significantly in "ceftriaxone + ketoprofen and "ceftriaxone + methylprednisolone" (P = 0.011, P = 0.023). Conclusion. It was evidenced that ceftriaxone treatment in combination with ketoprofen or methylprednisolone declined scar formation in scintigraphic and histopathologic examinations of the kidneys.
