[Results of long-term follow-up of patients with ureterosigmoidostomy]

The late results of ureterosigmoidostomy (US) have been known for many years; however, the incidence rates of second neoplasms that have been reported for the foregoing procedure are in disagreement with our own findings. A comprehensive review we had undertaken demonstrates that although it is a risk factor, its true incidence is much lower than that widely-accepted and published. Its very long latency period make it a currently valid surgical procedure in some adult conditions.
