Reflux--a retrospective study of 100 ureteric reimplantations by the Politano-Leadbetter method and 100 by the Cohen technique.

The results of 100 consecutive ureteric reimplantations using the Politano-Leadbetter technique were compared with those of 100 cases operated on by the Cohen technique. This retrospective study was concerned only with the effect of the operation on the ureterovesical junction. Cure of reflux was achieved in 88 Politano-Leadbetter reimplantations and in 97 Cohen reimplantations. Both groups and the results are analysed.
