We have extended the previous fluctuation exchange approximation for the two-dimensional Hubbard model to a Fermi surface geometry approximating that of the YBazCu307\_y cuprates. In spite of the poor nesting of this Fermi surface we obtain a broad commensurate peak in the spectral density of the dy
