[Contribution of clinical, biological and radiological parameters in the diagnosis of urinary infection localization]. / Apport des parametres cliniques biologiques et radiologiques dans le diagnostic de localisation de l'infection urinaire.

Urinary infection was a problem in pediatrics. Currently the diagnosis is easy but it is hard to diagnosis the localisation of the infection. We have to go fast and precisely to treat correctly this infection and diminich the possibility of developing renal scars. Dimercaptosuccinic acid (DMSA) scintigraphy is a reference exam for detection acute renal lesions. We have realised a prospective study in 29 children presenting urinary tract infection. In whom a DMSA scintigraphy is realised between the one day and 30 days after the infection. We study the sensibility ans the specificity of clinical, biological and radiological parameter for the diagnosis of localisation of the infection. The better parameter of sensibility of upper urinary tract infection is of fever, and the better parameter of specificity is the association of fever, echo Doppler renal and VS.
