Purpose: Urinary tract infection (UTI) is one of the important infectious diseases of childhood age. It causes serious late-term complications by leading to development of renal scarring in some pediatric patients. In the present study, it was aimed to determine the risk factors in development of renal damage in the pediatric patients that admitted with clinical of acute pyelonephritis. Materials and methods: In our study, the medical files of the patients were admitted to the pediatric nephrology polyclinic of Pamukkale University Medical Faculty and followed-up with the diagnosis of urinary tract infection were retrospectively evaluated. The study included 197 patients diagnosed with acute pyelonephritis (confirmed by urine culture and clinical evidence) and undergoing dimercaptosuccinic acid (DMSA) scintigraphic imaging. The clinical evidence (fever, recurrent UTI, voiding dysfunction etc.), laboratory evidence (C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), white blood cell (WBC) count, polymorphonuclear leukocyte (PNL) count, mean platelet volume (MPV), platelet count, serum urea and creatinine levels) and imaging evidence (urinary tract system ultrasonography (USG), voiding cystourethrography (VCUG) and DMSA scintigraphy) of the patients detected at admission and obtained by anamnesis were evaluated. Results: The number of the female patients (n=153) was found significantly higher than number of the male patients (n=44) ( p <0.001). It was detected that pretreatment fever of 38°C and over, persisting clinical evidence for 2 days or longer, the presence of recurrent UTI and high levels of WBC, PNL, ESR and CRP significantly increased renal damage in the patients (p<0.001). It was determined that USG and VCUG have low sensitivity regarding prediction of renal damage. Conclusion: Determination of renal damage rate by clinical and laboratory data detected at patient admission may contribute to a reduction in morbidity and mortality rates by applying an appropriate follow-up and treatment modality.
