A new concept in vesical conduits.

To overcome the problems associated with cutaneous vesicostomies a new concept in vesical conduits was developed and performed in 13 dogs. The principle of the new conduit is the utilization of minimal bladder tissue to create a stoma analogous to that of the ileal conduit and to perform an antireflux vesicoureteral anastomosis. Preliminary results with the animal studies indicate that the vesicostomy's major faults have been successfully surmounted by this new procedure.
