    Abstract:
    There is general acceptance that the best substitute for a damaged distal ureter is an elongated bladder and that the bladder psoas hitch is the most reliable procedure. Nevertheless, it is not always sufficient to bridge a long ureteric gap. In order to obtain an equally safe but wider bladder elongation than the psoas hitch can provide, we have previously studied the effect of several Z-shaped incisions on isolated pig bladders. The aim of the present study was to verify, in vivo, the efficacy and safety of the new technique. Five sheep underwent the psoas hitch procedure and 6 the Z-plasty procedure. The results showed that Z-plasty provides an equally safe but longer bladder elongation than the psoas hitch procedure.
