Trabalho prospectivo estudando a matriz extracelular da parede vesical em pacientes com extrofia vesical comparados ao grupo controle, pela microscopia óptica comum e luz polarizada com morfometria, quantificando-se as fibras colágenas e reticulínicas. Estudou-se 17 pacientes de ambos os sexos, biopsiando-se toda a parede vesical e empregando colorações HE, PS e Reticulina. Diferenças estatisticamente significantes foram notadas na análise quantitativa de fibras colágenas e reticulínicas o número de fibras colágenas foi significativamente maior e o número de fibras reticulínicas foi menor no grupo de pacientes com extrofia vesical quando comparado ao grupo controle. / A prospective study was done to evaluate the detrusor muscle\'s extracellular matrix in classical bladder exstrophy in comparison to a control group, by use of light microscopy and polarization method with morphometry, to quantify collagen and reticular fibers. Seventeen patients from both sexes were analysed and samples were obtained from the bladder and stained with Haematoxylin-eosin, Picrosirius red and the silver impregnation method. There were significant differences when comparing the quantity of collagen and reticular fibers. The collagen fibers were more abundant in the exstrophy bladders compared to controls, while the reticular fibers were present in smaller amounts.
