The paraureteric diverticulum in childhood.

The clinical features and the results of surgical treatment in 27 children with a paraureteric diverticulum treated between 1969 and 1979 were reviewed. The condition is commoner in males. Vesicoureteric reflux and double ureters were associated findings and together with the diverticulum accounted for the high incidence of urinary infection as a presenting feature. In only 2 patients with the diverticulum seen on excretion urography, but micturating cystography confirmed the diagnosis in 24 patients. Conservative treatment with continuous chemotherapy is satisfactory when the diverticulum is small and prior to the development of vesicoureteric reflux. In the later stages, excision of the diverticulum and reimplantation of the contiguous ureter is the surgical treatment of choice.
