Abstract:
A classification system for ectopic ureteroceles based on renal unit jeopardy is presented. This system has been found to be predictive of response to surgical reconstruction and is thus helpful in selecting the initial reconstructive approach. Specific guidelines for the selection of an appropriate surgical strategy are provided.
