Previous issue date: 2013-03-04 / OBJECTIVE: To calculate the frequencies of acute pyelonephritis and renal scarring in youngers than two years old through scintigraphy with 99mTcDMSA with first episode of UTI in a Brazilian university hospital and comparing with international literature. MATERIALS AND METHODS: We reviewed reports scintigraphy of youngers than two years old who underwent scintigraphy with 99mTcDMSA in a university hospital in Rio Grande do Sul, between 2006 and 2009 to search for APN and renal scarring. It was also revised the presence of vesicoureteral reflux, early use of antibiotics, and comorbidities that were recorded in e lectronic records. The sample size calculation was based on a systematic review study and obtained a minimum of 147 patients. We excluded patients with no electronic record. RESULTS: 157 children met the inclusion criteria, where 48 had APN and 8 of these had renal scars. There was no statistical difference in the association of VUR and APN (p=1.0) as well as among all comorbidities (p=0.470). There was no significance relation to early use of antibiotics and APN (p=0.130) and renal scarring (p=0.720). CONCLUSION: The frequency of renal scarring and APN obtained agree with the results of most studies. / OBJETIVO: Calcular as frequ?ncias de pielonefrite aguda (PNA) e cicatriz renal em pacientes menores de dois anos com cintilografia renal com 99mTcDMSA com primeiro quadro de ITU em hospital universit?rio brasileiro comparando com dados da literatura internacional. MATERIAIS E M?TODOS: Foram revisados laudos cintilogr?ficos de crian?as menores de dois anos de idade que realizaram cintilografia renal com 99mTcDMSA em um hospital universit?rio de no Rio Grande do Sul, entre 2006 e 2009 para pesquisa de PNA/cicatriz renal. Revisouse a presen?a de refluxo v?sicoureteral (RVU), uso precoce de antibi?tico, e presen?a de comorbidades que constassem nos prontu?rios eletr?nicos. Calculouse a amostra baseado num estudo de revis?o sistem?tica e obtevese um m?nimo de 147 pacientes. Excluiu-se pacientes sem registro eletr?nico. RESULTADOS: 157 crian?as preencheram crit?rios de inclus?o do estudo, 48 tiveram PNA e 8 destes apresentaram cicatriz renal. Nem a idade e g?nero dos pacientes apresentaram associa??o significativa com PNA (p=0,405; p=0,124 respectivamente). N?o houve diferen?a estat?stica nas associa??es de RVU e PNA (p=1,0) e outras comorbidades (p=0,470); e em rela??o ao uso precoce de antibi?tico com PNA (p=0,130) e cicatriz renal (p=0,720). CONCLUS?O: As frequ?ncias de PNA e cicatriz renal obtidas concordam com os resultados da maioria dos estudos publicados
