Final results of Coffey's ureterosigmoidostomy in noncarcinomatous diseases.

The present report on 67 patients, in whom a ureterosigmoidostomy was performed on the ground of a benign indication, is to take a critical attitude towards ureterosigmoidostomy. In about 60 per cent of the cases satisfactory or good results can be achieved. Final comparisons with other methods of derivation cannot be made, since a sufficiently great number of late results is not yet available. In our opinion, it is doubtful if there will ever be an alternative. The operator's judgment and experience will always play an important role. Certainly the results can be improved by a lifelong close observation of the patients.
